My navi shut down when I turned it off by accident - was in a jam at the time and had shut the engine down. To get it back up and running I had to enter my 4 digit PIN. I duly did so, but it didn't like it and after a few attempts shut down. That's annoying enough in itself. Worse though, I can now not even try entering that PIN again (not that it would do any good it seems) without first entering an 8 digit PUK PIN. Now I've no idea what this is and have checked all docs and found nothing that could be it. Anyone else had a similar experience? Asking here first in the hope that I can avoid a weekend trip to the dealer which will take up half a day.
