I have a 2007 A4 Avant with RNSE MMI, it has the phone system which works with the steering wheel function but on the unit itsself all I get is a note message saying

When you receive a call the following options can be selected using the rotary pushbutton.

I can't get anymore than that, I'm connected via Bluetooth but I don't get the bluetooth symbol appear on the bottom of the screen.

Could this be the software version I'm running ?

Your help would be appreciated.
