There seems to be a lot of confusion and frustration in understanding and using the DVD Navigation System in the Prius. Granted, the Navigation Manual that comes with the car is not very well written or user friendly. I have found a video demo link on the Toyota.com web site that is very helpful in explaining, understanding and using the Navigation System. Toyota Prius Features This link provides helpful Tabs including an Introduction to the Navigation System, guides you through all of the Basics of the system, and finally, a "How to" Tab for a step by step procedure in performing all of the NAV functions. One of the biggest benefits I have found is the section on verbally inputing destination addresses while driving the car. Seems many here on PC think address inputs cannot be done while in a moving car. Not true!!!! If many here find this as helpful as I have, maybe we need to add the link as a sticky in our Information Database.
