Your full CX NA 2014.10 contains a couple of things:

The street map pieces (equivalent to part of CN NA). Those pieces have FID 2920 and have already been unlocked for all devices.

The MMR (enhanced pedestrian data) pieces. Those pieces have FID 800 and require an unlock code (.unl file) to be used.

In other words --
The MMR (FID 800) components cannot be globally unlocked -- a .unl file is required to use them
The rest of the map (FID 2920) can, and has already been, globally unlocked -- no .unl file is required to use it

Clearer?
