Maybe the 'DEM' you are seeing is the in-built DEM on the basemap showing when you zoom out. Please read my previous post again, the EU 3D Terrain DEM works for me as stated. I agree with dasilvarsa, if it's not showing in MyMaps usually it's not active, but don't forget the bug which often will combine and confuse the info if 2 or more DEMs are loaded. To cover all bases, I moved the EU DEM D2249750A.IMG to the unit's .System folder and renamed it gmapdem.img. It's still selectable in MyMaps identifying as 'Europe DEM' and it's working normally. gmapdem1.img should also work in .System folder.Originally Posted by Grumpier
Map identifying as '3D' are 3D building/landmark maps, 3D Terrain maps identify as DEM in MyMaps.
Just so you're clear on what I was saying, the 3D Terrain selection in Map Layers disables DEM totally. The selection in MyMaps is for individually selecting/deselecting separate DEM maps.

Ok, this just gets confusing for me. The D2249750A.IMG I have on my device in the .sys folder, is absoulutely identical to the gmapdem.ing backup file I made when I first switched on the device when I got it.
When comparing both the gmapdem.img file on my backup, the gmapdem.img file Garmin sent me and the D2249750A.IMG I now have on my system they are identical to the last name, info, bit, byte, kb etc. It is safe to say that all three files are one and the same.
On this same thread it was metioned that, all that needs to be done is, to rename the D2249750A.IMG to gmapdem.img, so that the device is able to undersand and interperate the gmapdem.img file so that it shows up in my maps as a map.
As for zooming, the only difference with turning off the map layers as you sugget, is that the detail is less, in terms of shading and depth.
As far as everything else goes the device performs as it did berfore the gmapdem file was renamed.
My concern as to pasting in my original and totally identical gmapdem.img file, is, that havign two identical files, where only one should exist, albeit they have different names, is that this may cause a conflict withing the device. But I dont know enough about the way these programes and files interact.
If I had a spare devcie I would love to play with it and confirm one way or another what is happening. As there are a lot of people out there who believe that he file is gone, or are totally oblivious to anyhting that has happened.
I seek enlightenment and hope I do not appear as argumentative.
