Would anyone have an idea why a radio playing will start on its own? Mine comes on when the the Rover is sitting in the driveway not running? This happens every once in a while. I start the rover and turn it off and the radio turns off and stays off for weeks. I ahve checked the fuse for both the radio and the amp. Both are ok. Its a 1999 with 155,000 miles. I believe it is the orginal radio. Also at times non of the buttons work and then they start working. The knob does nothing as far turning off and on or controls the volume.
