Might be a dumb question, but is there any way to tap into the Nav system monitor with another source like DVD, VCP, or laptop? Just curious if anyone has played with the factory monitors at all. I wonder if there would be a way to make a wiring kit/instruction that could add video input. I am sure that the monitor is not made for optimum resolution (similar to the first alpine nav monitors) but sure would be cool...idea sparked from the post about adding cameras to the car. hmmmm
