OK... done ! They are unlocked.

I started over from scratch. Used JM to generate a new unlock code and transferred the maps and JCV, 3d files etc.

I also deleted all the img files prior to transferring maps.

After maps were transferred, I looked and saw the new;y transferred maps were saved on the 765 as gmapsupp.img and NOT as gmapprom.img. Weird.... but I made an unlock file with the name gmapsupp.unl.

There is not a gmapprom.img on the unit, but it seems to be working OK.

I still note that there are still TWO gma files on the unit.

Thanks for all the help.
