A server is connected to a communication terminal and configured to receive a departure point, a destination, and a route retrieval request from the departure point to the destination from the terminal and to deliver a route retrieved in response to the received route retrieval request to the terminal. When the route retrieval request is acquired from the terminal, the server acquires route information related to a target route that is a route corresponding to a predetermined distance from the departure point in a terminal-recommended route that is a route from the departure point to the destination and is retrieved by using terminal-side map information provided in the terminal. The server retrieves a route to the destination that includes at least a part of the target route by using device-side map information provided in the server and the route information, and delivers the retrieved route to the terminal.
