How do I make and receive calls with the Nokia Bluetooth Display Car Kit CK-15W?

You can make phone calls from a contact list that has been downloaded from your mobile phone to the car kit, if supported by the connected mobile phone. You do not need to remember numbers or use your mobile with your hands while driving. You can also accept and reject calls, redial, use voice dial, mute the microphone, and control the audio volume with the input device.
