receive the movement guidance information transmitted from the server device in response to the request for the movement guidance information;
provide movement guidance for the mobile unit using the received movement guidance information;
after receiving the movement guidance information, transmit a route search request for a destination to the server device, wherein the movement guidance information is received before setting the destination and before providing the movement guidance; and
after providing the movement guidance of the mobile unit, receive a route searched for and delivered by the server device in response to the transmitted request; and

the server device includes a second processor programmed to:
receive the request for the movement guidance information from the communication terminal;
transmit the movement guidance information for a target area to the communication terminal in response to the request for the movement guidance information;
