Download Supplemental Maps to my Garmin Mode Device

Some Garmin Mode devices require a card reader and microSD/SD card in order to download supplemental maps directly from the Garmin website. These devices have a special way to communicate with the computer which will not allow the maps to be loaded directly to the device.

Garmin Mode devices that require this download method include:

  • eTrex Legend Cx/HCx
  • eTrex Vista Cx/HCx
  • eTrex Venture Cx
  • GPSmap 60CSx/60Cx
  • GPSmap 76CSx/76Cx
  • Rino 520HCx/530HCx
  • Astro 220
  • StreetPilot 7200/7500


Once the download has been purchased and is in your myGarmin account, follow these instructions to complete the download process:

  1. Sign in to your myGarmin account (Skip to step 3 if you selected the Add to my Device link from your Order Receipt page)
  2. Click the myMaps tab
  3. Select the Add to Device link for the download
  4. Follow the steps to install the Communicator Plugin if it is not yet installed
  5. Connect a card reader to your computer with a card large enough to hold the download
  6. Connect your device to the computer using a USB cable and power it on
  7. Select the More Options link (refresh the page if this option does not display)
  8. Click the radio button next to your Removable Disk option
  9. Select Continue
  10. Select Accept Agreement after reviewing the Garmin End User License Agreement
  11. Allow the download to complete
  12. Disconnect the unit and card reader
  13. Plug the microSD/SD card into your device

The map will now display on your device. The microSD/SD card must remain in the device when the map is being used.

Note:  You will only be able to add one map download per microSD/SD card with Garmin Mode devices. If you currently have purchased two or more downloadable maps, you will need to use a separate memory card for each map to avoid overwriting the current map on the microSD/SD card.
