Help with rerouting MIC for columbus

My dealer has inadvertently enabled the voice control function on my columbus which is running fw 2724 .

I now would like to reroute the mic as described here: http://www.my-gti.com/1234

It says to take the mic from the bluetooth connector to the columbus and back to the bluetooth connector.

Can anyone tell me where the bluetooth connector is on a 59 plate superb?

Also, has anyone done this and is it easy? How does one remove the columbus to get at the back.

Any pics will be very much appreciated!

Thanks
