Abstract

A vehicle navigation device is provided for permitting the display of the current POI (Point of Interest) information about points of interest which serve as landmarks near a guidance route to the destination, thereby improving visibility when a user identifies the guidance route. A vehicle navigation device 50 is connected in communication with a provider 60 for offering transmission service of map information which includes the current POI information pertaining to locations on a map where the points of interest are located. The navigation device 50 includes a display unit 6, information input means 2, communications means 3, and control means 17. The control means 17 accesses the provider 60 through the communications means 3 when the guidance route to the destination is set by the information input means 2, to obtain the current POI information about an area near the set guidance route from the map information, so that the obtained current POI information is displayed on a screen of the display unit 6, together with the guidance route and a vehicle position mark for designating a present position of a vehicle.
