Hey guys, I bought the Alpine 9830 from crutchfield and it worked for about 4 months. Now, I can't get anything to come out of the speakers. When I put on the faceplate (I take it off when I'm not in the car) everything lights up and I see the sound meter go up and down and it raises my antenna but none of the buttons work. The volume knob doesn't work, source doesn't work, and the tilt doesn't respond. It seems like it is recieving an FM signal (b/c of the sound meter and raising antenna) but nothing will play through the speakers. Thanks for the help!
