Anybody know how to/or know of a company that adapts the factory navigation unit to allow it to play regular DVD's?
I found tvandnav2go.com website, but you have to purchase a seperate DVD player

That's the only site I found too. It's like $250 just for the harness. I'll eventually get one but it seems like a lot of money for what it is. Especially since you need an external player, like you said.

you can play movies off of your ipod too
