TomTom truck original map

Hey
I have tomtom original truck map on sd card. I have many tomtom go9000 devices. If i put original map in sd card to the device then it works evry device no need to activation.
But if i made a copy and then put that copy to the device then it does not work.
What is the secret abot this.
Is possible to make original sd card copy what will work also?

What is the proble. Other devices are in different countries in truck cars and i cant get them. It easy to make truck map what will work only that device Device ID and tmeta code but is possible to make same good copy to original SD card what will work.

Problem is the same as for Carminat I would say.
If you check the map folder you might find a .mct instead of a .dct.
This means the map is locked to the serial number of the SD and this number can't be changed.
So an original SD works on all devices, a copy on none.
