If a destination set on a display 3 is a facility not having connection relation between facilities stored in a facility information DB 84, a scroll direction detecting unit 92 that detects a scroll direction of a map 31 detects a direction instructed for scroll as the scroll direction and a display controlling unit 94 performs scroll of the map 31 in the scroll direction. In addition, if the set destination is a facility having the connection relation between the facilities, the scroll direction detecting unit 92 that detects a scroll direction of the map 31 detects the scroll direction based on the connection relation of the destination and the direction instructed for scroll and the display controlling unit 94 performs the scroll of the map 31 to a position of a facility connected to the destination in the scroll direction.
