Geocaching with Garmin Colorado and Oregon

oregon gpsrThe Garmin Colorado and Oregan GPS receivers have been built with geocaching in mind. Their ability to play Wherigo caches and handle GPX files make it a logical unit for geocachers.

But there are a few things to keep in mind when tranferring GPX files into the unit.

When  you connect the GPS receiver to your computer, it should appear as a mountable drive - similar to an external hard or flash memory drive. Double click on the drive to open it and look for the GPX folder - not the Geocache folder. Drag GPX file containing geocaches, typically a pocket query from Groundspeak or Geocaching Australia, into this folder. Eject or unmount the drive from the computer and restart the unit.

If the geocaches in the GPX do not appear, check that you did not copy across a zip file. A Groundspeak pocket query, by default, are zipped. You must unzip these before copying them across.


If the geocaches appear as waypoints, it may be because the 'geocache memory' is full. Depending upon your unit, between 2000 and 5000 geocaches will be stored. The remainder typically appear as waypoints.


Strangely, if you have accidently copied across zip (or other files) the unit will not load the geocaches from the GPX file.

If this occurs, delete all files in the GPX folder of the unit and then copy your GPX across, eject and restart.
