I just got my Z2 put in and love it. When I was putting it together I noticed the second plug on my factory head unit. My guess is that this is for the rear DVD system and controls.
Does anyone have the pin out diagram for this plug? Anyone figured out a way to make that stuff work with the Z2? I am thinking at the least I should be able to find the video signal input to make the rear screen show the dash display. Would be nice to get the rear controls to work too.
