PROBLEM TO BE SOLVED: To solve the problem that a user feels inconvenience or a storage capacity is excessively used when a guidance route passes a communication disabled area.SOLUTION: A smart phone 20 transmits information for route search and map data information whose distribution is not required to a server 50 (step S112). When receiving the information for route search, the server 50 executes route search by using the information for route search (step S125). When the distribution of the map data of a region including a destination is required (step S130), the server 50 distributes the map data as second map data to a smart phone 20, and distributes the route information to be guided by using the distributed map data among the searched route information (step S135). The second map data are obtained as map data scheduled to be used for the route guidance, and as map data to be distributed before the self-position of the smart phone 20 is positioned in a communication disabled area. |
