It controls so that communication may be performed using the object. If the current position is unknown (see the “unknown” route in step B10), the trial order determining unit 2 communicates in the order of the wireless LAN adapter 4b, the wireless modem adapter 4c, and the PDC adapter 4a. The order of connection attempts is determined, and the communication control unit 3 attempts communication connection according to this order (steps B110 to B131).

Then, in these steps B110 to B131, the communication control unit 3 was able to establish a communication connection for the first time among the wireless LAN adapter 4b, the wireless modem adapter 4c, and the PDC adapter 4a. It controls so that communication may be performed using the object. If a communication connection cannot be established by any of the wireless LAN adapter 4b, the wireless modem adapter 4c, and the PDC adapter 4a, it is checked whether or not to try the communication connection again (step (B140) If the user wants to try again (see YES route in step B140), the process returns to step B10.
