Stereo - Car Electronics Troubleshooting

Has your car stereo screen stopped displaying? Can a new security code for a car stereo be generated when the original is not traceable? These are some typical questions that owners may encounter. Experts provide information and clarify doubts about the working of car stereo systems when problems arise.

Read below how Experts answer these and other questions related to car stereo problems.

How to troubleshoot a new Kenwood car stereo system with an amp where the subwoofer is too strong and audio settings provide no scope for adjustment?

Check the user manual for any reference to subwoofer level control in audio settings. If there is and it does not work then the radio may have developed a fault. Faults in car stereo systems do tend to develop after they have been used for awhile. However, before assuming a system defect try a reset which could iron out the glitch. Before performing a reset disconnect the positive battery terminal for at least an hour. If this does not help then it is reasonably safe to assume this unit is defective and warrants a replacement.

How to fix a Kenwood car stereo deck where the GPS has stopped working after an unsuccessful firmware update?

If the wrong update was applied it could create a firmware issue which may be reversible. However, without a more detailed investigation it is difficult to determine precisely where the fault lies. The best way toward a solution is to send the system to a Kenwood authorized service center for a diagnostic check.

How to troubleshoot a Clarion car stereo which has power but the screen does not display?

Try a hard reset and if that does not work then disconnect the yellow and red wires at the back of the unit for awhile. Additionally, carefully remove the control panel which is detachable and clean the contacts and connector pins. If neither work then the unit will need to be opened to inspect the circuitry as there obviously is some internal failure.

How to troubleshoot a car stereo which has abruptly stopped playing from a flash drive and displays a "no audio" message?

This suggests that the head unit is not able to read from the flash drive or recognize any of the audio files stored on it. Plug the drive into a computer just to check that it has no security restrictions which prevent its files from being read. While there check that it is formatted with FAT or FAT32 since the head unit will not recognize NTFS if that is the way the drive is currently formatted. If it’s all good so far but still does not play then the USB port into which the drive is plugged might be dirty and need to be cleaned. If the drive works well on the computer but not with a cleaned port then it’s very likely that the port itself has failed and needs to be repaired.

What can be done when the security code for a Blaupunkt car stereo is forgotten and not traceable?

The security code on a car stereo is an anti-theft feature and hence very difficult to emulate or regenerate. The best way to overcome this problem is through a dealership that will generate a fresh code after establishing ownership.

Why does a car stereo play only about 100 of the 1800 songs stored on a flash drive?

In most cases the root directory of the drive accommodates only a certain number of entries which can be read by the car stereo, typically about 100 or less. It may be possible to work around this problem by restricting the number of folders to under 100 and distributing the songs in these folders according to genre or artist.

Many car stereo issues are not insurmountable but are related to settings. The key, however, is to recognize the issue and know how to work around it. This is where an Expert's insights and guidance proves to be invaluable. An Expert can diagnose a problem, analyze it, and provide a solution.
