A communication state monitoring section 35 of a terminal unit 2 installed in a vehicle checks whether communication is possible between the terminal unit 2 and a server system 3. If the section in question finds communication is not possible, information regarding the current position of the vehicle and its target point and search condition acquired by the terminal unit 2 is stored in an internal memory, and communication is suspended. Communication state is checked at predetermined intervals. As soon as it is confirmed that communication is possible, a system control portion 20 instructs a terminal communication section 11 to transmit a signal carrying the necessary data stored in the internal memory to a server system 3. The server system 3 determines a path to be taken by the mobile body based on the data and transmits a signal notifying the path to the terminal unit 2. The terminal unit 2 receives the signal notifying the path thanks to the recovery of communication state and guides the navigation of the vehicle based on information about the path. According to this system, it is not necessary to restart operations even if communication is interrupted and recovers after a certain interval, which will improve the utility of the system.
