i agree with BG-8. you should just get a car without the nav and get a metra double din kit. then get a nav/mp3/dvd/cd thing for like 700 bucks or so. the total for all this should b less than a thousand or around there. It is a way better way to go than with the oem nav, looks better too imho. if u decide to in the future you'll also have that space where the oem nav would go to put some gauges up.

I dont mind having a different nav system ... i just want that OEM flip up screen cause it looks neater lol
