I recently purchased a new LX470. Anyways, when I put in a DVD to play, I would only receive picture when the car is at a complete stop and the hand brake is on. I would like to get a way to get picture when the car is in motion. In other words, I would like to disable this security feature. The sale guy said you can "cut the wire", but I didn't ask him further. Just wondering if any of you guys had a thought.
