No special software required. Should work for Linux, OS X, or Windows, but you’ll need to mount the Garmin device or its SD card to the PC.
Download the map:
- Go to: href=”http://garmin.openstreetmap.nl/
- Under “Choose a predefined country”, pick a map to download from the dropdown lists. You can also select tiles manually from the map by clicking “Enable manual tile selection”.
- Enter your email and click “download map now” or “Build my map”, depending on whether the map exists on the server.
- You’ll receive two emails, the second one containing a link to an HTML page where you can download your map. Go to that page and download a file that looks like osm_generic_gmapsupp.zip.
- Unzip the file to something like gmapsupp.img
Put the map on your GPSr.
- Connect GPS device to your PC and mount the SD card so you can see the card as a drive. This should happen automatically. Or you can put the SD Card in a reader attached to the computer
- Copy the .img file to the drive, into the directory Garmin. Careful not to overwrite anything already there.
- This is what works for the GPSMap 64s:
- Press the Menu button then scroll to Select Map and press Enter.
- Scroll to the map and press Enter twice to enable it. You can also optionally disable other maps while you’re there.
