hey guys, I'm new to the board and I recently received a 2000 lincoln navigator. I am planning on installing an overhead flip down lcd, as mine did not come with one. What I'm wondering, is how I would go about installing one. I've been thinking that the easiest way, would be to remove the headliner so I can see where the vents are for the overhead ac/heat, and also so i could see where I could possibly attach it to. Any idea on how to remove the headliner, or any easier way to install the lcd? thanks
