My smartphone has updated to 1.1.407 wk 07 and is now updating the maps
Edit1 12 feb
map update was minimal (version 188.8.131.52) but voices were gone and had to reinstall

I looked up and map version number is the same as before. Then what was the update about? It took a long long time to update the maps

Another update to 1.41 followed by a map update that took just a few minutes. Same map build, thus HERE must have done a version check.
And the voices were not gone this time
