Hey, has anyone had any experience with upgrading from the hard drive-based to DVD-based navigation, dealing with both the drives and screens? I'm thinking I might want to switch to DVD so I can get more up-to-date maps. I looked at pictures of both the HD and DVD drives and the plugs look the same. Idk about what the screen would be like. Any insight?

 

There is already a forum on that.

 

Oh, could someone link it? I'm having a hard time find it. :S
