When the window closes i copy the file across the the Garmin folder, reboot and get the cant unlock maps as usual
So, in a nutshell, no it doesnt work

Ok update
At the moment the dos window is still open and the file size is increasing as Its writing, so hopefully this may be actually doing something

Phew - at last - I was able to sort out my problem using image unlocker 1.9 and a 64-bit O/S - if it doesnt update the original file into the unlocked version, just try this:

Right click on the original .img file and go to properties - attributes and see if "read only" is checked, uncheck it. that should do the trick and hopefully it will work. You see, most of the original .img files are write protected by default.

Make sure not to touch the command prompt window of the unlocker and allow it ample time to finish off and close on its own accord. A good way to verify that the result image is the unlocked version is the time/date stamp, it should reflect the one on your computer at the time of unlocking (writing). It overwrites the original and does not create a backup, as suggested by earlier posters. Well, at least version 1.9 doesn't.
