Prius Navigation System- It sucks.

My 2008 Prius can't find my home that has been here since 1979. It shows my home one block away.

The databases do not identify specific addresses. They are based on a range of addresses for a given block or a stretch of road. In more rural areas actual house numbers may not be distributed in the same uniform manor as a mapping program does.

All mapping programs experience this kind of anomaly to one degree or another.

Where does Google Earth show your house? If you enter in your address in the search box, I'm willing to bet it's at least a house or two away from where it really is.

Sorry, I should have posted in a 2010 Prius thread - it is now there.

My 2009 gets me right to the driveway of my house, also built in 1979. How it gets me there is another story

I too have a 2004. When I pay premium dollars and supplement that cost with an additional warranty, I harobr a reasonable expectation that this product will function as agreed. I have an issue with the Intersection function on the Nav system. It just does not recognize 95% of the intersections. I use this function in my work and I have to carry around my hand held Garmin. I know it’s a program flaw, but I paid for this product to function with a reasonable degree of accuracy. Before you folks who carry the water for Toyota go off into your tangents, just remember, I simply paid for a product and expect it to work. If my $300 hand held GPS has the intersections, why can’t my $650 GPS give me at least 20%? Is that too much to expect? sandoval10@sbcglobal.net. I welcome emails.

Kinda retarded how people depend on their navi 100%. Have you guys read about how some old lady drove off the road because her navi told her to? Navi's are used as references. New streets and so forth will be built etc. You have to use your brain and eyes along with the suggestion of the navi to get home. If you are using just the navi then you have issues. If your address is off, add the gps cordinates into the system so that the system can take you there next time and not the wrong way. I'm pretty sure no gps mappers went to each individual home to map their proper cordinates. So man up and quit bitching.

Have you tried updating the Navi info disk? My `04 had the original disk when I got it this summer and it was terrible too. A new Navi disk seems to have solved my issues.

Do you think getting an updated NAV disk may help since if it's original there must be an update for your system? I bet that could help a lot in your given situation. Just a thought.

In my 09 Prius, the Nav is a piece of crap. Mine has all the problems mentioned plus some special ones of it's very own. But I solved all that by getting my old Garmin Street Pilot out of the closet. Even though it's 3 or 4 years older, it's far more accurate and far more intuitive. No, it's not perfect, but it's not crazy as is the Denso. But, hey, the nav is the only thing about my Prius that I don't like and my old Garmin has solved that problem. I'm not going to waste my time worrying about having been cheated or that I wasted money or that Toyota is incompetent on occasion. They can't be happy about this situation either. I'm happy to let it be their problem.
