GPS locations lags true location
I had a similar lag with my TomTom 910 when placed in my center console. It also required a few seconds (30 seconds to a minute) to acquire a gps signal which prompted me to buy the external antenna. I just placed the antenna on the shelf behind the rear seat and the 910 now acquires a signal before I even get around to looking at it unless I'm in a parking deck.
Oh, and the lag went away as well. Even at 90 mph it shows me passing the on-off ramps when I actually pass them. I guessing the TomTom iPhone mount will help address the lag issue. Hopefully.
