So the radio and CD player suddenly stopped playing, even though it showed the CD as tracking. Then it suddenly began to work just after removing and replacing the 6-CD cartridge in the trunk. But now the radio always prompts me for the radio code, which I enter or just hit a button or just let it automatically start playing after about ten seconds.

How do I make it stop prompting me for the code every single time I turn the car on??

 

one wire goes to battery all the time which keeps the memory.

 

Sorry, but what does that mean? How do I get it to play normal without entering the code or hitting a button every single time?
