I have a 2000 audi tt. The stereo was working perfectly until i had to remove it to change the flasher unit, ever since then i've had problems with it. I finally got the stereo to come on but heard nothing but static out of the driver side speaker. The static noise was getting old fast so i decided to take it back out to see what the problem was couldnt find anything wrong so i put it back in and now i cant get anything out of it....wont even power on. The fuse on the back of the radio is fine. Any ideas on what the problem could be?!
