During the Garmin Express Update to City Navigator Europa NT: 2021.20 the gmapdem.img file was removed, is there a link where I can download the .img file?
You actually prompted me to check the status week past I updated my nuvicam to this release...!
My unit reports this map (Europe DEM in my case, or: D224900B.img) as present so all is good and nothing got lost.
To tell you the truth I'm not exactly sure why this file got replaced with the latest release in the first place as it's exactly the same one as supplied in the past. From GMapTool:
Reading file D:/Install/Win/Apps/Garmin/GARMIN/Maps/2021.30/D224900B.img.

I cannot provide you with any links I'm afraid - I'm sure it can be found on the Interwebs - but if you get stuck, send me a PM and I will try to help...
I have img available, in my case:

But how can I export from this img the gmapdem.img?
Ah, fair point.
But the above refers to EU maps rather than DEM map. I believe DEM map was in separate folder under C:\ProgramData\Garmin\CoreService\Downloads\Map.
Try to browse there - can't tell you where exactly as I deleted its content once I updated my unit lasts week.
