Abstract
At least one of outbound call history data, inbound call history data, and phone book data is transferred to a handsfree apparatus for use in a vehicle at a predetermined timing for the purpose of obtaining near realtime update of the inbound/outbound call history data from a cellular phone. By utilizing simultaneous connection of HFP and PBAP, the handsfree apparatus establishes a Bluetooth communication with the cellular phone through HFP first, and then establishes another communication through PBAP simultaneously, for receiving the inbound call history data and the outbound call history data stored before establishing the Bluetooth communication from the cellular phone. The handsfree apparatus can thus be capable of placing a call by using the outbound call history data and the inbound call history data stored in a work memory after receiving those data.
