8. A guide route distribution method comprising the steps of:
-
at a predetermined reception unit, receiving information indicating a start point, information indicating a destination, map data generation information for identifying generation of map data possessed by an mobile terminal, and route search program generation information for identifying generation of a route search program for performing route search of a guide route from the start point to the destination, which is possessed by the mobile terminal, from the mobile terminal; at a predetermined first route search unit, searching for a first route which is a guide route from the start point to the destination, based on map data of a generation indicated by the map data generation information and a route search program of a generation indicated by the route search program generation information, which are read by a predetermined storage unit; at a predetermined second route search unit, searching for a second route which is a guide route from the start point to the destination, based on map data of a generation equal to or updated from the map data possessed by the mobile terminal and a route search program of a generation equal to or updated from the route search program possessed by the mobile terminal, which are read by the storage unit; at a predetermined comparison determination unit, comparing the first route and the second route and determining whether a predetermined guide route update condition is satisfied; and at a predetermined transmission unit, transmitting the second route to the mobile terminal only when the guide route update condition is satisfied.
