Although I think that the above is good advice, I would also like to clarify that NT Maps do work perfectly with the 3490 as well.
I've just recently bought a 3490LMT here in South Africa and the Preloaded Map is CNSA2013.30 NT not NTU.
As I know CNSA NTU doesnt exist. But the default preloaded CNEU map on 3xxx 2xxx and 30/40/50 is CNEU NTU, you cant get NT by Mapudater, like you cant get NTU on 1XXX and old model by Mapupdater till now.

Thanks for your quick response. Indeed I am aware the method described will result in an .img file which still has GMA restrictions. It's just my way of creating a locked .img file via MapSource / MapInstall and then unlocking it at the speed of sound with gimgunlock.

The problem encountered seems to be caused by MapInstall rather than the map itself. I will work through your suggestions and report back with my findings.
Patch new Mapinstall as suggested by Neil
