ABSTRACT:
A map display device includes a display for displaying map data, a position detector for detecting a position of a subject vehicle, a map data storage for storing the map data and a controller for processing the map data. The controller determines whether the subject vehicle is traveling outside of a road on a map displayed on the display based on the current position of the subject vehicle. The controller updates the map data upon receiving an affirmative response for confirmation of an update of a portion of the map data including a path of the current position of the subject vehicle on the map.
