The eTrex 20 and 30 is a sturdy GPS unit that is great for all sorts of uses. It runs off of AA batteries so you never have to worry about charging the device or not being able to keep it powered on multi-day tours.

Although there are a couple of feature differences between the two models, the configuration and use of tracks is exactly the same.

    Viewing Cues

  • If you want to see the cues for the route, go to the ACTIVE ROUTE on the main page.

  • This option cannot be disabled.
  • Scroll down and click on a cue to see where it will appear on the map.
  • etrex-active-route-cues
  • Clicking a cue will show you its location on the map, distance to that point, and an ETA.
  • etrex-starting-point-map
  • When viewing the map screen, I recommend the two data fields.
    • Tap the Menu Button on the left side, then select Change Data Fields:
    • DISTANCE TO NEXT – This will tell you how far to the next waypoint.
    • WAYPOINT AT NEXT – This will tell you which cue is next.
  • etrex-map-route

    A couple of pointers about the eTrex.

    • Lithium AA batteries are expensive but will last much longer especially in colder conditions.
    • The screen will stay on, but you can turn of the backlight to save power. Tap the light/power button to see the backlight settings, then use the thumbstick to move the backlight brightness slider all the way to the left.
