The system update app is the app with the blue OTA icon and the white cloud with the "up arrow"..
Note also that OTA updates are done sqeuentially.
It means that if you are a few updates behind, you have to:
- check for updates
- download update
- install update
And that maybe 2-4 times in a row.
I also had to do that last week or so when I hadn't used my car for over a week.
