So tonight I had Hells Bells playing at about 30 (hey it's hard to hear the music at 90 with the windows down). Anyway I stopped for awhile and when I got back in, no sound at all, either from the HDD or when I slid in a CD. Even though it looked like the CD was playing on the elapsed time deal on the screen. Finally went to the back and pulled the 3 fuses that I think are for the audio but none of them were blown. Put them back in and when I got back in the car bingo everything was OK. Anybody know what happened?
