Install Map Links onto a MAC

Please also refer to our USER GUIDE for Downloadable links for MAC, under our FAQ category for Tutorials & Videos.

Rather use Google Chrome or Mozilla Firefox to download the GPS Maps as we have found that the file is corrupt when you use Safari internet browser.

Please follow the steps below:

  1. Click on the link (T4A Map).
  2. The link will download immediately on your internet browser.
  3. Once done, click on the zip file. The file will extract and your downloads folder will open listing the gmapi file. .
  4. Double click on the gmapi file. Garmin MapManager will open  with a small window in front of it (if you don’t see it then move the Mapmanager window, as it might be located behind it). Click on install and then close.
  5. The map will now be listed on the Garmin Mapmanager program and installed on your Macbook.
  6. Open BASECAMP and select the map/s to view under maps at the top of the toolbar.
