Free Garmin Map of South Africa
This free Garmin map is for MacOS X only and is created using data from OpenStreetMap.org. The download is a .dmg disk image and contains the map in .gmapi format that will work with Basecamp. The current version is 43, built 2015-11-23.
I build this map from OpenStreetMap data on MacOS X and I use it on my Nuvi 1300 and Dakota 20. Ensure that you read Garmin manuals for instructions on installing maps as I can take no responsibility for anything that might go wrong. If you find any errors in the map consider joining OpenStreetMap.org and contributing to the map.
