Or edge it on if you get impatient as I explain. Jury is a bit out at the minute on when completion occurs. Those with LEDs on their USBs see activity still going on after the map appears to update by the YY.MM on the screen which means the job isnt done when that first appears. Given the connect services structure of the map is designed to update in parts as you travel requesting an update or your strike a route on the destination to force the connect services update, you may just be getting the update for your zone, like South of England say. Wait a bit longer and you get the whole lot.
The Briskoda people, least some of them take the view you should just leave it in and some take out connect service contract since they don't want to leave it in. That is likely to be an extreme. I suspect you just leave it in for a bit longer where the USB LED people have the upper hand since they can see when its done. Its on the SeatCupra site where LED USBs are liked for this or Briskoda.
I'm just reporting what I've read by you good people. Post 1 on here has the PDFs of the brands and the ambiguity of how long you leave it in. Blissfully I have mib2 high and mib2 standard. I'd buy a LED based USB if I had mib3 was doing this. You format to exFat for speed.
