I went into the gym and when I came back I can't turn my volume up or down and of course it's set as low as it can go so I can't hear anything at all. It was working fine when I went into the gym so I don't know the deal. I have on 06 ls with stock headunit, the one with 2 different knobs on the left and right. Has this happened to anyone else and is there a way to fix it? I don't want to wait a week to take it to the dealership just to fix the radio, plus I'm at 36,347 miles so I'm not covered by warranty for it I don't think (I'm sure GM doesn't time these things to happen )

I also know this is the wrong section but I was hoping to get a reply in a resonable amount of time before I leave. Sorry.
