Hello, I hope I am not mistaken to post here, but I own an old VW up with a Navigon 70/71 Premium Car navigation computer and wondered whether I could update the maps (and even the software). During booting it displays the following information:

BT: H14421-V30R0
BL: 1.58
OS: 2.15
OPENGL: 375

The maps are from 2011 and I have read that there are at least maps from 2020, but I could not find anything to download. I don't know whether this is important or not, but the device is in German.

Kind regards!
