My smart phone does better then the on-board GPS unit in truck. It even has a GPS app. Just enter the coordinates and off you go. If you find a place you'd like to return to just use the app in your smart phone to get the coordinates. The GPS mapping unit these manufactures install in cars are a joke.
My joke of an in-car system worked great while I was traveling Canada and remote Alaska. No cell service, a smartphone is useless. Even with a downloaded map, my smartphone could not get a GPS lock, because it relies on the cellular network to calibrate the gps receiver for the initial fix.
In urban areas, I've had Google Maps try to get me to take some pretty strange routes, like through a residential subdivision, down a 2 track power line easement and through a locked gate at the end of a dirt road.
