Excellent !
So yes, it has the latest 3.1.1 firmware and SN is not activated, so you're getting the "real" GPS position, so with very poor reception conditions in dense urban areas, you may see some "wobbling", if it bothers you, just hit "StatNav ON" and you will see a 01.

Hope that helps others who is as curious as I am.
Cheers.
