My factory head unit in my plymouth neon has recently started to mess up. While I'm driving the time changes by itself, one time I was looking at the clock and it said 11:20 or something, adn then i saw it turn by itself to 12:20, 1:20, 2:20, and so on. And while I'm driving the radio changes channels by itself. It has memory on the preset stations though. The tape player is broken on it so it may be that the head unit itself is broken. It is connected to the factory wiring harness so no wires are mixed up. I am buying a new head unit, but what I am wondering is, is a fuse blown inside the car? or is there some other problem wiht my car. Any help or opinions would be great. Thanks, Jason
