Garmin eTrex

This page provides a quick guide of all steps recommended to test our products on Garmin eTrex series. We believe these steps should also be similar to ones to use on Garmin Montana and Oregon devices.

These steps are by no means required. You may peruse the other pages on this site and transfer the files as you see fit to your device. However, they present one good way that we believe should work.

We welcome your feedback about alternate & better ways to improve on loading the data to the unit.

Information below was created on 26 April 2015 using the Garmin eTrex 30 with software version 3.40 and a Mac computer using OSX 10.10.4. Screens and menu options may change with different software releases.

Find Data

  1. The file you download when you purchase GPX data is a compressed ZIP file.

  2. Expand that file on your computer to retrieve all the individual GPX files contained within it. To expand the file, double-click on it or choose to Open it from the menu.

  3. Depending on the package you purchased, it will contain the GPX data in a number of GPX files that have ".gpx" extension. These may be in multiple folders when you purchase all sections for an entire route.

  4. Read and agree to the GPX Data Agreement file included.

Service Points

The eTrex can store up to 2,000 service points at one time. None of the routes that we have published so far exceed this number for the entire route.  However, if you are combining routes, keep this limit in mind.
