Free Garmin Map of South Africa
This free Garmin map is for MacOSX only and created using data from OpenStreetMap.org. The download is a .dmg disk image and contains the map in gmapi format and will work with Basecamp or Roadmap. The current version is 37.
I build this map from OpenStreetMap data on MacOS X and I use it on my Nuvi 1300. Ensure that you read Garmin manuals for instructions 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.
