I've got a problem with my new headunit. I've just finished installing this HU this afternoon and thought finally, a new HU. I set up my preset FM channels, set the time, fixed the equalizer, and everything works, ALMOST perfectly... Now, here's the problem. When I turn off my car and turn it on again, my HU is resetted to its factory settings. Time is back to 1:00. Equalizer is back on default, everything.. and even my preset channels are gone.... It only happens when i turn off my car and maybe* when i take the face off.. or both?. Anyone know whats the problem and how to fix this? btw, this is brand new from Best Buy.
