correct, it's turned off on the cars that don't have the full voice control option.

allows you to have bluetooth phone dialing by voice, even if your car didn't come with the speech package. Many A6's aren't equipped with that package, so without this hack, pressing the speech button on the steering wheel just flashes a frustrating message - "button inactive"

Thanks Bob - Good resource!

Firstly, this is a brilliant option - thanks for telling us about it.

In order for it to work on my Irish A6, I had to

change the coding from 0010900 to 0010920.

Thanks again
