I have a Range Rover sport 2006 s/c and the TV doesn't work when the vehicle is running or even with the key in the on position, but it works fine when the car is turned off or when the key is in the accessory position. It says "the picture is disabled when the vehicle is in motion for your safety," but the car is either just in the on position(engine turned off in park) or is just idling in park.

 

I also have a 06 s/c with the same issue. I have not figured out a solution yet either.
anyone else have the same experience, or a solution?
