How frequently does http://garmin.openstreetmap.nl/ update maps from openstreetmap? Below the map image it says Slippy map and Garmin maps are based on OpenStreetMap data. Map version: 07-11-2015, is the map I downloaded really from 7-11-15?
“weekly/varies” according to this comparison chart.
I see it now says “Map version: 22-11-2015” …so yeah. That must be the date it was updated from OpenStreetMap.
Keep in mind that the date is displayed according to the Dutch formatting, so days before months ! 7-11-2015 is November 7.
This is clear from Harry’s post where 22-11-2015 wouldn’t be a valid date according to US-formatting. It means November 22, 2015
