Thanks for the tip but if the maps are stored at the root level (/Library/Application Support/Garmin/Maps/) or at the user level (~/Library/Application Support/Garmin/Maps/) they are stored as invisible files. I only have one user created for each mac. The is not a container folder in either map folder.
If you cannot see those maps in one of those locations, something is wrong. Those files are not invisible.
Denny I also do not have either of the Basemaps in either of the Library folders. They are however where I stated in my last post.
