I have a 2008 Prius. How can I find out which Navigation system I have and also how can I update the disc to the latest version without paying $200+ tax to the dealership? I really hate my dealership and have been avoiding them like a plague lately as all they do is steal money from me. I heard of people saying they download the torrent and write their own disk, which I would love to do, BUT I don't know which latest version would be compatible with my Nav System. Any suggestions would be greatly appreciated!
