We haven’t used it. Last year we started to us it to plan a trip from NM to Vinnie’s. When we noticed that the mileage seemed kind of high for several legs of the trip we inspected the recommended trek closer. It had two “loops” in it that added over 200 miles. Have no idea what it was doing so we never looked at it again.
Currently, the wife makes plans using google maps or Apple Maps then we put the days destination in the trucks GPS (Pioneer NEC) and use waypoints or rout avoidance to make it match her planned route. Takes about 5 min to enter the route first thing every driving day.
