The hand-held unit includes a wide area transceiver for station outside of the vehicle and a short-range radio transceiver the hands-free unit includes a microphone and speaker and is mounted in a fixed location in the vehicle. A short range radio link operatively connects the hand-held unit and the hands-free unit to enable voice and data signals to be exchanged between the hand-held unit and the hands-free unit. The hands-free unit may include a programmable memory unit to store a user table containing user identification data and configuration data. The hands-free unit control logic configures the hands-free unit based on the user identification received from the hand-held unit, thus allowing multiple users to have their preferences recognized by an individual hands-free unit.
