When I downloaded 2011.10 from a torrent site, I had used Haklabs method to install the maps. That involved patched .EXE files and in general was pretty messy. You couldn't upgrade Mapsource or Mapinstall and hope to be able to use the old maps.

When I downloaded 2011.20 from the same torrent site, I again used the Haklabs method. But I received a message telling of an easier way: Using MapReverseConverter and Garmin Unlocker to unlock the files. I swore I would use the combination when I downloaded 2011.30. I did too and it was far easier. Now, instead of having to worry about patched .EXE files and not being able to upgrade, I could simply install 2011.30, convert and unlock the maps, and be done with the entire process.

2011.40 from this site is probably the easiest map conversion I've ever done. Drop an unlocking .EXE into the GMAP directory, run it, and you're good to go once you copy the GMAP directory to where it is supposed to go. The only niggling issue I had was that the installer files were missing. I uninstalled 2011.30 thinking it would retain Mapsource and Mapinstall. Reinstalled 2011.30, ditched its maps, and I was good to go.

If it's this simple, why aren't more people doing the work themselves instead of begging for an .IMG file? Maybe it's me, but while I know quite a bit about the technical side of GPSrs including maps and POIs, there's always more that can be learned. As you see above, as you learn, you find simpler, easier ways of doing things.
