Recalculate a route from your current location
If you are using a Global Positioning System (GPS) receiver with MapPoint, you can recalculate your route from your GPS-supplied location to get back on a route that you have left or to re-create your route after a detour. For your current location to be available to MapPoint, your GPS receiver must be receiving a satellite signal. Tall buildings, overpasses, and tunnels, among other things, can block your GPS receiver.
To recalculate a route from your current location
-
Open the GPS pane and make sure that the GPS receiver is getting a signal.
-
Under Routing, in the Recalculate route from current location to box, type or select the place or address to which you want to go.
-
Click Go (F3) or press F3.
Note MapPoint refreshes the map to include your current location as a numbered waypoint and to show the new route. If the Directions pane is open, the turn-by-turn directions also reflect the changes.
