One of the most common problems reported by car stereo owners is the stereo keeps resetting. But what could be causing this issue? The problem can occur at any time, regardless of the age and condition of your car stereo.

A Damaged or Not Connected Memory wire
So, what can you do to solve the issue? Let’s dive deeper into the possible causes and solutions. One common culprit is a poor memory wire connection. The memory wire is responsible for maintaining the settings of the stereo, like the radio frequency and time.

If this wire is disturbed or not functioning properly, it can result in frequent resetting of the car stereo. Check the thin yellow-colored wire in the stereo connection for any issue with its working. You can consider repairing the cable or replacing it to solve your problem.
The Thin yellow wire is used for a constant 12v connection to the stereo. When this wire has been damaged the stereo could turn off and turn on randomly. When this wire loses connection it will result in your radio forgetting its settings.
Fix: If you find that the Yellow wire on your aftermarket stereo is damaged or improperly connected please insure that you re-connect it.
Check your Vehicles Electrical system
Another possible cause is low power or a faulty capacitor. When the engine starts cranking, the stereo may turn off due to a low battery. The capacitor is the component inside the stereo that delivers quick backup power to the device. If it’s faulty or incapable, the stereo will reset or turn off. Replacing the capacitor with a new one can solve this problem. However, its more realistic to just purchase a new stereo.

Additionally, a fuse could play a vital role in the resetting of the car stereo. If the fuse gets damaged, it won’t receive enough power and can reset again and again. Check the fuse and examine the connections. If you find any errors, connect the wires again and see if the stereo starts working properly. If it doesn’t get resolved, consider replacing the fuse.
Fix: Verify your vehicle’s fuse dedicated to your stereo isn’t failing. If it is you’ll have to replace this fuse. After you complete all the steps in this article and remain with the same issue your probably gonna want to grab a beer, you’ll be paying for a new stereo.
Check Your Car Stereo
The head unit is also a critical component of your car’s audio system. If the wiring is not properly taped or the wires are mixed with other cables, the stereo can malfunction and face multiple issues. Examine the head carefully and make sure the wires and butt connectors are in proper condition.
Tape the wires and use the butt connectors to make sure the stereo gets the power it needs (solder works even better). Also, check if the stereo head has a built-in fuse. If necessary, change the head of the radio to make sure it doesn’t reset itself and starts working properly again.
Fix: Verify wiring is connected properly, specifically the yellow wire at the radio wiring harness. If the wiring isn’t connected properly secure it. While you’re checking the wiring behind the stereo take some time to inspect the fuse installed behind the radio.
After Your Battery Is Replaced
This is pretty common knowledge but it’s still worth mentioning. Anytime your battery is replaced, you will have to re-enter your clocks information, re-connect your phone and also set up your radio preset. This happens because the radio loses the constant power connection that it already had.
Fix: The fix for this is to re-enter all of the information to your stereo, this is normal operation.
In conclusion, don’t let a resetting car stereo ruin your music experience. With a little bit of knowledge and some troubleshooting, you can solve common car stereo problems without having to visit a repair center. Remember, your car’s music system is an essential piece of equipment, and knowing how to take care of it can help you enjoy great music on the road.
