Replying to: rtribble (Mar 24, 2008 7:18 am) It should be automatic. Don't think there is any calibration. The NAV uses a combination of global position triangulation via overhead satellites, in conjuction with wheel speed and gyro sensors on board.

Well ours gets lost and the only way I can get it back is to take the car to a known address and manualy take the nav there, orien the car to that known location and then re-calibrate the nav through the set up menue. Of course this won't work if you don't know your exact location to start with. In reading the manual, I was also under the impresion that the nave would re-calibrate it's self if you were to turn it off and then back on. But once ours gets lost it stays lost untill I manualy re-calibrate it as mentioned above. Do you think our nav is defective or have I missed something that should have been programed?

Replying to: rtribble (Mar 26, 2008 5:59 pm) rtribble....Do you live in a mountainous area or large city where sat reception might be poor? This could result in the Nav not being able to position itself if it doesn't have clear "sight" to at least 3 satellites. I've not had any issue with the accuracy of the unit in my 08 Sequoia and have actually been somewhat pleased with the nav unit overall and more then I was expecting based on my experience with my Avalon Nav unit.   Of course, I'm mostly satisfied with the unit because I added Wilee's aftermarket Nav Pulse Generator which allows me to add destinations and use the phone book for BT calls without having to stop the vehicle. If it wasn't for this device I would have probably wanted to throw the Nav unit out the window by now. With this neat device I actually like the new Nav unit in the 08 Sequoia. Not as much as my Garmin, but not nearly as bad as I was expecting.   Here's a link to the Nav Pulse Generator http://www.pinemountainfirearms.com/pmf/tundramods/NavSpeedPulse.aspx  With just a little competence in making wire connections it was actually a rather easy install.

hdftboy, We live in Oklahoma. As long as I stay on the main roadways ours works pretty good, but if you get off and drive around on lesser roads or large parking lots it will get lost pretty easy. It will self correct for small deviations but if it gets turned around or off by very much you have to stop and manually bring it back where it's tracking right on the map. I you get too far off it will not self correct it's self but will continue to get further off track. Reading the manual I believe that It is supposed to allow you to manually instruct it to re-calibrate it's self to your current position and it is supposed to automatically do this after you hit the icon on the screen. I've done this after taking the car home and orienting the car to the "home" destination and it works fine. I've not yet tried to do this while the car is not home and still lost somewhere on the map. I'll have to try this and see if it will work. But even if it does work it is still a pain in the butt to have to stop the car and go through all that when I thought the car was supposed to do this automatically. I've down loaded the pulse generator installation earlier but it loks pretty involved, especialy for someone who doesn't even know how to work the nav system yet, but mabe latter after I have learned more about it all. Thanks hdfatboy. Replies to this message: rtribble (Sep 18, 2009 7:52 am)

Replying to: rtribble (Mar 27, 2008 4:55 pm) This is an update to my earlier posts on this suject back in 2008. Our nav system continues to get lost almost evertime we go somewhere. It does seem to work better in the main cities but still will end up lost eventually. Recently it has taken to "jumping" off our actual position while driving down a main highway with no other roadways near where our current position was at the time and once it "jumped" off our position while sitting stoped at a red light. The thing just seems to have a mind of it's own and goes off in never-never land anytime it feels like it. As it is, it is completly ussless and we cannot depend on it. Other than the sorry nave system, we do love our Sequoia.
