I have a 2003 Hyundai Tiburon. I have an aftermarket radio in my car that has the capability to be hooked up to a rear view camera. I did not put it in, I also do not have a back up camera. It was done before I got the car. At first it was just a quirky thing, whenever I would turn on the headlights, the radio would switch to back up mode. I would turn the radio on and then off again and everything was fine. Then every once in a while the radio and clock would reset. I kept getting annoyed with that so I left the light switch on. (When i turn my car off the headlights turn off as well) Then it occasionally started resetting when i turned the car on. Now as I drive down the road and my car has been on for 20 min, half hour, the dashboard lights turn off and the clock and radio reset.
