First time this has happened to me. Had the truck for a year and a half. Was in it all morning, everything normal. Got back in it after lunch, radio full volume with no control, no response on the screen. Turn the knob really fast would get it down, but would return to full volume on its on. Shut the truck off several times, no change. I recently replaced the starter, matter of fact, the day before this incident. The radio has done some other funkie things on its own, but not this. I thought the speakers were gonna blow. Any suggestions??
