I have a 2006 Prius, Package 6 and was wondering if Toyota markets an after market add-on that once installed would function like the factory installed units. Though the screen looks identical to those with the factory Nav, and the steering wheel has a "Map" button, some of the buttons on the factory system around the screen are not present. Anyone have any information on this? Thanks in advance...
Toyota does not sell an aftermarket NAV. Just get yourself a Garmin, Tom-Tom, or one of the others. You'll be just as happy with it and updates are a lot cheaper.
