I decided to give the universal headrest screen setup a try. I bought them from Crutchfield. Going by all my Crutchfield catalogs, the Movies2Go package had an audio/video output to run to other screen(besides the two it comes with). Well come to find out, it does not have this(catalog misprint). Now, I can return the setup but I hate to. For the price, they are really pretty nice and blend in pretty well with my taupe interior.

The package comes with 2 headrest monitors, one with a dvd player built in and one without. They are a master and slave setup. What I am wanting to do is try and tap the video going out of the master headrest. The master has 2 cables going from it to the control or brain box. There are 8 pins in each cable for 16 total pins. The same cables run between each screen and the brain box. The master has the built in DVD player and also allows for an aux. input for audio and video via a 1/8" mini jack on the front panel. Using the all 16 pins, does this seem like it could be correct to account for all 16 pins?

My bottom line question is, does it seem possible to tap the video output from the master screen in the 8 pin cables and run to my Nav2TV? I may just have to start probing wires but wanted some thoughts first. Thanks.
