I think they are meaning backlighting ...... it will dim it when your lights are on. Find a wire that is powered only when the lights are on, there is usually one going to the clock.

you can ground it anywhere on the chassis, i usually use bolts that gointo the fire wall when im working near it.

The blue wire you are talking about is if you are using a camera for when you back up. You don't need to use it you can just cap it off with a wire nut. The wire gets power when you go into reverse b/c the reverse lights come on. Then the TV will automatically switch over to the camera. That is why you have 2 sets up inputs on your TV. V1 and V2. 1 of them is for your source (DVD, Playstation, etc) and the other one is meant to be plugged into a camera.

ahhh .... finally somebody with the right answer. I have never had a monitor in the car, so I learned something.
