A method for obtaining additional information pertaining to a route along which a vehicle is traveling from a current location to a destination. Location information of the vehicle, which includes the current location, is acquired by an in-vehicle computer within the vehicle. The in-vehicle computer transmits to a server via a network: the location information, movable range information, and selection criteria information. A movable range derivable from the movable range information is an area relative to the current location in which the vehicle can travel from the current location by using a remaining amount of fuel in the vehicle when the vehicle is at the current location. A limited range with respect to the route is a function of the location information, the movable range information, and the selection criteria information. The in-vehicle computer receives, from the server, additional information limited to information concerning locations within the limited range.
