After a lot of tinkering around with map styles, TypWiz3 running on Wine on Mac, and the OpenTopo map repository, I finally managed to get mkgmap to compile a .gmap file that opens on BaseCamp.
Only issue is whenever I try to copy the installed map to my Garmin GPSMAP 64sx, I get the following error from MapInstall:
My device is definitely plugged in, and turned on so I don’t have much of an idea of what’s causing the issue. Only thing that does seem to produce a file usable by MapInstall is if I exclude the .TYP file then everything seems to run correctly but doesn’t get me the map style and .TYP I want.
I ran macOS’s console to see if I could get any more information about the error, only thing I found was this:
Unknown encoding 4294967295
Anyone run into that error before? Any help to get this working would be appreciated!
