Dear all,
I hope I am in the right sub forum.
I have downloaded as well various OSM Maps as img file. When I load them into basecamp they just have a generic name like OSM_map. How do I change this to differentiate them in Basecamp and on my Garmin, please?
It is not very helpful if all maps have the same name in the Garmin menu.

Thank you for your help!
Best regards
B
