Text information of display objects matched to the objects is read out from the map data and is displayed on the locations of the objects displayed on the screen. If a user moves, a travel route is guided using the matching information between the objects and display objects, so the user can be guided with the travel route while personally checking objects such as a building.;EFFECT: accomplishment of enhanced precision navigation tasks.;32 cl, 8 dwg
