Hi all excuse me i am having a strange issue i have a BMW E46 TV CD Monitor which appears to be faulty. I installed it in my car it worked fine. But when i removed it to installed it into another car it wouldn't power up. So i tried it in my car again the same thing no power. What could be wrong with it can anyone tell me please? Here's an image of it when it was working in my car.
