2011 MDX Navi diag mode and real view camera hack

[pdprich]

While I'm trying to hack the HDD Navi systems on my new MDX I found few diagnostic feature that's build in to the systems.

Start the engine (for some reasons diag will not run when the engine is off)
At the OK screen hold the MAP/GUIDE MENU and CANCEL all at the same time for 3 to 4 second the systems will switch over to the diagnostic mode . you can check all the detail information and settings and run a self-diag mode. You will need the your anti-theft code.

The real view camera connector Pin 1 (black) is the NTSC signal.

After few weeks of messing around with the navi systems I was able to turn on the Real view camera by supplying 12volt (battery 14.4 voltage when engine running) to Pin number 22 (Brown wire) at the back of the LCD screen.

Here are some other pin information I found on the screen.
pin 11 (Wire color yellow)= Composite Blue
pin 12 (wire color white)= Composite Red
pin 24 (wire color red) = Composite Green
pin 23 (wire color green) = Composite sync (horizontal/vertical)
pin 25 (wire color black) = Composite ground
pin 14 (wire color black) = Real View Camera signal NTSC
pin 26 (wire color white) = real view camera power supply


Looks like there are many ways for us to tap into the 2011 MDX navi systems.

As of right now I'm able to install a switch with a SPDT relay and supply battery power to pin 22 to turn on the real view camera anytime I want .

My next step is to tap into the real view camera NTSC signal to play DVD movies on the navi systems.

Wow, keep up the good work, a lot of people want that camera working on demand.
Thanks

Good job on the screen wiring and I'm surprised that there are not more comments on your work.
I do have a couple of questions: How do you access the screen connector?
Where did you tap to get the 12v into pin 22?
BTW 11, 12 and 24 are the component inputs and 14 is the composite. (Composite and NTSC are the same).

Any detailed instructions available so I can try this?
