I dont understand what this feature stands for. Thé navigator keep making me riding for kilomètres in the countryside beetween two waypoint while my next costumer is a few hundred mètres behind me... Using Tom-Tom map. A simple u-turn here would save me a lot of time.... And gaz! The only way I found is to stop/start navigation to recalculate the itinerary after each costumer wich is annoying with the bike's glove. Help please!!!
