Yeah, yeah, I realize it's better just to buy a Pioneer or something and go that route. But I'm just curious if anyone's tried to get a deal on the factory nav after purchasing the car.
Not worth it... and most dealers probably would know how to do it correctly. You are way better off getting aftermarket from a good audio shop. Better and more features too, and you don't have to rely on the dealer to have up-to-date maps.
