Hi.. all.. this is my first post .. friend of mine just a bought a 2007 camry v6 xle with indash nav. He wanted to know if it's possible to watch a movie dvd through navigation dvdrom unit on the screen .. I think he tried putting a movie dvd on player and did not work .. just wondering if there is anyway to full nav dvd player like creating a dvd similar to nav dvd structure and playing or any hacks for this solution...Thanks... or you can lead me some info more on this topic for extra reading,I'll appreciate that.

I know with my cruiser you can watch a dvd through the nav system if the car is in park with the emegency brake on but not while it's in gear. I also am trying to figure out how to overide the system.
