Having problem with the CN Europe 2011.40 gmap3d.img file.

I just got a brand new Garmin Nuvi 765T, did all the updates including firmware.
I have CN North America 2010.10 loaded, going to wait 60 days and hope to get a 2012 map with the 1 time free map update.

I have CN Europe 2011.40 on sd card, I also have the JCV file and the gmap3d.img on the sd card.
JCV fille is in sd card Garmin\JCV folder. The gmapsupp.img & gmap3d.img are in Garmin folder.

When I check in maps it shows the CN North America & CN North America 3D.
It also shows CN Europe 2011.40, BUT DOES NOT SHOW CN EUROPE2011.40 3D.

If I rename the file gmap3d1.img, the device tries to read it and states it can't unlock the map.
I was under the impression that gmap3d.img files do not have unlock codes, only map files.
I downloaded the unlocked version of CN Europe 2011.40 and gmap3d.img from this thread.

Anybody have an ides what is wrong?
