I picked up my new GTI last week which has factory fitted RNS510

and as a result also has the Highline trip computer.
But for the life of me I can't get into the menus to change settings etc!!! The manual says something along the lines of, "turn on the ignition, a pictogram of a car is displayed and then press the button on the underside of the stalk once".
But no joy

When I turn on the ignition it says "Volkswagen something something" for a couple of seconds and then switches straight to the normal display. The only way I can get the pictogram to display is to open the door! What am I doing wrong?!!
