Audio Systems: Car audio video upgrade, honda pilot, wheel adapters

Question
I have a 2004 Honda Pilot EX-L- with DVD player. I want to upgrade the in-dash portion of the system to have a video screen as well, while keeping the same functionality of the controls. For example dual control, steering wheel control, options to continue listening to music up fronts while movie is playing in the back through head phones. I am looking at something like this XO Vision xod1737 7-inch Touch Screen DVD Player. I was just wondering if that would work in my car and if the installers would be able to keep the same functionality? I also wonder if an ipod could be connected to the system so it plays audio and video with that new setup? Any other suggestions for the upgrade are welcomed.

Answer
no that is not possible the features are part of the Honda radio,
there are steering wheel adapters but not for xo vision

our customers keep the factory radio and use this interface to  input audio from the ipod
