Any wiring diagrams for Mylink NAV?

[rray]

I'm looking for any diagrams related to the interface between the 7" screen and the Mylink radio.

I want a better NAV radio, but want to use the Mylink touchscreen and button interface, as the current screen is very bright and readable, and I like the heating and air conditioning controls better than the Metra interface for aftermarket head units.

I have been scouring the web for the past 3 weeks, but nobody has attempted to hack into that screen yet.

What I want to do is pull the Radio module out, install an HDMI/RGB/AV interface board onto the Mylink screen, and interface the touchscreen to a PC based navigation radio.

I already built the replacement NAV unit, and it's features and sound quality are far superior to the Mylink, I just need the interface info or wiring diagrams to the video, touchscreen, and navigation buttons.

If interested in how I built my NAV, here is my Build Worklog. I had it installed in my 2012 1LT, and miss the sound quality and features of my own nav unit. I used the free Driveline software written by Clockwork at mp3car.com

I can run dual screens, and any screen can be projected onto the windshield in full color as a larger HUD display by simply mirror imaging the screen and sending to a dash mounted flat panel.

Here are some screenshots to give an idea of the features it has, and any screen can be customized with your own custom skin.


















Any help with diagrams is appreciated.
Thanks, Robert
