My Edge has suddenly stopped displaying the map. I think it’s showing the base map (major roads) but since I don’t cycle on those I can’t be sure when I’m riding. When I’m not riding I can see the minor road where we live is not showing, but the nearby A34 is showing. All maps seem to be enabled. I did a factory reset but not helped. Here’s a picture of the maps selected. I’m in UK. Any ideas? 
Hi,
I had the same issue of my maps lacking anything but A roads after updating my Edge 530 with Garmin Express this week. I tried updating my version of Garmin Express to the current one (version 7) and reinstalling the maps, nether of which fixed the issue.
After I read through this thread https://forums.garmin.com/sports-fitness/cycling/f/edge-explore/168178/missing-european-maps I guessed that perhaps residual files on my Edge 530 might mean that after Garmin fixed their Express software and broke up the Europe maps differently perhaps one of the map install images on my device was the problem. So I backed up the following files from my Garmin Edge 530 then deleted them from the 'Garmin' top level directory:
I then unplugged and replugged in my Edge 530 and reinstalled the Garmin Europe Maps using Express, and this worked. After doing this i found the relevant files on my Garmin had changed to the following:
Perhaps one if the map install files was not copying across directly due to the presence of an older one... who knows, good luck!
