In order to save some space you have to create a new "UK-3D Buildings" file every time the CNENTU 20xx.xx is updated.
The created file is about 66 MB so its BIG difference!!!


HOW TO CREATE A SINGLE COUNTRY 3D BUILDINGS FILE

(You need to have Mapsource program and Mapsource version of CN Europe NTU 2015.30 installed on your PC)

1. unlock the original gmap3d.img file
2. on your PC create a folder, ie UK Buildings 3D-2015.30
3. open the unlocked file with Gmaptool
4. use the folder from 2. to split the gmap3d.img file "for Mapsource"
5. Enter UK Buildings 3D-2015.30 as the mapset name and enter a random number for FID (ie 1945) and PID:1
6. Run install.bat from inside UK Buildings 3D-2015.30 folder to install Europe's 3D Buildings on your PC (in Mapsource)
Now the ...tricky part!!!
7. open Mapsource, choose CN Europe NTU 2015.30 from you map list and center UK map at zoom level 200Km (so all UK is on your screen)

Spoiler: .

8. close Mapsource
9. open Mapsource again and the UK map is now centered on your screen (don't close it)
10. open another Mapsource and now choose from your map list the UK Buildings 3D-2015.30 map (you will see nothing on screen-far away zoom level- but your screen is now centered in UK map, like in the first Mapsource)

Spoiler: .

11. in the second Mapsource choose the "Map Tool" and by clicking and dragging the mouse select all the square map tiles that are about UK.
Use the first Mapsource (with NTU 20.15) as reference to which map tile to select on the second Mapsource.

Spoiler: .

This is what I mean "as reference" as I layered up the two screens in Photoshop, all the available UK area is covered properly.

12. in the second Mapsource change Mapsource's "Map Set Name" from default to: CN Europe NTU 2015.30 3D - (UK)
13. send the map to your device or PC or sdCard
14. rename the file name from gmapsupp.img to Buildings 3D - UK.img
15. open the Buildings 3D - UK.img with Gmaptool and press "Change" and in Map name filed enter CN Europe NTU 2015.30 3D - (UK) so the map appears with the right name in the myMaps list on your device (map name=mapset name)



Here is the "UK only" 3D Buildings NTU-2015.30 ready to be copied to your device MAP folder:

Since the 3D Buildings (NTU 2015.30) file is unlocked, it can work OK with any kind of map, not just CN Europe NTU or NT.
It is displayed over any road map in myMaps list!!!
gmap3d.img for NTU is updated 4 times a year but NT is updated only 2 times.
NTU's 3D Buildings is larger than NT's (for UK is 0.4 mb larger).

Sorry but gmap3d.img is usually locked and version dependant, probably you mean gmapdem.img that is unlocked and not version dependant.
gmap3d.img shows cities buildings pictures on map when you zoom in, DEM map shows 3d terrain shadings.
NT and NTU have different FID and different gmap3d with different FID. All addition files are version dependant because they contain their version FID.
This is the reason you must use CNEU NTU if you want JCV.
NT version doesnt provide a working JCV for SP.

Separate jcv files exist and G Express downloads them when users have lifetime for one region only. You cant build them by yourself, but in CNEU threads usually some users post them along separate regions imgs.

For SP JCV from Nuvi 40/50 should work just fine. Inside .System folder you must have a JCV folder and in there just copy xxxxxx.jcv file. Always use the jcv file that comes with the version of NTU you have because JCV is one of these files that are version dependant. For example i use only the Greek part of CNEU NTU 2015.30 and for JCV file i use D3589140A.JCV from the same topic you mentioned at the first post, it works in landscape and portrait also.
