There is a note in the "Manage Maps" of Garmin Express that says maps can be transferred (presumably from the 67i) to a computer for use in Basecamp. I don't know if this is new. It would be convenient for planning to work on Basecamp without the 67i attached by USB. Is the way to transfer the maps documented somewhere? Does someone know how to do it. From Windows Explorer the maps appear to be image files with associated files of the same filename but with a different extension.
