First of all the map that you have linked above as torrent is fairly old - you'd better take this: [Only registered and activated users can see links. ]
Second: forget SD card ID, MapID, gmapsupp.unl etc.!
You only have to unlock the downloaded img with unlocker like gimgunlock or unlocker alternative, which you can all find here in software section.
...may there always be one hand's breadth water beneath your keel
