I am witting a car navigation application using MapPoints GPS. I am able to use MapPoints built in GPS functionality but not their turn-by-turn instructions. Using Paul Larson's API as an example i use windows messages to enable the GPS and driving guidance but the guidance always says "Proceed to Route". Has anyone been able to receive the built in turn by turn instructions from mapPoint? Also, i have noticed that when i open MapPoint via code, the "GPS Pane" button in the RoutePlanner pane disappears. But it is there when i open MapPoint normally and the turn by turn works. Could this be connected?
Also does any one know how accurate the GetLocation(..) is when the altitude 1 (at its lowest)? I am assuming it has to be greater than .5 miles.
Any advice would help
