Toyota had a sale on the Nav upgrade DVD fopr $169.00 so I went out and bought one since the old one didn't have a lot of newer streets and addresses nor did it have my street. I'd heard some complaints that people liked the newer models of Prius since one doesn't have to touch the screen to enable the navigation. Well, the new DVD I just bought immediately jumps right into Nav mode without having to agree with Toyota safety concerns, it's really nice to have the newer POIs and addresses.:cheer2:
