Trek buddy. But needs some initial work to make maps.
Otherwise, a great app. That doesn't need internet at all.
Navigation is pretty good and above all it is completely free. Though it says beta, it is very stable and good to use and I used it on 3 or 4 higway trips. It might miss the occasional turns due to maps not completely updated but that is quite rare. Overall it is very dependable.Nokia HERE maps. You can download maps for individual states as required. It is quite detailed too. I haven't used the navigation part, so no comments on that.
