I'm not familiar with the year by year changes in the Armada, but TVandNAv2go.com or AVelectronic.com both have modules that allow you to input an external video signal to the Nav screen. I haven't looked at their products in a while, but you would likely need a video splitter with amplifier as well. The stock DVD's signal is too weak to display on 2 screens from the same signal. I have an AVelectronic unit and it required an amplifier.
I'm not sure how you would wire the CD-DVD button to activate it though as I don't have that in my Titan and even then, its likely a momentary signal when depressed. Adding a module that accepts such a signal can work but can also be glitchy if for whatever reason the input device and the screen's input setting are not synchonized (DVD player on, screen is displaying Nav and vice versa). I can't recall seeing a static signal from the DVD player that you might be able to use either. You'll probably just need to wire in a manual switch. If you have no need for the Nav programming ability while driving, then you can use the aformentioned KP technology device to bypass the disclaimer screen and use the "OK" button switching funtion to toggle between the Nav and DVD display.
