The only link for an image in Post #1 is for the 3D building map, gmap3d.img. The only detail map dl available in P#1 is for the gmap folder which of course is quite a bit larger than the image. 2,756,951,323 bytes compared to 2,025,357,312 bytes [~1.88626 GB or 1931.53125 MB].

To answer your question, yes the gmap3d.img will work with the matching corresponding version NA detail map as long as it's unlocked too and regardless of the source of either.
