So i searched on here and kinda came up emptyhanded. Im parting my 06...or raping it before i trade it lol, someone with an 04 wants the factory navi, and i was wondering if its a plug and play, or a huge pita! Thanks!

 

Don't do it. You cannot install the factory navigation in a car not already wired for this. And, even if the wioring is in place, the '06 isn't compatible with the '04.
