ABSTRACT:
When a vehicle is within a predetermined distance from an intersection during the execution of navigation operations, a navigation system displays an enlarged guide map of the same intersection. The guide map shows direction labels that are set for roads that are connected to a road to be approached by the vehicle. The direction labels are set for the connecting roads by tracking the connecting roads and by determining appropriate direction labels following a predetermined procedure. For example, names of tollgates, names of stations, names of special facilities, names of administrative units, names of highways or the like may be set as direction labels.
