I got an online downlown update of City Navigator Mexico 2010. But I think this comes in a diferent format, because I don´t see any .img files installed on my PC. Now I see a folder on Documents and setting/my user/Garmin/Maps/City Navigator NT 2010.gmap/product1/ and inside there are files but with a .gps And the garmin unlocker doesn´t work to totally unlock the maps. Any one has a clue?? Using the keygen of an especific GPS is ok, but the unlocker, nop.
