    Just remember, if you are unsatisfied with the usability of your nav system, there is another step. Its called 3rd party arbitration. Its done by an independent party. If their findings are that the device doesnt function as it should they can force toyota to reimburse you for the full purchase price, minus a fee for the mileage put on the car. I had it figured at 25,000 miles and they would remove 6,000 off the purchase price. My car has really been driven and I have about 23,000 miles on it. Toyota is then responsible to pay off the rest owed on the car. That number in California listed on their web site will send you the necessary paperwork to start the process. I guess its sort of a shame to have to go this far about an issue that actually would be fixable if toyota would address it. But I have been told that this is the only way to get them to address it. That is really a shame. But what the heck, They got me for 34,000 for the car new, including my trade. knock 6,000 off for high mileage, I think that leaves me with about 28,000. With all the bad press, I know I can buy a new one without nav and have money left over. They dont want to give anyone the option of talking to them directly. So that sort of leaves me out in the cold for anything . I really dont want toyota to go thru all this.Hell I dont want to go thru it. I just want a problem addressed and solved. The one thing I think is pitiful is the fact that the same nav system is being sold unchanged in all the 2011's. The 10.1 disk has more streets supposedly and more POI's , but the system is still just as flawed. The same system is used in all models. I just hope we can reach out to their perspective customers and get them to read the "fine print" about the nav, and to try it out before they spend the money on it. I am willing to bet that most folks will feel better with the 2500 in their pockets and a 200 GPS suctioned cupped to their windows. Just think for that same 200 i can get an update to mine with more streets and points of interest I cant find. For the 200 for the portable one, i can chuck the old one in the trash and get a new one with better features. Well I know I already made my mistake. Lets do our best to not let others follow my lead. After trying it and reading the fine print etc, you perspective owners say good enough, please dont let me stand in your way of buying it. The best trial I think is put in your home address and see how close it get you to your driveway. My address is as I have stated before in a canal at the end of my street. The address it say I am at doesnt even exist. Lots of folks dont really care if it gets them to the exact address or not. I will tell you that it will get you to the right road. You just wont know if you went too far or not quite far enough. So if you dont use any country roads, know exactly what parts of the citys not to drive in. Always know where you are going or at least what it should look like, this may be the perfect GPS for you

    I don't believe my GPS is accurate for any destination. I get the "you arrived" message & the off button at my destination. Even though I press the button before turning off the car I have to turn it off again when I start up. I believe the cause is the crap addressing.

    The car's physical location appears to be accurate. My street address is 3307 & this is what I set for the HOME button. While parked in my driveway I poked around in the settings & found that the retarded nav unit believes I am at a much higher address which in theory I would have passed so my home is believed to be further down the street. (I'm going to drive far enough someday to see where it thinks I live.) I tried changing the calibration but it hasn't solved the double button press problem & added a satellite lock delay before it starts tracking.

    I've visited the dealer twice complaining unofficially. They try to help. Next time I'm there for scheduled maintenance I need to remember to complain officially.

    The only way Toyota is going to care enough to fix the problem is if they realize they are losing sales because of it. Fat chance of that happening.

    I'd be interested in knowing if a case goes to arbitration & the outcome.

    That is a common problem with GPS map data bases. Toyota isn't going to fix it because it's out of their hands. If you can designate "Home" as where you car actually is, set Home as your driveway while you are parked there, not at your numerical address.

    If I understood you correctly, you did a calibrate based on street address. Don't do that, use an intersection or other know physical point.

    I completely agree with you regarding your feelings about the NAV. It is not a product that is typical of what Toyota/Lexus would release for their automobiles. I am not happy with it, and as I have posted a number of times my $250.00 Garmin with free traffic blows away the Toyota factory NAV option. Sad, as the interface and display are good for me. Functionality however is very poor.

    For what it's worth, several months ago I completed a J.D.Powers survey on the Toyota Prius factory NAV. It would appear as though Toyota is having a vendor collect opinions about their factory NAV. I tore it apart in the survey. More than likely 2010 owners won't see any change as Toyota already got their money.

    Yesterday I did some tracking with the nav. The physical location of the car appears to be accurate. When parked in the driveway it believes the address is 3325 (5 houses "behind".) The unit believes 3307 is 3 houses "ahead". Now I understand why the OFF button needs to be pushed twice. The geographic coordinates are closer. The Nav's figures are 1 house "ahead" according to Google.

    I cleared the previous HOME setting then set it using the current position (sitting in the driveway). I'll see what happens Monday.

    Using this method to change the presets may be good for known destinations but rather useless for the nav's intended purpose. Looks like it's time to run the old Garmin as well in unfamiliar territory.

    JD Powers may be doing the survey for Toyota or they may be doing the nav survey to sell to everyone.

    Rather than complain about the Nav system over and over and over again, why don't we do something about it. First, I am pretty sure that the data being used is Navteq. I have compared addresses at their website with what I see on my Nav system and they are consistent. There is a way to request changes on their website and I suggest that for the time it takes to gripe about this, we go to the Navteq website and request fixes. The location of my house is way off on a realtively new street. But it's way off on Google maps too. So I have submitted requests for changes on both. It may not help but it definitely won't hurt. So let's help each other out by submitting changes as we find them.

    How does this "change" get from the Navteq web site or database to our nav units which are run off the Disc in the radio? Unless you upgrade for too much money?

    That sounds like a good idea in case you forget where you live. But how do I physically calibrate to an address before I get to it? Not trying to be sarcastic, just would like to get a fix to the problem. Tried your idea of calibrating to a physical point. It still is off on the numbering. It always knows where i am on a road, just way off on addresses. A guy from Autoway Toyota actually told me it was done as a safety issue. Keeps folks from doing the bad things that folks do with GPS's. Unfortunately he couldnt elaborate. The only bad thing I can think of is it getting me to my address safely and not get me killed in rush hour traffic while i try to read 4" high house numbers at 30 miles an hour or more.

    Were the Toyota dealers guys lips moving? If they were.....

    AFAIK, all nav system data bases have problems, often in different places.

    I know that doesn't help you, but don't expect Toyota to fix it. The database in the Toyota nav is shared by many different brands of nav system and it's not in Toyotas hands.

    Well I definitely found out it is a data issue. had trouble with the blue-tooth clarity in my car. Took it to the dealer and there was a service advisory on the issue. The radio, nav, and blue-tooth are the same unit. They were manufactured by the radio manufacturer. They did replace the radio, after it came into stock. I now live 2 houses closer to my actual house with the new unit. They used the same disk. So that has to be where the problem lies.
    I give up. Sorry to say that but I do. Heck I even went as far to try to call the factory in Japan. NO phone numbers were listed. Tried JD Powers, no luck. Guess they just give out awards. Tried TelaAtlas. It all has been a complete waste of time. No one seems to care as long as the cars are being sold. Hate to say this is probably my last toyota, over the years I have had 5 or 6 of them, all purchased new. Have had the car about 16 months and have about 27000 miles on it. Explains why I trade so often. I figure in a few short years American car makers will be equal or better on gas mileage. I warned folks buying new toyotas to not buy the nav, but doubt any of them will be reading any of these posts till after the purchase. Try before you buy. Wish I had. The other advantage is with all the corn we are putting in our fuel, all American cars will be flex fuel if they aren't already. I don't think foreign manufactures even look at that.
    Well its been fun. If anyone hears of any breakthroughs drop me a note. I still find it hard to believe the same navs are being put in the new cars with just an updated disk that covers more streets. This is a crime.
    Good luck to all.

    I've been down this road too, however not as far as you. I live at addres 54. Google Maps, Navteq, Mapquest and my Prius place me at 188. So my street is mapped wrong. Now I have found that when you are stopped in your Prius, you can press the map button and it will show you the address of where you are. I will say that in most cases it is pretty much spot on. However the Verizon NAV system in my phone places my address correctly so clearly, I can see why this is so maddening.
