I have done some searching and I see the 08 hack but I havent been very successful with previous years. I see that tvandnav2go is a solid option. Is it the only option or the best option?

Also, can you plug external video/audio into the DVD changer via the external rca's? I ask this because the tvandnav2go has two vid inputs but you could technically have 3 using the external rca's on the DVD changer right?

How do you get audio from DVD changer to an fm modulator? Is there a way to bypass the fm modulator?
