Kenwood Stereo is one of the best-selling brands in the market for car stereos. Although it is regarded as the best, it can also malfunction like any other device, and this could sometimes be a result of how it is operated.

1. Burnt Fuse

If the stereo will not turn on, then it could be that your fuse is bad. The stereo fuse should be the first thing to check, and it is located at the back of the stereo. 

If the fuse seems to be burnt, then you would need to replace it with a fuse of the same amperage rating.

2. Error Message

If a code in the stereo display that reads “ERROR 05” appears whenever a disc is inserted, it could only mean that your disc is unreadable, and perhaps you have placed the DVD wrongly. If it is “ERROR 77” that appears, then your stereo unit is malfunctioning. 

If this is the case with your Kenwood stereo, press the unit’s reset button and wait a few moments before reconnecting the device back on.

If after applying this technique, the error message remains, you would need to take it to a service center for it to be checked and fixed. 

3. Power Issues

If your device is not coming up, it could be that it wasn’t turned on properly or the power button is malfunctioning. When putting on your Kenwood car stereo, make sure the power button is pressed and the light is on.

If the light fails to come up and your device is not coming on, then it could mean that your power button is faulty. In this situation, you would need to take it to the service center for repair or replacement.

4. Loose Connection

If you are unable to hear any sound when you turn on your stereo, then it could be that your wiring connections are loose, especially if you have just worked on your stereo. 

Check the wiring on the back of the car stereo. Make sure wires are connected properly, if they are not, reconnect them in their right locations. Also, look for wiring shorts. This can happen when two or more wires’ bare metal surfaces are touching one another.

5. N/A Device

If the “N/A Device” warning shows on the unit, check the device connected to the sound system. If you connect an MP3 player to the unit, check the owner’s manual to ensure it is a device supported by the stereo system. Remove the MP3 player and reconnect it if it is a compatible device.

6. Issues with CDs

If your CD is not playing correctly, then the problem could be with your CD. Make sure your CD is properly cleaned before inserting it. 

When cleaning a CD, do not wipe it in a circular motion, but instead use straight strokes that go from the center outward. Hence, you may also want to check to make sure the disc has been placed in the proper slot.

7. Bluetooth Connection Issues

If your car stereo was connected to Bluetooth but suddenly does not connect anymore, then you need to search for the Bluetooth device again and click on connect to make sure you have secured a proper connection with your device. 

If the device name isn’t found, you can refresh the search for Bluetooth devices under the Bluetooth settings page on your device and then connect. If this does not work, try deleting the pairing information from both the unit and the Bluetooth device, then perform pairing again.
