Car radio with USB input
Most modern car radios have a USB input for reading audio files from a flash drive. This method of storing and reproducing audio information is more reliable, noise-resistant, informative and convenient from a consumer point of view than CDs and DVDs.
Many manufacturers are gradually abandoning disk drives in favor of USB and other electronic storage media.
However, the playback method via a USB port has one fundamental drawback: some flash drives and various car radios refuse to be read. Moreover, a situation very often occurs when one radio tape recorder reads the same flash drive without problems, but the other completely refuses to “see” it.
Why doesn't the radio read the flash drive in the car?
The main reasons that the car radio does not see the USB flash drive are:
1. Lack of file system support for the car radio
, in which the flash drive is formatted.
Most car radios produced before 2010 support FAT32 USB file systems. If the radio is even older, then it can only support the FAT16 file system.
New car radios, especially standard ones, may have support for the NTFS file system, and if the media is formatted in FAT32, which is more “ancient” from their point of view, problems may arise when reading audio information.
If there is no reliable information on the radio (technical characteristics) about what file system the USB port driver supports, in many cases you have to sequentially reformat the flash drive to FAT32, then to NTFS, respectively, write test audio files to it.
This can only be done using a computer (laptop, netbook). To do this, right-click on a removable disk (flash drive) connected to the computer, select “formatting” in the context menu
and then the corresponding file system.
2. Inability to read audio files stored in folders with a complex hierarchy
. Car radios produced before 2000 and inexpensive FM transmitters suffer from this disease.
If the playlist has subfolders, for example, such as root directory - Russian songs - folk - babkina, then perhaps it will not be possible to enter some folders remote from the root directory.
Therefore, on radios made before 2000, it is better to record audio files in the root directory, especially since using a computer it is not difficult to create and rewrite any playlist.
3. Exceeding flash storage capacity requirements
. Over time, the capacity of USB storage devices is rapidly increasing. Flash drives up to 8 GB, as a rule, are read by all car radios. Regarding the installation of higher-capacity media, you should check how much capacity, inclusive, is supported by the radio installed in your car.
4. Incorrect (most likely Russified) names of audio files
and folders. At best, what most non-Russian radio tape recorders do is to write the names of audio files in the form of Russian hieroglyphs, at worst, they refuse to read them.

If folder names are written in Russian, access to these folders may be denied. In any case, if a non-Russian radio model is installed in the car, it is better to rename the files and folders to English characters when creating a playlist on a flash drive.
5. Inability to read audio files recorded in other formats
associated with the lack of appropriate codecs. Many audio files can have different origins: downloaded from the Internet, recorded from a DVD, sent by friends. Therefore, their formats may differ.
Each car radio has a set of codecs that determine the types of audio files that can be played. When buying a radio, you need to pay attention to this fact. As a rule, the standard set includes the most common mp3 and wav formats. Good radios support most known formats.
But, if you inherited an old radio tape recorder, and the recording has musical value, it can always be re-encoded using special converter programs on your computer.
6. Radio software crashes
, often found in multimedia complexes with an Internet connection in case of virus infection. Nowadays, it is not uncommon for even radios connected to the Internet to start mining. At the same time, its resources are limited to almost zero. Even the usual codecs are not fast enough, and the audio file slows down or does not play at all. The same effect can be obtained by catching some kind of virus, even from a music flash drive.
Advice: check flash drives for viruses (at least with a simple antivirus program) before installing it in the radio.
7. Technical difficulites
(damage to the USB connector, driver, problems with the power bus). Such problems often occur when they try to use the USB connector of the radio to charge car gadgets.
Remember: in most car radios, a USB connector is provided only for installing a working flash drive (unless an additional purpose is specified in the technical specifications of the radio).
8. In car radios (or flash drives) of dubious origin there is another reason - “ for no reason at all.”
" Flash drives on which information is recorded in completely identical formats with the same file system and volume, one is readable, the other is not. In this case, you have to individually select flash drives for the radio, and nothing can be done.
Failure to read the flash drive by the radio due to poor contact in the connector
Quite often, the radio tape recorder stops reading the flash drive due to poor contact or its absence with the audio system connector. The seat for the USB flash drive is damaged due to frequent connection and disconnection of the drive. It is quite simple to eliminate such a defect using a soldering iron and a spare connector; let’s look at how such work is done using the example of a JVC car radio:
- Unscrew the screws on the back side of the removable panel;
- We separate the halves of the plastic case and remove the board (it is secured with latches). It is important during disassembly not to lose the spring for tilting the panel;
- Use a soldering iron to solder the old connector and install a new socket instead;
- install the board into the case and assemble the panel.
If during disassembly we find that there is poor soldering on the contacts, before changing the plug, we first try to solder it. It may happen that replacing the socket is not required, only soldering will be enough.

How to decipher the error code and fix it
Some “smart” car radios report information on the display that they specifically do not like about the USB storage device.
For example, these error codes:
- ERROR 23 – FAT32 or NTFS file system mismatch;
- ERROR-PROTECT – absence of Windows Media codec in the radio;
- CHECK USB – USB port power supply error;
- ERROR 19 – Cyrillic in file names, complex hierarchy, lack of an appropriate codec, etc.
For other types and error codes, please refer to the owner's manual for your specific brand of car stereo.
Possible problems and solutions
Although the process of recording music onto a flash drive is extremely simple and straightforward, from time to time car owners encounter various errors that prevent the playback of audio tracks in the car radio.
Why doesn't the radio see the flash drive?
The car radio does not perceive or read the USB drive inserted into it. Most often, the reason lies in the fact that the car owner is using a flash drive with too much memory. Therefore, it is recommended to study the instructions for the car radio and see what is the largest volume it can reproduce.
If the file system is NTFS, file playback may not be possible.
What should the file system be like?
The car radio may also refuse to “see” and play music if the flash drive uses the wrong file system. Often, audio systems support flash drives that use the FAT32 file system, so if it is different, for example, NTFS, then playback will be impossible.
To check the file system of your media, you need to connect it to your computer, find the flash drive in “My Computer” - right-click - select “Properties”, after which a small window will open where you need to find the “File system” item. If the NTFS system is listed there, then you should format the USB flash drive in the FAT32 file system.
Also, users of different car radios may encounter different system error notifications when using flash drives. Thus, owners of Pioneer audio recorders quite often encounter the “ERROR-23” error, which indicates that the flash drive is formatted using an incompatible file system. This problem can be easily and quickly resolved by properly formatting the flash drive on your computer.
Error “ERROR-23” indicates that the flash drive was formatted using an incompatible file system
Why are music files not being read?
The drive uses the correct file system and has an acceptable capacity, but the radio refuses to play music. It even happens that just yesterday the flash drive “played”, but today it doesn’t. In this case, you need to connect it to your computer and try to listen to your favorite songs from it.
If the drive is detected, regardless of whether it is possible to play music from the PC or not, most likely, errors have accumulated on the flash drive. Formatting the device will help get rid of them. If the media is not detected, then the flash drive is simply out of order, which means its further use is impossible.
