If you're talking about an in-dash monitor then you probably need to go buy a mounting or dash kit from any car stereo place including best buy or circuit city. This will allow for the din-sized radio to fit in a din and a half or double din slot.
How does the sound from your DVD player to your car speakers. If they do hook up with your car speakers than its easy all you need is a line out converter which takes signal from your coax speakers and turns it into a rca out put . if its just headsets in the car good luck. sorry nothing you can do if it doesn't connect with your car speakers.
Idling a car uses a moderate amount of gasoline and depending on the idle speed, it may not produce enough power to charge the battery since it is taking some power to run the engine. Pumping the engine wastes gas. A 60 amp hour battery will run down far enough that it won't start the car if you pull an amp for about 40 hours. If you are comfortable, you probably have no risk running the DVD for a movie with the engine off.
