I know you all are gonna tell me I posted in the wrong section and that there is a search. Well I searched all day today before posting this. Question I have a 07 factory nav system can I play or watch a DVD with this system. When I plug in my iPhone it says entertainment system enabled. I have a DVD screen for the kid that I tried to plug in I could get sound but no video. I am thinking its a no go on this but I have to ask. I did try the unlock disable tonight just to get the gauges.

 

If I remember correctly, the DVD function only operates while the truck is in Park. As far as plugging in additional devices, I don't know what effect that has on the NAV, concerning playback on either the main screen or device screens, sorry.
