So i am thinking about adding two seven inch screens in my seats and had a few questions. first i will be using my avic z2 as the dvd player on the output, will i be able to have the kids watching a dvd in the back on headphones and radio through the speakers in truck? if not what will i need to do to make that happen? any help would be great thanks.

i know that the newer Z's has dual zone (listen to different thing front and back) but im not sure if all of the older models have it or not

Ok I guess I will try to find out more info on my unit thanks for reply

My Z1 has dual zone. Your best resource here is the user's manual. It will explain it and how to set it up.
