By siting by the siting method, the distribution sites of the distribution centers are as compact as possible, and the distribution centers are as separate as possible. Finally, distribution cost is locally optimized.

Upon receiving a request from a vehicle-mounted device 100, a distribution center 200 executes a recommend route calculation and a guide calculation and transmits recommended route information and the data size of guide information to the vehicle-mounted device 100. The vehicle-mounted device 100 calculates the estimated download time based upon the size of the guide information and displays it. If the driver requests a split download, the vehicle-mounted device 100 outputs a split-download instruction to the distribution center 200. The distribution center 200 transmits to the vehicle-mounted device 100 guide information to be used to guide the vehicle from the start point to the first guidance-requiring intersection. While executing the route guide processing, the vehicle-mounted device 100 downloads the remaining guide information in the background.
