Just about everytime I start my car, my stereo resets itself back to factory defaults, all the preset stations go and when powered on I get 87.5 fm, or if cd is in, it plays first track. Its getting quite painfull, have to adjust the base again and reprogram my stations only to lose them, now I dont even bother.
Its like my battery is disconnected but its not, recently had a problem with a fuse held in by lose contacts, turned out to be the fuse powering cigar socket and stereo. Sorted that out but still the factory resets. Always happens when I start the car. Possible the battery is bad and not keeping the +12v on yellow wire to back of stereo?
