Check usb pioneer. The radio does not read the flash drive: the main causes of the problem. Why doesn't the radio read the flash drive in the car?

5 minutes to read. Views 13.3k.

Pioneer car multimedia centers are equipped with a built-in diagnostic system that displays detected error codes on the display. The appearance of error 19 on the Pioneer radio with a flash drive occurs when information is incorrectly read from the drive. Moreover, the error code does not depend on the switching method and design features of the external device for storing information.

What does error 19 mean?

Error 19 code is displayed on Pioneer radios if executable files or documents are detected on the drive, the decoding of which is not supported by the built-in controller. Also, an information message appears when the head unit does not see the flash drive installed in the USB connector. A malfunction that appears means that the files on the drive have been damaged, accompanied by an error being recorded in the radio's memory.

If the Pioneer radio does not read the flash drive, then it is recommended to do the following:

Turn off the ignition system while simultaneously cutting off the power supply to the head unit.
With the radio turned off, you need to disconnect the external storage device.
Turn on the ignition system and the player that you want to switch to radio reception mode.
Connect the equipment to the reading connector.

A similar error removal technique is offered by the manufacturer, but it allows you to correct the situation only in the event of a single failure.

Many users note that rebooting and reinstalling the drives allows the radio to operate for 2-3 minutes, after which the malfunction occurs again.

The cause of the defect is a design problem with USB, or more precisely, with an electronic voltage stabilizer. The device chip does not have a cooling radiator; an additional layer of paste that removes heat is not applied. The device is located in the far corner of the radio casing, where air stagnation is observed.

All these reasons lead to overheating of the controller and failures when reading external drives.

A similar error is displayed when connecting a phone or smartphones based on Android. The manufacturer claims the permissible current for a USB port is up to 1 A; on budget Pioneer equipment, the front connector is designed for a current of no higher than 0.5 A.

See » How to connect a Mystery car radio

The operating instructions indicate that the port can be used to charge the batteries of smartphones and cellular devices. But the charging current (with a severely discharged battery) reaches 2.0 A and higher, which leads to an overload of the circuit. To reduce the likelihood of a defect occurring, it is recommended to use equipment with a battery charged 50% or more. A failure also occurs if the user connected equipment via USB that is not compatible with the head unit (for example, external CD players).

How to fix the error and turn on the flash drive

Basic methods for ensuring stable operation of the drive:

To check the contents of the drive, you need to turn on the device via a computer or laptop, and then view the list of documents using the file manager. It is recommended to set the mode to show hidden files that may cause malfunctions. Suspicious documents and files with the wrong extension must be deleted. If the user simultaneously uses the drive to store various documentation and musical compositions, then the purchase of an additional flash drive or memory card will be required.
If malfunctions continue, the cause may be files infected with computer viruses. At the same time, they are not able to damage the head acoustic device, but during switching they slow down reading, which leads to an error. You can fix the problem using computer anti-virus programs.
If the equipment continues to operate incorrectly, it is necessary to format the flash drive for the radio. It must be remembered that formatting irreversibly deletes all existing information. If the user stored important documentation on the drive, then it should first be saved to the computer’s hard drive. The compatible format of flash drives for the Pioneer radio is only FAT 16 or 32. When using the NTFC standard, the drive will not be readable.
A number of owners experience an error when connecting drives via an extension cable. The defect occurs due to the additional resistance of the cord; it is recommended to install the flash drive directly into the USB port.
Check the head equipment setup menu. In the parameters field for external USB drives, the value “memory” is entered. When using the "android" option, external devices are not recognized.

To ensure reliable operation of the drive, it is necessary to safely shut down the product. To do this, you need to switch the radio to the mode of receiving radio station signals, and then remove the flash drive from the USB connector.

If the user removes the drive while reading or writing information, there is a risk of file damage.

When switching again, the radio will try to read the damaged document, which can cause the system to freeze and error 19 to appear on the display.

Algorithm for restoring the drive's functionality:

Connect the device to the computer and copy all information to a separate folder previously created on your hard drive.
Proceed to format the connected flash drive, turn on the dialog box with the right mouse button.
In the window that appears, you need to set the file system standard to FAT 32. Additionally, you need to change the cluster size parameter to standard. The computer operating system offers a value of 4096 bytes, which is not recommended. You also need to remove the confirmation icon from the “quick format” field.
Start formatting, processing time depends on the size of the drive.
After processing is completed, a new formatting process must be started. In this case, you need to check the confirmation box for the “quick format” operation; the cluster size remains standard.
Carry out reformatting, which is started by clicking on the “start” button.
After completing the procedure, you need to clean the surface of the drive a third time. It is necessary to unconfirm the “quick format” operation; other parameters do not need to be adjusted.
After the third formatting, you need to transfer back the music compositions.
Disconnect the drive from the computer using the safe removal procedure. The procedure allows you to restore the operation of only some drives; it does not work for all modifications of Pioneer radios.
Test the connections to the radio.

If the head unit stops reading USB drives after incorrect removal of the product, then you need to reset the memory. For this purpose, there is a special reset button located on the front panel of the radio or under it (in the case of a removable unit). A thin, pointed object is used to press. It is possible to clear the memory by turning off the power for 2-3 minutes.

Any technology, even the best, can fail its owner at some point. The Pioneer radio is no exception in this sense. Even in this device from a well-known manufacturer, annoying errors periodically occur that can confuse even an experienced car enthusiast. What are these errors and why do they occur? Is it possible to eliminate them yourself? About elimination typical mistakes with flash drives type 23 and 19 on the Pioneer and we’ll talk further.

List of the most famous Pioneer radio errors and how to fix them

Most often problems arise with USB drives. Let's start with them.

CHECK USB error

The message CHECK USB appears on the display of the radio when it refuses to read a flash drive or some other storage device (for example, a portable HDD). This message indicates a power failure in the USB device. A failure may occur either due to the incompatibility of this drive with the radio, or due to a short circuit in the connector itself.

should be carefully inspected first USB port on the radio. Perhaps dirt or some foreign object got into it, which caused a short circuit;
if there is no short circuit, you should pay attention to the amount of current consumed by the USB drive (this figure can be found in the instructions for the device). The fact is that some flash drives require a current slightly higher than 500 mA for normal operation, while the radio is designed for exactly 500 mA, which leads to the CHECK USB error. There is only one way out: replace the flash drive, having previously specified the amount of current consumed;

ERROR 23 with flash drive

When error 23 occurs, the user sees the message ERROR-23 on the radio display. This happens immediately after installing the flash drive into the USB port of the radio. The error means that the file system in which the flash drive is formatted is incompatible with this radio. That is, if the drive was formatted in the outdated FAT32 (or even FAT16) system, the error is guaranteed to appear.

Solution: format the flash drive to NTFS system, supported by all Pioneer radios.

Troubleshooting Error 19

This error is shown on the display as ERROR-19. This may occur either due to improper formatting of the drive, or due to storing files on it with extensions other than .mp3 (such as .doc, .exe, .txt, .pdf, .com). MP3 files can also cause an error if they are stored in many folders with a high level of nesting and an abundance of Cyrillic characters in the names.

remove all extraneous files from the flash drive, except mp3. If mp3 files are “scattered” across many folders, organize their structure by placing them in 3–4 new folders, and the names of these folders must be written in Latin letters;
If this does not help, you should insert the USB flash drive into the computer and check it for viruses. As a rule, viruses do not harm the radio, but they often copy executable files onto a flash drive that the standard one “does not see.” file manager Windows, but the radio “sees” perfectly;
if the anti-virus program for some reason failed to remove the detected viruses, there is only one thing left: completely formatting the drive in the NTFS system, as shown above;

ERROR 11

There are two problems that cause ERROR-11 to appear on the display. Either the CD inserted into the radio is seriously scratched or covered with dirt, or there is some kind of mechanical fault in the radio (most often the CD drive of the radio fails).

remove the disc and gently wipe it with a piece of soft cloth;
clean the drive lens using a special cleaning disc;
if it doesn’t help, there is only one way out: contact the nearest Pioneer company;

Power failure 10 on the car radio

Error notification ERROR-10 means either a power failure in the Bluetooth module or some other electrical fault (but in practice, Bluetooth is usually the source of trouble). This error has nothing to do with storage media.

The ignition key of the car is set to the OFF position, after which it is moved either to the ACC or ON position. The power source is switched to some other device, and then back to the radio;
if these actions do not bring results, you must contact the service center;

Amplifier error

If problems arise with the amplifier in the car, the sound suddenly disappears (usually while a track is playing), after which the driver sees the message ERROR-AMP on the display. The inscription says that everything is fine with the radio and disc and the reason needs to be looked for elsewhere. Most often, the source of the error is a damaged, shorted or simply loosely connected wiring running from the radio to the amplifier.

Carefully inspect the wires for breaks, short circuits, fraying or damaged insulation. If something like this is found, the damaged wire is replaced. Typically this will clear the amplifier error;
If there is no damage to the wires, and the problem has not disappeared, you should check the tightness of all plugs, both on the amplifier and on the radio. The best option- take them out one by one and insert them into the sockets again, with a little effort;
if this does not lead to anything, then there is a malfunction of the amplifier. It must be removed and taken to the nearest service center for repair;

Protect message: what is the problem and how to fix it

The inscription ERROR-PROTECT appears on the display immediately after connecting a flash drive or other portable storage medium. The reason this error appears is that the files on the connected media were encoded using a digital digital management system. Windows rights Media DRM. The protected files themselves usually have the extension .wma.

replacing files: if the tracks on a flash drive are not of great value, you can simply erase them and place similar mp3 files in their place;
if there is nothing to replace the protected files with, you can use one of the many format converter programs and reformat wma files to mp3;

Here is an example of conversion using the Format Factory program (which is free for home use and which can be freely downloaded from the developers’ website).

Most errors that appear on the Pioneer radio display can be eliminated by the user themselves, since they are most often associated with either incorrect formatting of the media or its poor condition. The only exception to this rule, perhaps, can be error 10: if it turns out that it is not related to the Bluetooth module, then it will not be possible to do without expensive repairs.

In this article we will try to answer the questions:

What is a complex fault?

How can error codes help when repairing car radios?

In the practice of repairing car radios, there are often cases when, in order to restore the operation of the car radio, it is necessary to find and eliminate not one specific malfunction, but several. It’s good if the breakdowns are not related to each other or relate to different electronic components of the car radio (for example: no sound - the amplifier chip is faulty; no disk reading - the laser reader lens is dirty).

What if both faults are in the CD drive? With such malfunctions, the process of diagnosis and repair becomes difficult, since, having eliminated one malfunction, we are immediately faced with the manifestation of another. Such a malfunction with several causes can be called complex.

The Pioneer car radio came to the repair table due to the lack of reading from the CD.

Upon external inspection, it was noticed that when the disk eject button is pressed, the process of ejecting the disk occurs slowly. The car radio was also heavily soiled with dust.

It is no secret that when heavily soiled, the optics are the first to suffer - the surface of the laser reader lens becomes covered with fine dust and this prevents the laser beam from focusing on the surface of the CD. In this case, there may be failures during playback (the sound “hiccups”), failures during the initial loading of the disc (“NO DISK”, “Error”), a long search for a recording when switching to another song. Do not forget that the cause of such a malfunction can be not only contamination of the optics, but also degradation of the laser diode in the optical unit.

For car radios, if any malfunctions occur, an error code appears on the display. Knowing the decoding of the error code, you can more quickly find the faulty unit and do not waste time on diagnostics. So, for example, on the Pioneer DEH-P3500MP car radio in question, when turning on and loading a disc, the message “ERROR-11” appeared on the display. At the same time, spinning of the disk was observed - which means the spindle motor is in order.

ERROR-11

If you refer to the service documentation for this car radio model, the code “ERROR-11” stands for: - No beam focusing. Well, everything is quite simple here, as already mentioned, the violation of the focusing of the beam is associated with contamination of the car radio with dust.

In this case, it may be necessary to completely clean all mechanical parts of the car radio and its housing. Cleaning the laser reader lens is made more difficult by the fact that it is necessary to disassemble the CD mechanism and remove the laser reader from it. Read about how to disassemble the CD mechanism (another type of drive).

After the laser unit is cleaned of dust, the operation of the car radio can be completely restored. But we are looking at a complex malfunction.

Upon further testing the operation of the car radio on several MP3 discs, it turned out that when switching several songs forward or backward, a failure occurs. After a long and unsuccessful search for the desired track, the ominous inscription “ERROR-30” appeared on the car radio display.

ERROR-30

Also, when playing a recording from a disc, errors (“stuttering” or “croaking”) were observed, and at times, immediately after loading an MP3 disc, a mysterious message “NO AUDIO” appeared.

CDs with regular encoding (Compact Disc Digital Audio) played more or less normally and without glitches. It is known that with normal recording (Compact Disc Digital Audio) without compaction, as, for example, in MP3, the error correction and correction system is easier to restore the read data if it is poorly read from the disk.

In this case, you can make an erroneous conclusion that the laser optical unit is faulty (degradation of the laser diode), and it needs to be replaced with a new one. But there are pitfalls here. Let's remember what errors the car radio gave us and look at the service documentation.

From the service manual for the Pioneer DEH-P3500MP car radio we find out that the error code “ERROR-30” stands for: - Search time exceeded. And if you think logically, you can come to the conclusion that some of the CD drive motors are faulty.

It turned out that the cause of the “ERROR-30” error in this case was the laser reader positioning motor. It was he who produced low revs, which led to failures when playing and switching to another track. Remember that the disk loading process was slower than usual. Considering that this type The CD drive has a design where 2 motors are used and the positioning motor also performs the function of loading the disc into the CD drive, then it becomes clear that the reason is precisely in the positioning motor.

After replacing the positioning motor (marked FF-050SB-11170; D/V9.0) with a similar motor marked (FF-050SB-13130; D/V5.9), the fault completely disappeared, and no failures were observed during testing.

Laser Reader Positioning Motor

It is also worth paying attention to the fact that when loading some MP3 discs, the Pioneer DEH-P3500MP car radio displays the error code “ERROR-23” on the display ( Invalid data format) and the recording from the disc cannot be played back.

ERROR-23

The reason is that the recording format of this MP3 disc does not comply with the ISO9660 Level1, Level2 specification. The car radio gives an error and refuses to read the disc. Unfortunately, nothing can be done here, since the processor decoding the recording does not support this format records.

This is how we used an example to look at how to fix a complex problem in a Pioneer car radio. At the same time, the causes of the errors were eliminated one by one:

“ERROR-11” – severe contamination of the optical unit with dust (resolved by cleaning the lens);

“ERROR-30” – malfunction of the positioning motor and disk loading/unloading (resolved by replacing the positioning motor).

Both malfunctions are related to the operation of the CD mechanism, and this creates confusion and encourages an erroneous judgment about the causes of the malfunction.

It is quite difficult to imagine a car without a radio. It is installed both by the manufacturer before the vehicle is released, and by the owner himself. The value of the radio is quite large. It allows you to enjoy music while on the road, listen to the radio, find out news and other important information.

Radio with flash drive: features

Modern Pioneer radios can read not only discs, but also flash drives. This is very convenient, as it allows the driver to record musical compositions independently. If necessary, they can be easily replaced with new ones. The playback quality is quite high and does not depend on what media is used.

Today, most people prefer such devices. Because they have more opportunities. In addition, they are convenient to use and economical. There is no need to spend extra money on purchasing new disks.

Error on Pioneer radio: what does it mean?

But as practice shows, any device can fail. The radio was no exception. There are breakdowns that are clearly expressed. In such cases, the device does not turn on and does not work at all. To fix this problem, you will definitely need the help of a specialist. But there is another type of breakdown.

They are reproduced on the device display in the form of some letters and symbols. To understand their meaning, you will need to use the instruction manual. It is included with all radio manufacturers and contains useful information. It is important to familiarize yourself with it before using the radio.

Error 23 on the radio

Errors in the operation of the radio can occur at any time. And it doesn’t matter at all who its manufacturer is Pioneer and another company. One of the most common is error 23; it is typical for a radio with a flash drive. Anyone can encounter it. The problem is that the radio does not read the flash drive. As a result, the musical compositions that are on it are not reproduced.

There are many reasons for this problem. But before you start identifying them, you should check the flash drive for viruses. They can also interfere with its work. This is quite easy to do. To do this you will need a computer and a special anti-virus program. If the test is passed and its result is positive, then the reason is different.

Error 23 on the Pioneer radio with a flash drive: reasons

This problem may occur for reasons such as:

Music file format mismatch. This item must be strictly monitored. Since the device will not be able to read songs recorded in another format. For example, if the Pioneer radio is designed for MP-3 expansion, then only such files need to be downloaded;
Incorrect file names. It is easy to determine this reason. Basically, some files play and others don't. This suggests that some are written in the Cyrillic language that is typical for the radio, while others are not. Perhaps, in general, it works in the Latin alphabet. Then all files will need to be renamed so that their names contain only letters of the Latin alphabet;
Flash drive failure. It is necessary to check the drive for serviceability. Perhaps this is the first thing that follows in a situation of error. The flash drive may have failed. To determine its status, you need to connect it to another device. For example, a computer. If it is not readable on it either, then the reason is a faulty drive. This can happen either due to mechanical damage or for another reason. In some cases, the operation of the drive is quite possible;
The connector into which the flash drive is connected to the radio is faulty. This may happen if the device is used frequently or incorrectly. Its contacts become loose during operation, which disrupts their function. It is possible to correct the situation, but it is not easy. It is better to contact the service center specialists;
The discrepancy between the volume of the flash drive and the car radio. This mainly concerns a large amount of information. Basically, radio tape recorders are designed for flash drives of no more than 4 GB. And if this value is exceeded, the device is unlikely to work. But this does not mean that the flash drive should only be of this size. There are some tricks that are great for solving this problem. So, the drive can be divided into segments that will contain the necessary amount of information;
The file system of the flash drive does not match. Almost all radios are individual and can only work with a certain format. You can find out which one is typical for your radio from the device’s operating instructions. And you just need to format the flash drive.

The radio displays error 23: how to format a flash drive?

Quite often the flash drive is in NTFS format, but the Pioneer radio requires file system FAT16 or FAT32. Such a discrepancy will lead to the fact that musical compositions will not be played, and the radio will display error 23.

But there is no need to be upset. Because there is a solution that can help you. It consists of carrying out the operation of formatting a flash drive. This is not difficult to do and anyone can do it.

You need to insert the drive into your computer. Then on its icon that appears on the screen, click right click mouse and select the word format. Set this command to be executed. To do this, just click the word start in the new window.

The system will warn you that this procedure will be performed with the deletion of all data that was previously saved on the drive. These are mandatory conditions. Therefore, it is necessary to agree to its implementation.

After the work is completed, a window will appear on the screen. It will say this. What you need to do is click OK and remove the drive from the computer. This procedure is very simple and is shown in the photo. Therefore, difficulties in carrying it out are unlikely to arise.

As practice shows, there are no unsolved problems. Don't be alarmed by errors that may appear on the display of your Pioneer radio. Almost everything can be fixed and the device can resume normal operation.

In contact with

The interior of each vehicle is equipped with a radio. The motorist himself is interested in ensuring that the car radio is not only present, but is always in working order. How upset motorists are when one day they are faced with a problem when the Pioneer radio no longer reads the flash drive. Drivers don’t want to agree with this and drive in absolute silence, so they try to figure out what error 23 is on the Pioneer radio; the flash drive refuses to play music files when it occurs.

When using a flash drive on a Pioneer radio, error 23 may occur.

Musical accompaniment increases the level of comfort when moving. The trip becomes exciting and unnoticed. Drivers can not only listen to their favorite tunes, but also receive useful portions of news information. Modern radios can play music files from an optical disc or flash drive. Thanks to this, motorists can independently create music albums for themselves, as well as change them as the desire arises.

Causes and solutions to the error

There are many reasons why the radio may go silent. Of course, if this mechanical damage, failure of the hardware, not everyone is able to fix the problem on their own. In these situations, you have to contact service centers for help.

Along with this, variants of problems may arise that can easily be eliminated if only you first study a lot of useful sources of information. First of all, it is very important to read all the recommendations contained in the operating instructions for the sound reproducing device.

The most common problem due to which music does not play is “Error 23” on the Pioneer radio; the flash drive is not readable. What to do in such a situation, how to prevent the occurrence of such a problem in the future, it is important to understand immediately.

Causes

A flash drive may become unusable and unreadable if it is penetrated." uninvited guests" To identify them and subsequently say goodbye to them, users recommend inserting a removable drive into the USB connector of the computer. After this, the flash drive will definitely appear as removable drive, and it will be possible to scan it antivirus program. If your antivirus program is updated very rarely, it may not be able to eliminate all viruses. In this case, it is useful to first update the anti-virus databases, and only then scan removable media. You can use online antivirus software resources.

ATTENTION. If the flash drive turns out to be clean and free of viruses, you can continue to look for problems in a different direction.

On the Internet, where audio files are most often downloaded and recorded, music can be presented in any format. Before recording music files onto a flash drive, it is important to make sure that this format will be successfully read by your radio. In most cases, files with the MP3 extension can be easily played. When downloading another audio file format, you should not hastily record it onto removable media. You can first reformat it, then error 23 associated with the failure of the flash drive on the Pioneer radio can be eliminated or prevented.

A refusal to play music can also be caused by something as trivial as incorrect recording of file names. In particular, some radios are capable of responding only to the Cyrillic alphabet, while others, on the contrary, to the Latin alphabet. In this case, it is useful to pay attention to what music is being played, and then, by analogy, rename those files that were impossible to play.

It does not at all prevent the owner of the car radio from examining both the playback device itself and the flash drive. Often the cause is mechanical damage or a faulty connector. It is better to delegate such technical faults to those who have sufficient experience in repairing such devices.

If the Pioneer radio does not read the flash drive, “Error 23” appears, pay attention to the capacity of the removable drive. In most cases, car radios are ready to “cooperate” only with drives whose capacity does not exceed 4 GB. If you have a more advanced option, don’t be upset, you can use some tricks by dividing the drive into sectors, then your “cool” flash drive will be successfully adapted for a radio.

IMPORTANT. The problem may also be that you formatted the removable drive in a format that is not suitable for display by the car radio.

Formatting a removable drive

The latest generations of flash drives are accompanied by the NTFS format. Unfortunately, car radios cannot recognize this format because they only support FAT16 and FAT32. Even such a banal format mismatch can trigger error 23.

Fortunately, solving this problem is quite simple. To do this, you simply need to format the removable drive using computer equipment.

The flash drive needs to be inserted into the USB connector, after it is displayed in the “Computer” dialog box, right-click on it. In the menu that opens, go to the “Format” option.

After opening the formatting window, it is important to make the desired changes. In particular, set the format to FAT16 or FAT32. Of course, such a process not only converts the removable drive to a different format, but also completely cleans it, deleting all the files that were stored on it before the formatting process began.

ADVICE. Taking this into account, it is important to first transfer to your computer those files that would be painful for you to lose and, moreover, quite difficult to recover.

In the “Cluster Size” line, it is best to select the “ Standard size cluster”, then click on the “Start” button. The utility will warn you that all files will be lost, agree to this warning and confirm the continuation of its actions. After a short period of time, a new window will appear on the screen with the inscription “Format completed”.

Now you should write music files in the correct format onto such a prepared flash drive, then insert the removable drive into the USB connector of the car radio and enjoy the wonderful sound of music.

So, the process of eliminating error 23 is not so complicated. It is enough to carefully study the useful recommendations, follow the recommended actions consistently and rejoice at the excellent result to which you made your own efforts.

Any technology, even the best, can fail its owner at some point. The Pioneer radio is no exception in this sense. Even in this device from a well-known manufacturer, annoying errors periodically occur that can confuse even an experienced car enthusiast. What are these errors and why do they occur? Is it possible to eliminate them yourself? We’ll talk further about eliminating typical errors with flash drives of type 23 and 19 on Pioneer.

List of the most famous Pioneer radio errors and how to fix them

Most often problems arise with USB drives. Let's start with them.

CHECK USB error

The message CHECK USB appears on the display of the radio when it refuses to read a flash drive or some other storage device (for example, a portable hard drive). This message indicates a power failure in the USB device. A failure may occur either due to the incompatibility of this drive with the radio, or due to a short circuit in the connector itself.

First you should carefully inspect the USB port on the radio. Perhaps dirt or some foreign object got into it, which caused a short circuit;
if there is no short circuit, you should pay attention to the amount of current consumed by the USB drive (this figure can be found in the instructions for the device). The fact is that some flash drives require a current slightly higher than 500 mA for normal operation, while the radio is designed for exactly 500 mA, which leads to the CHECK USB error. There is only one way out: replace the flash drive, having previously specified the amount of current consumed;

ERROR 23 with flash drive

Solution: format the flash drive in the NTFS system, supported by all Pioneer radios.

Troubleshooting Error 19

remove all extraneous files from the flash drive, except mp3. If mp3 files are “scattered” across many folders, organize their structure by placing them in 3–4 new folders, and the names of these folders must be written in Latin letters;
If this does not help, you should insert the USB flash drive into the computer and check it for viruses. As a rule, viruses do not harm the radio, but often copy executable files onto a flash drive, which the standard Windows file manager does not “see”, but the radio “sees” perfectly;
if the anti-virus program for some reason failed to remove the detected viruses, there is only one thing left: completely formatting the drive in the NTFS system, as shown above;

ERROR 11

remove the disc and gently wipe it with a piece of soft cloth;
clean the drive lens using a special cleaning disc;
if it doesn’t help, there is only one way out: contact the nearest Pioneer service center;

Power failure 10 on the car radio

The ignition key of the car is set to the OFF position, after which it is moved either to the ACC or ON position. The power source is switched to some other device, and then back to the radio;
if these actions do not bring results, you must contact the service center;

Amplifier error

Carefully inspect the wires for breaks, short circuits, fraying or damaged insulation. If something like this is found, the damaged wire is replaced. Typically this will clear the amplifier error;
If there is no damage to the wires, and the problem has not disappeared, you should check the tightness of all plugs, both on the amplifier and on the radio. The best option is to remove them one by one and insert them into their sockets again, with a little force;
if this does not lead to anything, then there is a malfunction of the amplifier. It must be removed and taken to the nearest service center for repair;

Protect message: what is the problem and how to fix it

The inscription ERROR-PROTECT appears on the display immediately after connecting a flash drive or other portable storage medium. The reason this error appears is that the files on the connected media were encoded using the Windows Media DRM digital rights management system. The protected files themselves usually have the extension .wma.

replacing files: if the tracks on a flash drive are not of great value, you can simply erase them and place similar mp3 files in their place;
if there is nothing to replace the protected files with, you can use one of the many format converter programs and reformat wma files to mp3;

Let's give an example of conversion using the Format Factory program (which is free for home use and can be freely downloaded from the developers' website).

The program is downloaded from the official website, installed on the computer, and the start window opens. In the upper left part of the window, select the file format that is planned to be output, i.e. mp3;
after selecting the format, the following window opens in which the user is prompted to add the converted file to the program;
finally, in the third window you need to specify the location where the resulting mp3 file will be saved. After this, all you have to do is click the “OK” button and the file will begin converting to mp3 format;
