Thanks again everyone.
To Odimus, When you say dual zone I assume you mean separate functions for front and rear passengers at the same time. In the book it reads "this product's rear video output and rear audio output are for connection of a display to enable passengers in the rear seats to watch the dvd, etc." I would think that the front passengers would be able to listen to the radio while the rear passengers could watch and listen the a dvd at the same time but I do not know for certain. It may be something that 911jason could answer.
To 911jason, So far I have been able to figure out what I need as far as basic settings. If I get stuck trying to figure anything out I will definitely seek your help.
