I think the reason my backup camera is staying on is due to the unit thinking the rv is still in reverse . I have a 2016 Miramar 34.3 does anyone know where this switch is on the motorhome . when I shut off the engine the screen on the radio unit has a message that camera 'A' signal is not found . When the rv is running the backup camera stays on . I thought I noticed the back up lights on the rv on when I had the lights on but I need to verify that .
