Here is the deal: You have this fancy GPS device but all the software is for Windows. Not so with Garmin GPS devices – their software is fully functional on Mac OS X. I have been able to upgrade the firmware on my Nuvi 710 as well as install updated maps to it.
Project: Bobcat
Bobcat allows you to search for points of interest (POIs), create and organize waypoints, routes and tracks, and easily send them to your Garmin GPS. Bobcat is the Windows equivalent to MapRoute – just a lot prettier.
MapInstall
Allows you to install maps on your Garmin GPS device.
POI Loader
POI Loader is free software for your Mac that helps you upload customized points of interest (POIs) to your compatible Garmin GPS — add the latest restaurants, safety camera locations, tourist destinations and more. You can find the South African POI data here.
WebUpdater
Make sure you’re making the most of your GPS by running our latest software. Check the WebUpdater for the latest firmware release.
Remember to download MapConverter for Windows to convert your unlocked PC maps for use on your Mac
