Re: Headunit turns on and off while driving
Definitely sounds like bad ground and possibly dirty power source. Why I mean by dirty power is a wire that has hum, noise or intermittent connection. Sometimes it will throw the computer for a loop and make all kinds of errors, shutting off, etc. Start with the ground first. if that doesn't help, use a new power wire from the battery or known clean accessory feed.
