I have been reading these post trying to fix this problem. I had the same problem as sha. It turned out to be the same problem as lee roberts, a black wire going into the head unit was completely loose, after reading this post wasnt very hard to find, fixing i however was. it is something like a 24 gauge standed wire, and putting it back in the connector was no easy task. but I got it back in there, problem solved thanks guys.
