Stock stereo is not working. It powers on, but there is no sound and nothing else works. It is on an FM station, but the tuner doesn't work, the pre-sets don't work, and mode buttons won't work - I plugged in my mp3 player and it switched to AUX but nothing - no sound.
I have re-set it by disconnecting the battery and entering the radio code - but still nothing. I also checked the fuse and it was fine. It is like the lights are on but nobody's home!

Please Help!

 

I think the later models have a separate amplifier unit between the head unit and the speakers. The amplifier also has its own fuse.

 

Thanks! I will check that - would a blown amp fuse cause the other problems besides the sound?
