I have a weird issue in that this seems to lag behind hte actual position of the car. I just wanted to ask if others have this issue. When I use GPS in MS S&T it is right about on where I am at the time. When I use WW it is slightly behind, but google earth is like a block behind when I am only going 40mph. It also seems that update thing does nothing to ameliorate the problem. In fact it seems as though a refresh of 2 seconds is no better than 5. Is there a minimum time for updates or something?
