780 works fairly well. A little quirky here and there but gets the job done.Just finished a 1,400 mile RV trip. It helps quite a bit but I would not rely on it 100% Check out your route on other mapping sites just to have a backup.
Helps keep the arguments to a minimum when driving with your spouse!
