I was looking at getting an aftermarket overhead dvd player for my 2005 F150. I have the rail system and the wiring for a player but I don't want to pay an arm and a leg for the factory system.

Who has installed an aftermarket system and how did you mount it to the ceiling? Also what's the best way to connect for power? The one I'm looking at has 1 output so I may connect it to my Sony 7715 headunit via aux. input. How does that sound?
