osm_generic_gmapsupp.zip.
Move that file to /Garmin/New and extract it there. 7-zip works, most default 'archivers' work for decompressing zip files. After unzipping it, you'll have a file called gmapsupp.img. For the Garmin, you must rename that file to gmapprom.img. This is your new map! Copy it back to your Garmin, re-start it, and take it for a test drive.
Save a copy of your new gmapprom.img in the /Garmin/New folder as the next backup. When it's time, that can be moved to the Old subfolder. But until you're sure everything works okay, keep that old one around!
