Hi,
I have the above unit, and I've noticed the navi is out by about 50 feet all the time. I have checked and usually have about 12 satelites connected, I have move the antenna in better line of site, and reset the calibration, but make no difference. I have modified my location, but it soon goes out after 1 mile. The main problem is I keep missing my turns because when it says the turn, I am already past it. Will the ugrade to the map software solve this issue? Any suggestion? I have other sat navs and this one is the worst when it comes to accuracy.
Thanks
Koush
