Abstract: A navigation device 10 comprises: position detecting means 11 for determining the current position of a user from the absolute position in longitude and latitude by using the electric waves coming from a plurality of artificial satellites going around the earth; storage means 14 for storing the coordinates in longitude and latitude of nodes, as obtained by setting a starting point and a final place, on a scheduled route; display means 12 for displaying the current position and the scheduled route; and control means 16 for controlling the display on the display means 12 by converting the angular data of the absolute positions and the coordinates into distance data while making corrections according to the current position, and by calculating an element between the nodes thereby to calculate whether or not the current position is on the scheduled route, in dependence upon whether or not the distance between the element and the current position is within a predetermined range.

Abstract: A current place indicating icon a for indicating the current place of a user, a used road image b for indicating a used road being followed by the user, an option road image c for indicating an option road connected to the used road and located in front of the current place in the traveling direction, and a way point indicating icon d set by the user and located in front of the current place in the traveling direction are displayed in the screen X of a display unit 7.

Abstract: A navigation system for displaying the information on at least the situations of a user in the screen x of a display unit. The entirety of the screen X can be so switched that a plurality of display modes may be automatically displayed at a suitable timing by the setting of the user. The navigation system has a menu mode for making the aforementioned setting, in which thumbnails T1 to T5 for reducing and displaying the individual designs of the display modes other than the menu mode are displayed in the screen X.
