Best Buy did, the guy was baffled, he was thinking something was wrong with head unit, but it was working perfectly fine when it was removed an hour before?! I am suppose to go back Thursday to let him look at it again. Yea it has a reset button, I tried that but it didn't do anything. I was there watching him remove and install it, didn't notice him drop it or something. Granted, I should have said something but I haven't installed car audio stuff in 9 years, he didn't disconnect the battery when he was doing the installation. When I was leaving, I noticed my dash lights weren't working anymore, brought it back in, the fuse had blown. I am thinking maybe the fuse is blown or damaged on the head unit, maybe not able to put strong enough signal
