Build date 12/26. Driving downtown Chicago also a block or so behind. Driving on the highway, at least 200-300 feet back. Sprint TeleNav is the worst, worse than google maps.

Here is another question:

I noted on my TP using any GPS program (live search, google maps, Sprint TeleNav), the motion of the car on the map is very jerky and discontinuous. I think this is the main source of the lag. Even on my wife's iphone with google maps, the motion is smooth and continuous, just like on my in car TomTom.

Any one can comment on their experience?

Thanks.
