W206 Software Version
My guess is, that only minor updates are done OTA - bug fixes and such, and larger updates has to be done by the dealer.
According to the dealer, a complete MBUX update takes about 4 hours - I wouldn't trust an update of that size to be done OTA

This is my software, before the update (and I'm in Denmark - the car rolled of the production line in Germany 5. month of 2021)

I'm in Denmark, and after the update of MBUX yesterday (the car is still at the dealership), my Mercedes Me app informed that there were new digital services available, and suddenly I am able to purchase Dashcam!

For versions it was a big step from E023 to E329 !!
The version is now E330.602_23063AC3.
Previous version in my car was E316.505_22092AC3.
The entire system seems to have become quite a bit more responsive at least during startup than before.
Layout of the permanent part including the A/C controls have changed and the icons have changed as well.
My MBUX software was updated because Apple Carplay was very slow to initiate and resulted in black screen for a while until it was ready.
So this should be the most recent one (US market)
