Is it possible to speak privately on my Nokia Display Car Kit CK-600?
To switch from handsfree use to mobile phone use without interrupting the ongoing call ,on your Nokia Display Car Kit CK-600, terminate the Bluetooth connection by pressing and holding the mute key during the call and use your mobile phone, or thereafter transfer the call to a headset. Pressing and holding the mute key will re-connect the car kit with the mobile phone and transfer the call to the car kit.
