I have a very odd problem. I picked up the car from the body shop (had it for 5 months when someone rear-ended me ) and the speakers were running static through them. This was as soon as I opened the door and without any key in the ignition. I then turned on the car and then the stereo and the static continues and I have a little bit of radio. Within minutes I have no radio and I have static coming mostly from the front drivers side dash speaker with an occasional pop and static from the passenger side front dash speaker. I went to the dealer and they are scratching their heads and can't get it in until Tuesday. On the drive home the static stopped for the most part but there is still no radio or CD sound. I suspect it is the head unit but has anyone ever had this happen before? This is in an 07 93 SS 2.0T with the Premium 150 stereo package.
