Now, why did I go through all the trouble? Why didn't I just wait for someone else to post their Mapsource files? Well, someone did post the Mapsource files, but I went through all this trouble because my current Nuvi has lifetime map updates and to me it was critical to be able to use the map set I downloaded from Garmin.
This apparently is not the case, if my experience with 2012.10 is any indicator. In my reading of it, it appeared that using Map Reverse Converter and the Garmin Unlocker would remove GMA authentication. I however read this thread late at night and it just didn't read right to me. In attempting to install the 2012.10 maps on my device I encountered the GMA authentication error.
