So I just purchased my first MB. I love the car but it has 1 annoying problem and i can not for the life of me figure out why. So if the car is running and I have to open the door (could be running in park, sitting in gear with my foot on the brake or anytime the radio is playing) the radio shuts off, folds itself into the dash and turns off....then turns back on, unfolds itself out of the dash and goes back to working just as it should. This happens when you open either front door. I haven't tried on the rear doors yet but both front do it every time. Any help would be greatly appreciated!

 

Bizarre...any aftermarket Blue Tooth, rear camera, alarm, electronics ? If door is open and radio OFF, what happens when you turn the radio ON ?
