Yes, I updated a few weeks ago. My phone and a Garmin satnav both accept the postcode, so it looks as if the VW satnav is behind the times.
No, I cannot find any such button. This is baffling. I have emailed VW for an explanation.
Sorry to dig up the thread.
Have you got this to work now? Same case for me, my "home address" in Preston Lancs. is actually a new build and won't recognise a post code.
Is there an update I can do from within the car or, shall I wait for it to update itself?
Thanks.
