@congo This whole GEMMI reprovision tactic seems to be floating around in variety of iterations here and elsewhere for about the same cost. Looking over your statements in this thread you're tying your changes to the MMI through BTMAC/VIN to identify users in your system that is tying into the original GE API through Audi backend somehow through a proxy via a valid "license" i.e. working VIN MY 2018+ to trigger the updates to flow.

When GE disabled their API 12/2015 it seems as if VAG ported a copy over to their own server and supplied the data on their own metal w/ a replication from GE to support the defunct API configured in older MMI units. So, either this method is updating the 10th character in the VIN to something post 2018 and tracking users on your side by BTMAC as the identifier or the proxy method / license bypass.

As an insight providers like TM / ATT / etc. have devices called "Google Cache" that store searches for faster response w/o sending an external lookup to GG each time thus cutting the bandwidth needed and lower latency to EU devices in the process. They're very effective in cutting down the need for WAN bandwidth after they scrape GG information for download to the cache itself. I'm guessing that something similar is in play for the GE "product" that VAG disabled for older models and left in place for current systems.

The whole excuse that the HW in older models doesn't support an overlay image tied to a spontaneous download from the API is stupid as it's been working for at least the last 5 years w/o issue and it's also damaging the VAG brands by saying they can't support their own products. It's either a waiting game for them to turn it back on w/ the backlash they've produced or lose a customer base that had been loyal to the technical abilities no one else had shown in the past. In the past VAG has been a forerunner in tech in vehicles and now the innovation seems to have subsided.

Not sure about this as it's not something I needed to do other than put a different sim in the unit and apply the appropriate APN in the connection screen to make it work.

As to the MMI 3G+ not being supported that's fine but the reasoning behind disabling it just doesn't jive with the HW being incompatible reason that was given. Sure it's a bit antiquated in comparison with what's on the market these days but, it's still more powerful than the systems that supported the Apollo missions in the 60's.

Anyway... I shot you a PM the other day on another matter regarding UMTS activation....

As to the whole buy from yourself enterprise issue... yes, same here in the states as some TV stations were having the same issue with broadcasting rights / fees in dispute with other carriers outside of themselves under the corporate umbrella. What doesn't make much sense though is if you install the new FW on the MMI and the Maps get updated (30GB) why can't the system just run the overlay based on the HD images preloaded instead of that 90's look that shows up?
