Also another misconception is that the instrument cluster is part of the MBUX update, however the instrument cluster is a totally different system (infact the control unit for it sits under the front left seat).
I suspect most of us don't really know exactly what the MBUX includes or excludes. I would have assumed Infotainment inc radio, USB, Internet, ACP/AA, SatNav, Phone, Office, Bluetooth, Voice Commands, Profiles etc and you are right I would have assumed that this included the drivers display as well.
Presumably though within the MBUX there are sub modules such as SatNav, Maps, Infotainment etc that are updated OTA where as the MBUX itself is not sadly although reading this article is seems that MB think it is 🤣
Over the air: updates become upgrades at Mercedes-Benz: Always up to date: Mercedes-Benz vehicles are constantly learning over the air | marsMediaSite This is only a gentle gibe as we know FUP updates can't be done OTA but the table at the bottom of the article says the Mercedes me Store feature is available OTA on cars built pre 06/19 which it can if the MBUX has been updated to FUP1 which it was not ex factory. Probably just Marketing not understanding what Technical have told them 🤣
