Unlocking to GPSmap276c

Hi Guys.
I have downloaded City Navigator N.A.2011.40 and Europe 2012.20 .They are in Mapsource and I can view them on the P.C.no problem.I can select them, send them to my GPS it loads them, then imforms me that the map set needs to be unlocked.Here lies the problem.
The maps appear in mapsource and show that the maps are "not lockable" how ever there is no provision given to unlock the maps to the device serial number
Thanks for some help

If MapSource is unlocked you not need device id anymore.. it works almost all devices
