Alright, wow lots of info here. Forgive me if I'm duplicating posts.

I'm basically looking for the best possible iPod setup I can get. Even if that means throwing in a whole damn CarPC (+1 for cool factor).

But if I were to go this root of a CarPC, would if be worth trying to use the stock NAV screen in my 07 Maxima, or toss a new screen in there? If I get a new screen (recommended in another post: https://xenarcdirect.com/product.php?productid=16136) could I then hook up my stock NAV back up to this as well?

Would I have to setup a switch to toggle the PC and NAV? Or is there a way to plugin my stock nav and access it thru the PC's software? Thanks!
