The models etrex 20x/30x have a pre-installed map of Western Europe which supports autorouting providing turn-by-turn directions. These models are equipped with 3.6 GB built-in memory of which 3.3 GB are occupied by the pre-installed map. They also provide support for optional maps and a slot for an optional µSD memory card.
The models etrex 30/30x are additionally equipped with a barometrical altimeter and a tilt-compensated electronic compass. In addition, they can receive signals from a heart rate monitor or a cadence sensor and they support wireless data exchange with compatible devices. All models are well suited for all kinds of outdoor activities such as hiking, biking and geocaching, but they can also be used in vehicles. The display is highly user configurable. Multiple settings can be stored as profiles which allow quick switching between different activities.

Integrated antenna to receive signals of GPS and GLONASS satellites. The accuracy of the position indication gets increased by combining the two systems because there are usually more satellites visible.
Integrated base map with countries of all continents including major cities.
The models etrex 20x and 30x come with a pre-installed map of Western Europe which supports autorouting providing turn-by-turn directions (TopoActive West Europe), see description.
Memory: The etrex 20 and 30 have 1.7 GB built-in memory to store user data and to receive additional, more detailed maps which can be transferred from a PC to the GPS. The etrex 20x and 30x have 3.6 GB built-in memory to store user data and to receive additional, more detailed maps, however, 3.3 GB are occupied by the pre-installed map. All four models are equipped with a slot for a standard micro SD memory card ("TransFlash"). Memory cards are available as an option.
The etrex 30/30x are equipped with an electronic 3D compass to check the heading while not moving¹, accuracy ±5°, resolution ±1°, can be turned off to safe power. "3D" means tilt-compensated compass which does not require the device to be level for accurate readings.
The etrex 30/30x are equipped with a barometrical altimeter for precise elevation recording².
Powered by 2 AA batteries or by an external 12 V power source, e.g. from a car's cigarette lighter (power cord available as an option). Battery life time about 25 h.
Short time to first fix (TTFF³: approx. 15 seconds after a warm start, meaning there are valid coordinates of the satellites available, or approx. 45 seconds after a cold start, meaning there are no valid coordinates of the satellites available).
Supports the american GPS and the russian GLONASS system as well as WAAS (improves accuracy of position indication from typical better than 15 m (49 feet) to typical better than 3 m (10 feet))
Supports more than 100 different datum (coordinate systems)
Supports various display formats include the Swiss Grid
Firmware stored in Flash-Memory, can be updated by the user
Operating temperatures -20 .. 70°C (-4° .. 158°F)
Highspeed USB interface, USB cable for data exchange with PC included)
Dimensions: 54x103x33 mm (2.1x4.0x1.3 inches)
Weight: 140 g (5 ounces)

¹) In order to check the heading with a GPS, a minimal movement with a speed of at least 5..8 km/h (3..5 mi/h) is required. Where no movement is not possible, a compass is needed.
²) Even though a GPS provides accurate elevation information, the value slightly varies continuously. A barometrical altimeter is therefore more accurate, especially when summarizing elevation changes.
³) TTFF: Time To First Fix, time until the first information about the current position is acquired.

Main pages of the GARMIN etrex 10:

The images below show the display of the etrex 10 in true resolution (128x160 pixels). This does not necessarily mean that the display is shown it its true size (36x43 mm). The actual size of these images depends on the properties of your display.

Note: Even if the displays of all three models are basically of the same size, the monochrome pages of the etrex 10 appear smaller than the colored pages of the etrex 20 and 30. This is because the color display has more pixels per square inch than the monochrome display.

Many of the pages are configurable, the pictures shown are just examples. For the data fields, there is a choice of 38 different values, see selection. In addition, many pages support so called dashboards which show some pre-selected values.
