After my first experience driving a 2005 Navigator I decided to get one soon. Hopefully in another two months. I want to be able to play DVDs on the navigation screen as well. I found this site http://www.tvandnav2go.com/ford-navigation-system.html that says you can mod the navigation system to play DVD's and still retain all the functionality of it. Here is another site as well http://www.logjamelectronics.com/pacvcifrd1.html. Search google and you will find more as well.
