PURPOSE: An apparatus for automatically setting a vehicle clock using a Bluetooth handsfree system is provided to set exact time without the necessity of an additional circuit by receiving time data from a mobile phone and automatically setting the time of a vehicle clock. CONSTITUTION: A mobile phone(10) receives time data from a base station and displays the correct time. A Bluetooth module(12), embedded in the mobile phone(10), transmits the time data, received from the base station, to a handsfree unit(20). A Bluetooth module(22), embedded in the handsfree unit(20), receives the time data from the Bluetooth module(12) of the mobile phone(10) and outputs the time data to a DSP(Digital Signal Processor)(24). The DSP(24), receiving the time data outputted from the Bluetooth module(22), transmits the time data and a time resetting signal to a vehicle clock(30) so that the time of the vehicle clock(30) can be reset.
