it says in the specs for dual zone audio video allows you to enjoy 2 totally different types of media between the front of the car and the back. while you are listening to a radio station in the front and the kids are watching a DVD in the back while listening through headphones.

my question is the headphone listening capibilty for the back of the car through headphones is it wireless or does it have to be hard wiried, if it s wireless then does pioneer sell the headphones or who does

I believe the rear seat audio would come through the rear monitors.

You can get wireless headphones, either infrared or RF. They basically have a little base station that you run the rear audio output from the Z2 and it then sends the sound to the headphones. Pioneer and dozens of other companies make them
