Different drivers are provided with different car keys 133. When receiving the identifier 134 first time, the HFU stores trusted data to pair with a driver's phone. Thereafter, the HFU automatically connects to the driver's phone when the same car key 133 is used. The hands-free unit typically comprises a microphone and a loudspeaker, and can also have a display and/or a camera. In operation the HFU provides automatic link 160 with a compliant LPRF enabled mobile phone without need to touch the mobile phone, allowing its use even when the mobile phone is placed in a boot of a car 101.",
