I will post the results.
As the *.unl from the uploaded card will not be the correct ones (not generated with the CID of your card) this will not work.

From what we know so far when the card is inserted for the first time the *.gma and *.unl files will be read processed and then deleted
Also the GarminDevice.xml will be created during that process.

I assume that the *.unl files could be re-created with information from the GarminDevice.xml, however I have no Idea about the *.gma files.
