ive had an f90bt in my car for about 6-7 months now, and its worked fine all along. however, lately something screwy has been going on. i noticed it the other day, it froze up while playing a song, and when i tried to advance it to the next song it restarted. after that it worked ok.

last night, i had the volume all the way down so idk what the music was doing, but i was looking at my speed. i was going about 83, and the GPS aggreed. then it sped up to like 95, then dropped down to the 70's. then restarted. no matter what i tried, it just *kept* restarting constantly. so for an hour i watched the thing flash like a christmas tree. i shut my car off for like 2 minutes when i got home, and after i restarted the unit it worked fine. i went to go out today, and it was still working OK, until i started moving. so my ride consists of listening to music at stoplights, and listning to rattles and creaks while moving. any ideas??
