Thanks again @Loz and @Pauly .
I edited the above post but too late.
I found this and changed it to Aus. However in the MFD there was no settings menu. The van had had a steering wheel with buttons fitted (T6 Highline wheel with cruise buttons) in place of its OEM wheel (no buttons - cruise on stalk). I have been into the settings for this and ticked the box for MFSW and saved but the buttons on the wheel still were not active (and the horn was not working either.)
