@ Alexis_
You can split 2016.10 with Gmaptool by subfiles and replace CN_RUSSI.SID with CNRUSSIA.SID posted above, then Join, no need to redownload again the whole map. That file only has been replaced in 2016.11.
No changes in gmap too.
But this 2016.11 is optional for newer devices only
Spoiler: Google translation and source


version 2016.11 is installed as an update to a few thousand official buyers
-Garmin has released this update in conjunction with the release of new devices,these customers need to install this update
