When I am driving, I let my wife operate Waze on her phone. I don't like looking in the middle of the dashboard when driving as I focus more on the road. You cannot be distracted when driving at a certain pace. I just ask her how far we need to go on the current stretch of road and how far till the next turn (left of right) or in the case of winding roads, how far on the next hairpin or chicane.
Before the trip, I study ahead of time my itinerary and plan alternate routes if necessary.
