Check all you interior harness's. check ecu harness. something has come loose or short out. Its going to be a real pain but the best way to do it is look at easy stuff first. If it consistantly does it when you turn on the radio, then start there. remove the radio. atleast you can narrow it further. If it is coincidence, check all the harness behind the radio. good luck. And if you are really not getting anywhere we have an awesome wiring guy here. we will be able to figure it out.
