Trust Us to Use the Navigation System!
 My husband and I love the Prius we have.  The only issue (and it is completely unacceptable) is that Toyota does not trust the driver (or the passenger) to use the navigation system safely while the car is moving.  Either restore the 2005 and previous override or only disable the nav system if no one is in the passenger seat.  If we had known what limited functionality the navigation system provides while you are actually enroute, we would not have bought it!
