UPDATE: Received and installed MBUX 3.3 update today. I removed the car from my mercedes me profile and reset it completely. About an hour after setting up my profile (the next day) I got a notification an OTA update is available. I am unsure if my method forced an update check or if it was released for other drivers in the US.
My 2025 C300 hasn't updated since MBUX3.2.2 installed 06/27/2025. While the Mercedes Me app says no updates available, I cannot find where to get my display to show what version I'm on. I thought it would be either in System or Info in Settings, but I don't see it.

I tried the trick of deleting the app and reinstalling it. Nothing. I wonder if the updates are linked to the model year. Two folks here with 2025's are at 3, while my 2024 is at 2.
I took a deep dive in Google. 700,000 cars worldwide are getting the 3.3 update. This seems to be tied to 3rd gen MBUX. That means you have NTG7 software (found in Info), but apparently not all NTG7 software is 3rd gen. I think it applies to 2025 models, and mine is a 2024. So I do have NTG7, but I believe I am 2nd generation. I'm not sure why you folks with 2025's aren't getting it, maybe the rollout hasn't hit your area yet.
For reference, my software is RL_NTG7_E505.404_24441AC3.
I hope that clears some of this up.

You are correct the 2025 c300 introduced generation 3 of MBUX (NTG7) while 2024 and lower are on 2nd gen. Therefore, your software updates will only always be 2.x.x. This is just a different set up of updates from 3.x.x. My 2023 c300 is on 2.6.1 which is currently the newest version and actually introduced the changes like sound drive & atmos included in 3.3 way earlier.
It's very disappointing that MB changes a few app icon designs and calls it 3rd generation, withholding it from previous model year w206s. Wish they all got major generation updates. I wonder if newer/faster chips in the 2025 are the bottleneck. I doubt it though since both generations are nearly identical. The 2025 is noticeably faster though.
My 2024 C300 shows no update available. My last update was a 2 point something last June. Maybe this is how Mercedes convinces people to buy newer cars. Although I have a three year lease and it’s not happening for me till the lease is up.
Yep, no update for you. Second-gen MBUX in the '24s. However, a lot of what is listed in the 3x update is what we got in the latest 2x update, so no big loss.
