Thanks for the input guys. I have just purchased an 05 navigator and It came from New York so it had a tv tuner instead of dvd player. I was imformed that all I need is a dvd player to hookup to the screens. The screens have power to them but no dvd player to send the signal. I was wondering what kind of dvd player I can put in the glove box or under the seat. I just thought you guys would have some input to my situation.
