Im going to go thorugh Mattjk and get his screen set up, but I already have a CD player that I spent too much on (unfortunately doesnt have dvd capability). So if I go the cheaper "portable dvd player in glovebox" route will everything operate through the dvd player or my cd player (for audio Cd's). Having to put all cd's in the dvd glove box would be a pain. Has anyone gone this route? how does it all hook up? pics?
