<p>A navigation system utilizes a digitized road network stored in a non-volatile memory and determines therefrom a travel route from a starting point to a destination point. A partial route is calculated from the starting point to an intermediate destination point and maneuvers for this partial route are generated and output to the user in order to guide the user even before the complete route to the destination point has been fully calculated. When a complete route from the starting point to the destination point has been calculated, the calculated complete route is overlapped with the partial route to define an intersection point between the two routes. The proposed maneuvers for that complete route are then output beginning from the intersection point.</p> |
