You have to convert that to hexadecimal, your UIN is 2D075039002850643675:

Re: PSA NAC RCC Updates
Hi Rui,
I have some good news.
I prepared a new USB flash drive using Peugeot Update on a Windows PC instead of macOS, and the map update completed successfully. Everything is now working perfectly.
So the issue was indeed related to preparing the USB on macOS, even though I had already removed the hidden files and verified that there were no extra files in the MAP folder.
Thank you very much for your help and for pointing me in the right direction. I really appreciate the time you took to help me solve this problem.
Thanks again for everything you do for the PSA/Stellantis community!

New member says hi!
I have a DS7 Crossback E-tense 2019. A few days ago MyDS app told me there is a new software available to my car, version: 42.03.33.42_NAC-r0.
Current version in my car is: 44.07.33.32_NAC-r0 (from 2023-08-21). I thought WTF...
Well, I did download the version MyDS announced to the USB stick, but it didn't even recognized in the car.
I read this topic and special thanks to Rui Saraiva, here is a lot of information.
My car´s VIN-code tells: From factory, my car had a NAC_EUR_WAVE3 infotainment system.
But in reality my car currently has a NAC_EUR_WAVE4 system. So, the information stored in the Stellantis servers was not updated.
For some reason today MyDS had updated itself, and did not notify of new updates, and the version reported by the app had updated to the version what is in the car. Maybe it was updated yesterday via Google Android Auto, I don't know.
So something has been done on the Stellantis servers...
