Same now happened to me twice on a brand new Edge Explore. Updated software and maps and then no map - nor will it download routes I have made on the web corse creator. Returned it as faulty, got a new one, updated again and ended up with another brick.
Are you talking about Garmin Maps? If so, try to reload via Garmin Express... might help.
I have the same problem I reported to Garmin they replace the unit and it was fine but after installing my phones sd card etc etc I swich on the device and the maps disappear again :/ does anyone know how to fix this?
FWIW, I have a new (as of 5/9/20) 1030 (Bontrager version) and was on a ride yesterday and I scrolled to the MAP: screen. I started seeing my path and bodies of water, but nothing else (at least I saw lines and ponds - no roads). There was a short period when I THINK that messing with that hand icon would bring a map up. More messing and it would go away. Then the map was gone no matter what I did so I rode for another 5 minutes doing nothing.
I pulled off the side of the road to see if I could figure it out. I looked down and I had maps again and have not seen them disappear since then. I have not updated the software (I am running "Software Version 7.5 per 'ABOUT' on my device.

What you see is the basemap, which is always ON but not useful for navigation, just to locate yourself when you zoom way out. Go to an activity profile, then Navigation, Map, and when you see the list of loaded map, one should be called something like "... Garmin Cycling Map ..." exact name depend on the region you live in. Make sure it ENABLED. If it is not enabled, enable it. If it is not there, you need to install it. If it is enabled and installed but it does not work, I recommend reinstalling it with the computer Connect Express app which has on option for that. I also discourage you from trying to put this on an SD card, leave in in the main storage area. The Edge 1030 has 16GB which is plenty and render SD cards pretty much useless anyway. Also keep in mind the map settings are per Activity Profile and not global, so make sure you check the profile you actually use...
