Abstract: A route guidance system comprises first and second route search severs, which are provided with first and second areas as service providing areas, and terminals. When the terminals request route search, the first route search server determines the second route search sever, determines whether or not the terminals can perform roaming in the second area, transmits to the second route search sever point information and information as to whether or not the roaming is possible, and requests the route search. The second route search server searches for an optimal route which satisfies a route search condition. If the roaming is determined to be impossible, the second route search server determines a data format in which data can be outputted, creates guidance route information by editing the information on optimal route into the data format, and transmits the guidance route information to the terminals (20) through the first route search server.

Abstract: When a map display system acquires first map data on an area of a predetermined range with a first display scale, the map display system also acquires second map data on an area of a larger range including the predetermined range with a second display scale at the same time. When the acquired first map data on the area of the predetermined range becomes insufficient since a first map displayed on a display means is scrolled, a map obtained by changing the display scale of the second map data to the first display scale is displayed. This provides the map display system which is controlled so as to efficiently acquire map data suitable for a communication type navigation system.
