timothybeeler,
Thanks for your reply. I looked at the aftermarket option, and you're right. For under 1K, I can get a car computer with 9Gigs of computer space, a gps receiver with internal antenna, a touch screen monitor, and a guy in NYC can make a custom fit dash trim panel for about ~$100 bucks. I still wanna have the same set up as if it had a factory navigation unit. I believe this means I would only need a new ECU, and a/c vents. What else would I need?
