Duplicate maps on my XT

[lkraus]

If it helps, this is what my (fully updated) XT has in zūmo XT\Internal Storage\.System\Map

I examined the files in Notepad++ to determine their contents.

zūmo XT\Internal Storage\Map is totally empty.

There are no .unl files anywhere on my XT or in the various Garmin directories on my PC. Results of a Google search says these are "Backup files created by MapSource, a program used to manage maps for Garmin navigational devices; contains unlock codes for maps; used as a backup copy so that the codes can be restored back to the Garmin device.May 5, 2010"
All the references I'm finding only mention their use with Mapsource, so I'm not sure they are still necessary unless perhaps you use that program.

.unl files are needed on many devices and it is not connected to MapSource. The .unl files may not be needed on some of the latest Garmin devices though, including the XT.

I assumed .unl = unlock codes but we all know about the work ass-u-me. Regardless, I have them in multiple places on my XT as well as will the map files on the PC for BaseCamp.

lkraus, thanks for you directory listing. I am on a trip now, typing this while at a hotel. I look forward to comparing your list to mine when I get home.
