What will be an ideal response?


Amanda first turns on her Bluetooth-enabled cell phone to pair it with the Bluetooth device in the car. She then can control the phone with buttons on her steering wheel. Amanda presses the Talk button on the steering wheel and says aloud the name of the person she's calling. Her cell phone dials the number that is stored in the car's phone book. The dialing and caller information as well as signal and battery strength appear on her car's instrument panel. Once the person answers the call, Amanda can talk hands-free. The Bluetooth system also works with the car's navigation system, so Amanda can auto-dial phone numbers associated with local points of interest, such as hotels and restaurants.
