Bluetooth Phone Connectivity in LR4

[big foot]

Hello, on my Touareg I can hit the steering wheel "hangup" then "call" buttons in quick succession to initiate the voice dial feature on my iPhone or other phones with their own inbuilt voice dial feature. (Note I am not talking about the vehicle voice dial feature which is cumbersome, inaccurate and involves 3 steps when compared to the phone voice dial capability. It's also not practical for Land Rover to expect customers to teach the car 300+ numbers.) Given that it is illegal in this state to touch an unmounted phone to initiate the voice dial feature on phone, it would be enormously beneficial for drivers to be able to use vehicle switchgear to put the phone into voice dial mode. Anyone any idea on how to do this? Cheers
