To clarify, I didn't have to do any mods to bypass. The original poster is asking if the car is parked and parking brake on, can he watch dvd's on the front screen. In my 2008, this is possible with a stock configuration. Although I have since added a bypass, I know for a fact this worked pre-mod. Just asking if this didn't work pre-2008? I don't understand why they wouldn't allow you to display on the front screen when parked and parking brake engaged.
