A couple of more questions:

1- Let's say I want to remove the GMAPSUPP.IMG file (the small mapset created) on the Garmin and replace it with something else. What's the process? Do I simply delete the IMG using Windows Explorer, or is there a way to do it within Mapsource?

2- There is no GMAPSUPP.UNL file in the Garmin directory. Should there be one?

3- Out of curiosity, how is the unlocked GMAP folder (available for download in Post#1) created? It looks to be one of the subdirectories from the full Mapsource version. Is that all it is? I'm just trying to understand this a little better.

Thanks!!!
I wouldn't change files on the Garmin device. I think it's safer to put new maps on an SD card. You can select regions in MapSource then transfer them on the SD card (you can insert the SD in the Garmin or use a card reader).
