In this video, we'll go over the steps required to update the firmware on your Garmin eTrex 20. This will require you to connect your device to your computer and download the update using Garmin's Basecamp and Webupdater.

Make sure you have the latest version of Basecamp & webupdater before you start. This will work on both PC or Mac.

 

 

The recent version of Basecamp now is able to notify you when your device has an update.

1. Plug In your GPS device via the USB connector
2. Open Basecamp, once the application recognizes your device, you will see a notification on the top right of the screen.
3. Click to either update or not

From here Garmin's webupdater will open and will download the software and transfer to your device.

Once done, disconnect the device and manually restart it. This will start the update process, this may take a few minutes.

The device will finish updating the firmware once it restarts on its own and brings you back to the main menu screen.
