Do not recommented to use country(ies) files with whole region files at the same time.

In torrent at bottom are DEM files downloadable through iGO NextGen from GooglePlay Store.

Basemap.dem should be recognized, but premium DEM usually require license.
You don't need premium, use USA_83_CGIAR_081010.dem .
Larger DEM (premium) slows device.

I am not sure if there is a conflict if you put few DEM of same region, but if you have standard DEM, you don't need basemap.

I started with only USA_CGIAR_Premium_2006.06_090313.dem and then put this in my sys.txt file:
[map]
3d_buildings=1
3d_landmarks=1
3d_dem=1 ; 3D terrain
3d_dem_detail=3 ; detail of 3D terrain (0 = none, 1 = low, 2 = medium, 3 = high)

But it does not work. I have iGo Primo 9.6.13.405512. When I look in content while in the iGO Primo, I can see that the .dem file is recognized and active. Please let me know what I am doing wrong.

If under About->Content it showed (and not red), then it's not licensing issue. Do this
Put only one at a time under the content/dem/ directory and see if it show correctly
If it does show correctly under various zooms, select the one you see* best. Generally "premium" is better, but not always. For DEM only the following is relevant
3d_dem=1
3d_dem_detail=1 ; start with low and go up

* NNG DEM's are just eye candy, no other data (such as elevation value nor contouring lines) are shown. No data are used to help aid in navigation.

Here is the DEM file for South America. Check if Cuba is part of it. I'm not sure, since Cuba is part of the caribbean, but I never saw a DEM file for this region.
