Not the best routing on 710 model
Will take me on tight streets when there are wider truck friendly roads. When i am at an intersection gps says intersection is 100 feet ahead. It took me over a low weight bridge. It keeps telling me i have worked ten hours and need to take break and there is no way to stop it feom blocking screen until you close message screen. It gets confused in baltimore md also.
But atleast it will route you if you dont have time to check map before trip.
GPS is never perfect so map is still necessary.
