If you have a car fitted with the Multi Function Steering Wheel it is possible to modify the coding so that you can use the Mute button on the steering wheel to activate the voice dialling function of the installed telephone system.
Using VAG-COM open Controller 16 - Steering and select Coding 07.
You should see a 7 digit softcode which will be in the format 00xxxxx
The 4th digit from the right corresponds to the steering wheel variant. If you have a 4 spoke MFSW without the Cruise Control buttons it should be a 2. Change this to a 3 and that should convert your Mute button to activate the Voice Dialling.
Setup
Follow the guidelines for your telephone to add a Bluetooth device, the pass code is 1234 - You may note that this can be changed by adapting channel 135.
When you turn on the ignition the Bluetooth System will locate your telephone, momentarily mute the radio and give an audible confirmation tone. Conversely when disconnecting you will also hear a confirmation tone.
