Abstract: Operating parameters of a hands-free audio system used with a wireless communication device in a moving vehicle are adjusted or tuned in real-time and requires only two persons: one to drive the vehicle and thus provide actual usage conditions with the hands-free audio system and one to remotely tune or adjust operating parameters to optimize far end audio quality. The system is remotely tuned by transmitting audio signals from the vehicle to the far end using a first communications link to the far end and sending adjustment commands to the vehicle from the far end via a second, data link between the far end and the vehicle. In one embodiment, DTMF signals received from inside or outside the vehicle can tune or be used to diagnose the hands-free system. Test measurements obtained from within and by the hands-free audio system can also be retrieved from a remote location.
