GT3

That's right. this may be a dumb question, but do I insert the movie DVD in the Nav unit under the seat (and not the CD ChangeR)? I haven't tried yet only because I don;'to mess anything up and I'm a rookie when it comes to in-car entertainment systems

Yes I have the ML system. The disc changer only plays CD's as far as I can tell. My Nav screen does not show an option for video either. I put a DVD in the changer, but it could not read it. Am I missing something?

Just bought a 2006 GX Sport. I'm trying to figure out how to watch DVD movies on the nav screen. I do not have the 2nd row DVD option. Any help is much apreciated!
