An on-vehicle navigation device (1) with a hands-free function establishes a Bluetooth communication line to a mobile telephone (10) and receives call history data and arrival history data stored by the mobile telephone (10) before establishment of the Bluetooth communication line, from the mobile telephone (10). The on-vehicle navigation device (1) stores the call history data and the arrival history data in a work memory (6) in the equivalent condition as the call history data and the arrival history data in the local device. After this, it is possible to perform a call operation by the call history data and the arrival history data stored in the work memory (6).
