It's been quite a while since I updated my GPS maps, so am wondering if Seppo or csustewy can answer what will undoubtedly be a ridiculous line of questioning.
In investigating mapping options for an upcoming trip down through mainland Mexico, I dug through http://garmin.openstreetmap.nl/
, downloaded the "osm_generic_windows" .exe file, and also the appropriate "osm_generic_gmapsupp" .img file.
Running the .exe placed a bunch of .img files, a .mdx, a .tbr, and an _mdr file into a new "Programs/Garmin/Maps/OSM generic routable" directory.
But the "osm_generic_gmapsupp" which came over is just one big .img file.
So, now what? Do I merely copy the big .img file onto the GPS' SD card, or do I have to do something with the files in the other directory? (There doesn't seem to be an executable in there, so I'm not sure what the next step is if it has to do with those.) Any and all advice appreciated!
