First of all, thanks everyone for all the info is this topic; it helped me a lot! I succesfully updated my infotainment system from 1790 to 1899 to 1969. I had a few hesitations before updating:
- First off all, i wasn't sure my infotainment system was correct for the update. The last letter of my device number (in my case, a D) was not found in anyone else's photo's. Everyone had a different letter at the end. I now know, this last letter is not relevant for the check. As long as your device number starts with 5FA035862, you should be fine, in my opinion. After updating from 1790 to 1899, I even discovered that the last letter of my devicenumber had changed (now a M)! See pictures below.
- My car originally didn't had Carplay/ Android auto. My dealer activated this for me. I was a little bit afraid, that after the update, this may be broken. But is was not the case.

So how did the update process go? I had some little complications.
When i first started the update from 1790 to 1899; i only saw a black screen (with a back button) for 4 minutes. After a while, it continued, and one update was installed fairly quickly (within 30 seconds). The system then restarted. I was still on version 1790 at that point.

When I performed the update to 1899 again, the black screen with only the back button appeared again. After 4 mintutes the update to 1899 started and was succesfully installed.

After the update of 1899, i did the same procedure for 1969; this went quick and smooth.
