We recently took deliver on a new 2004 Prius with option 9. I am most disapointed with the Nav system. (I own other GPS systems from Magellan, Delorme and Garmin) The Toyota/Denso system only seems to be able to provide city to city assistance with a very poor street level to street level routing. Frequently, it does not start at street address (shows map and "prompts" you use closest roads to get to start point) and ends sometimes miles from the destination street address) and again "prompts" you use map screen to nav by best possible method.
I have never had such a low level of routing detail calculations! I have written the vendor that supplied Toyota with the maping software and was assured that using the same database software, other brands of Nav Systems are able to provide instructions to the street level ! They suggested that "if the system only works to the level of major roads, it must be something in the Nav systems algorithm for ploting route.
I had my dealer try a few addresses on another Toyota vehicle (not Prius) and he had the same result, yet to date, Toyota USA has no answer for this glaring deficiency in what is otherwise a wonderfully high-tech car!
We love the car, but compared to my Garmin Streetfinder III, the Prius Nav system about 5 years behind the competition.
Has anyone else had similar observations and if you reported same, what was the outcome?
