But looks like you still have a problem

Your 3D map should worki in nuvi, if you save it as \.System\gmap3d.img
Path and filename is important in this case, probably you can try \.System\gmap3d1.img too.

For SD card setup you are using different 3D map than recommended in post 4. Follow catymag instructions first, than try your modifications.
