A system and method for automatically configuring a communications system between a local mode in which a local communications device (such as an in-vehicle device or “land-line phone”) is active and a remote mode in which a mobile communications device is active and coupled to the communications system. One example of the method includes searching for a Bluetooth™ enabled device, selecting the remote mode of operation responsive to detection of the Bluetooth™ enabled device, and selecting the local mode of operation responsive to failure to detect the Bluetooth™ enabled device. In one example, selecting the local mode of operation includes activating the local communications device, and selecting the remote mode of operation includes activating local Bluetooth™ systems to connect the Bluetooth™ enabled device to the communications system.
