TNR pinouts needed????

[spmiz]

Gang let me start by saying I love this group, it has some of the most informative info around. I just recently bought a 2005 Trailblazer with Touchscreen Navigation Radio and Rear entertainment system. It happens to be the same TNR that the Hummer has.

I am wondering if anyone has a diagram denoting the pinouts for the TNR?

I am also wondering whish signals are responsible for both no DVD playback and disabling changing of NAV system when above 8 MPH.

I have heard that when you have a RES and NAV that you can display on both the rear monitor and Nav screen.

Thanks for any help you can provide.
