Malfunctioned Memory Wire
If your car stereo keeps falling back to the default setting whenever you start the engine, it also might be due to a malfunctioned memory wire.
A memory wire is a yellow-colored lead in your stereo’s wire harness. It is different from other head unit wires because it contains power all the time, even when your car is standing stationary with its engine off.
This wire provides power to the clock of the head unit and the radio frequency setter. It is called a “memory” wire because it saves the station (radio frequency) memory and plays the same frequency that you set the last time whenever you turn on the stereo again.
If the reset happens primarily when you start your car, you should try replacing the memory wire and see if the problem goes away. If you can’t detect any issue with the memory with a visual inspection, check it for its voltage reading through a multi-meter. A perfectly working memory wire will give you approximately 12V reading when the engine is off.

It’s a sign that your head unit has developed some internal circuitry issues. You have to consult an expert audio enthusiast to resolve this complex head unit issue. In some cases, you might have to replace the head unit altogether.
However, always make the final call regarding the head unit replacement when you are 100% confident about its irreparable malfunctioning. Car head unit replacement is an expensive affair and might require extensive work. Therefore, due diligence is very important before declaring it broken and replacing it.
