The same navigation information and facility information are directly distributed to both a vehicle-mounted navigation device and a portable terminal. A server is connected to the vehicle-mounted navigation device and portable terminal in a manner able to communicate, wherein on the basis of an information distribution request from the vehicle-mounted navigation device, facility information satisfying a predetermined standard is searched from a storage unit and distributed to the vehicle-mounted navigation device, it is determined whether or not the portable terminal is present within the vehicle on the basis of the current position information of the vehicle received from the vehicle-mounted navigation device and the current position information of the portable terminal received from the portable terminal, and when it has been determined that the portable terminal is present within the vehicle, the searched-for facility information satisfying the predetermined standard is directly distributed to the portable terminal as well.
