Hi. I tried installing the locked mapsource version in my folder C:\Garmin but it was not recognized by Mapsource. I then installed it in C:\Documents and Settings\All Users.WINDOWS.0\Application Data\GARMIN\Maps (I use Windows XP) and it worked. I tried unlocking it using the "All" MS DOS batchfile that I had from before but Australia & NZ 2012.1 map was not showing on the list of files to be unlocked. I tried the Garminunlocker.exe file but that also didn't work. I'd really appreciate any help on how to unlock this map. Thanks all
