An in-vehicle navigation apparatus with a handsfree function establishes a Bluetooth communication link with a cellular phone. When receiving from the cellular phone outgoing call history data and incoming call history data, which were stored in the cellular phone before establishing the Bluetooth communication link, the in-vehicle navigation apparatus stores, in a work memory, the received outgoing call history data and the received incoming call history data, equally to, of the navigation apparatus itself, outgoing call history data and incoming call history data. An outgoing call operation then becomes possible using outgoing call history data and incoming call history data, which are stored in the work memory. |

1. An in-vehicle handsfree apparatus allowing a handsfree phone call by establishing a wireless connection with a cellular phone, the cellular phone storing incoming call history data indicating a source telephone number of an incoming call, outgoing call history data indicating a destination telephone number of an outgoing call, and phone book data in which a telephone number and a registration name corresponding to the telephone number are registered,
the handsfree apparatus comprising: a control section configured to perform, when the cellular phone exists in a wireless connection area, communication using a transfer protocol for realizing transfer of the incoming call history data, the outgoing call history data, and the phone book data, wherein the incoming call history data, the outgoing call history data, and the phone book data were stored in the cellular phone prior to the wireless connection established between the handsfree apparatus and the cellular phone; a communication section configured to receive the incoming call history data, the outgoing call history data, and the phone book data from the cellular phone via the communication using the transfer protocol; and a data storage section that stores the outgoing call history data, the incoming call history data, and the phone book data, which are received; wherein the outgoing call history data and the incoming call history data are transmitted earlier than the phone book data from the cellular phone via the communication using the transfer protocol, wherein the control section is further configured to
transmit a data transfer demand for the cellular phone to start a transfer process of the outgoing call history data and the incoming call history data, causing the transfer process of the outgoing call history data and the incoming call history data to be performed, to permit the communication section to receive the outgoing call history data and the incoming call history data, andtransmit, after the outgoing call history data and the incoming call history data are received from the cellular phone, a data transfer demand for the cellular phone to perform a transfer process of the phone book data, to permit the communication section to receive the phone book data. |
