About 50% of the time when I start my truck, the radio doesn’t work. The blue tooth and camera work, but the radio doesn’t play. I have turned the key off and back on but that doesn’t work. I have tried turning the engine off and locking and unlocking the doors but that doesn’t work. The next time I start the engine, it works just fine. Could it be a sticking door switch that turns it off when you open the door?
