I just purchassed a 2012 Prius, love it but the manual that came with it for navigation is only a quick reference book, don't they make one that tells you everything about the navigation? Prius owners ROCK!... Thanks to anyone that can help me out. Dealership said thats all that comes with it.
Use this link and go the the navigation manual section. It is a link to Toyota's online manual. By the way, the navigation manual that came with my 2012 Prius is like 300 pages. Not sure what you got. Toyota Online Owners Manuals and Service Manuals
Mine is fairly comprehensive, but the images of the screen are completely out of date. Many of the things it says that you can access simply aren't there, and there are others that aren't in the book.
