Abstract
A navigation system includes a display control for controlling a display monitor on which a road map and a trace of the vehicle position are to be displayed. The navigation system also includes means for detecting when the vehicle reaches a known point on a preset route. The display control is responsive to detection of the vehicle reaching the known point to erase the displayed trace and set the vehicle position to that of the corresponding known point on the displayed map.
