Don't forget to pray. Updating the MMI firmware is not without risks. And you better make sure your battery doesn't die mid way through the update.
I have a 2018 B9 with Qualcomm processor and the 1320 MMI version. Will I get the new Maxar satellite overlay if I update to the 1316 or the newest MMI version for the Qualcomm head units?
Have you had any luck in getting the update to work? I went through the meta file and only saw K/P variants in SupportedTrains. Since we're on a much older version we might need to do all the updates leading up to 1439 before flashing 1439. But that's just my speculation. It would be nice to update to see if my carplay/bluetooth issues go away.
I just successfully directly upgraded from 0377 to 4139. I took the risk of using a custom metainfo file that ignored the train mismatch of my unit and also ripped out some of the Bose stuff (well I didn't modify it but a very helpful Telegram group helped). Everything seems to work!
EDIT: I would like to note that it took me 9 months to get to this point (haha yeah very funny). Eventually I bit the bullet and took a big risk with nice rewards. Before: MMI2_US_AUG22_S2139 / MU 0377 After: MMI2_US_AUG22_K3345 / MU 1439

Reason: Additional commentary
Congrats! How do you see this version? All I see is below - My car is 2017 A4 Premium. How do I know what software I am at? Thanks in advance!

Nice! Have you notices any changes with the new firmware? Any new problems/bugs?
I'm still rocking the really old firmware, I've had weird issues with carplay crashing but I haven't had that in a while, and sometimes the backup camera doesn't show up.
I'll risk the upgrade if it doesn't bring any new issues.

Did some more digging and found a firmware version 1422 with support for MHI2_US_AUG22_S2139 trains. Going to attempt upgrade to this version when I get back from a roadtrip.
I'm not sure what the rules are regarding sharing links from other sites, but the filename for this 1422 firmware is
This update addresses multiple customer concerns and optimizes general system performance. This update
should be run for the customer concerns below before any other repairs are attempted.
Examples for possible customer concerns that are fixed with this software:
MMI no audio issues.
Infotainment system reboots while driving.
myAudi PIN is not accepted.
Google Earth maps inoperable.
Subwoofer settings not available.
Ringtone inoperable.
Settings change by themselves.
myAudi navigation destinations are not received.

Hopefully this update also allows me to update my maps to a more recent version and fixes some weird bugs/issues I have.
