I have a 2005 es 330 with the Nav System. (Latest DVD) Testing it in areas I know it is not been very accurate.
For example I was at the dealers and programmed it to take me to a Military site (Base Library) the shortest and quickest way (route I selected) is due south, of the dealers, about 5 miles. Leaving the dealers it took me South however in about 2 miles it said turn left. I of course ,did not and continued on a few blocks later it again said turn left. Again I ignored it.This was repeated at all of the intersections Upon arrival at the main gate it stated "make a legal U turn" I did not and after I was on the base it then directed me to Library
Another short case I programmed in a location and it took me down a state road towards the programmed location.(The location was about 3 miles on the SR.) On the way it told me to turn right (which was the entrance to a shopping Mall) I no sooner made the Rt.turn it then advised me to make a legal U turn. I did this when I returned to the state rd it told me to make a right turn. This put me back on my original course before I made the Rt. taking me to the destination.
I question how I can use this with any trust when I am in an area that I am unfamiliar with. I previously had a Garmin SP III which was very good. I regret investing in this option. Does anyone have like problems or solutions?
