    摘要： A navigation system (2) includes a map-gain timing judging part(15) to calculate a traveling speed from the position of a vehicle detected by a GPS unit (13). A moving distance of the vehicle during the renewal of map is calculated by the traveling speed and a renewal time necessary for gaining the map information from the server (11) of a map information delivery apparatus (1). The system(2)further calculates a traveling direction of the vehicle by the position of the vehicle and also calculates a road distance from the present position of the vehicle to the margin of a map on display. When the road distance agrees with moving distance, it is started to gain new map information from the server. Thus, when the vehicle reaches the margin of the map on display, the renewal of the map information is completed.
