Why don I get a map of my route with OnStar eNav like I see on MaqQuest.com?
OnStar eNav uses your vehicle’s current location as the origin of the trip. When you retrieve the directions in your vehicle, OnStar automatically calculates the best route from that location. You can enter an origin at MapQuest.com, but the map shown online may differ from the directions delivered to your vehicle, depending on your vehicle’s location.
