I am not so good in text so excuse me for my dyslectic head, to much text here
I want to instal a downloaded map from openstreetmap, i have “OSM generic routable.gmap” and a “gmapsupp.img”
i want to instal it to a 16 Gb micro sd card in my GPSmap 62s.
I have a macbook pro os-x 10.11.6
i instaled Basecamp, Express, Mapinstall and mapmanager on my mac.
Now i have an old map i want to delete but i don’t know how.
I did it befor but now i feel lost.
ps, if this is at wrong place, excuse me for my ignorence.
