Hi,
I'm having fun playing with my new Montana 600. Is there a way to access the custom maps folder using the Montana unit so I could rename the file extension of some maps in it? I've got several excellent custom maps (kmz format) installed from this site and a couple overlap. Since all the custom maps can only be turned on or off as a group, I've renamed the extension of the map I don't use so often, which disables it. It would be nice to be able to use the Montana to change the file extension back to kmz when I want to re-enable the map.
