PROBLEM TO BE SOLVED: To simplify an authentication registration operation to connect an identical radio communication device through a plurality of radio communication channels.SOLUTION: Each of a navigation device 100 and a mobile terminal device 200 executes each authentication registration application 124, 224, to perform authentication registration of both a Wi-Fi channel and a BT channel to an identical opposite device. At this time, each authentication registration application 124, 224 first performs the authentication registration of the Wi-Fi channel with a simple operation by WPS, and thereafter, performs information exchange necessary for authentication registration through the BT channel and synchronization processing through the Wi-Fi channel. Thus, the authentication registration of the BT channel can be performed automatically without any operation by a user. |
