I'm in the process of traveling cross country so please excuse me if there is already a post about this. I noticed that the accuracy for my gps sucks when I'm on the road. I'm driving through Phoenix right now and the accuracy on my gps is over 9000 ft. My actual gps is picking up a fine signal, but the gps isn't really picking up a signal at all. Cell tower triangulation is even more accurate than what I'm currently getting. Anyone else have this problem, and anyone know anything that might help? Thanks.
