eTrex 20 takes one of the most popular and reliable GPS handhelds and makes it better. Redesigned ergonomics, an easier-to-use interface, paperless geocaching and expanded mapping capabilities add up to serious improvements for an already legendary GPS handheld. eTrex 20 is versatile. It's tough. And it's built to handle whatever Mother Nature can dish out – and more.

eTrex 20 features paperless geocaching by supporting GPX files for downloading geocaches and details straight to your unit. Visit OpenCaching.com to start your geocaching adventure. By going paperless, you're not only helping the environment but also make your geocaching much more fun. eTrex 20 stores and displays all the information you need including location, terrain, difficulty, hints and descriptions, which means no more manually entering coordinates and paper print outs.

See The Way

eTrex 20 has an enhanced 2.2 in 65K colour, brilliant, sunlight-readable display. Durable and waterproof, eTrex 20 is built to withstand the elements. It has an upgraded interface yet retains its legendary toughness to withstand the elements – be it dust, dirt, humidity or water, none of which are a match for this navigator.

Add Maps

With its microSD™ card slot and 1.7 GB of internal memory, eTrex 20 lets you load our range of Ordnance Survey maps such as Garmin GB DiscovererTM and hit the trail, plug in BlueChart® g2 preloaded cards for a great day on the water or City Navigator NT® map data for turn-by-turn routing on roads (see maps tab for compatible maps). eTrex 30 also supports BirdsEyeTM Select map download service, that lets you download premium raster maps to your device and integrate them with your existing maps.


Keep Your Fix

With its high-sensitivity, EGNOS-enabled GPS receiver and HotFix® satellite prediction, eTrex locates your position quickly and precisely and maintains its GPS location even in heavy cover and deep canyons.

Go Anywhere

With an array of compatible mounts, eTrex 20 can be used on your bicycle, boat, in your car or motorbike and off-road vehicle. You even get turn-by-turn directions with the auto mount and City Navigator NT® maps. Wherever you think you might take eTrex, it has the mapping and mounts to get you there.

Go Global

The new eTrex series is the first-ever consumer-grade receivers that can track both GPS and GLONASS satellites simultaneously. GLONASS is a system developed by the Russian Federation that will be fully operational in 2012. When using GLONASS satellites, the time it takes for the receiver to "lock on" to a position is (on average) approximately 20 percent faster than using GPS. And when using both GPS and GLONASS, the receiver has the ability to lock on to 24 more satellites than using GPS alone.

3.0 out of 5 stars Needs improvement 31 Mar 2012
By Mike
Style Name:Standard
Ok I have had Garmins for as long as I can remember. My trusty old Etrex Hcx is still going strong and my wife has an Oregon 450T, which is a great piece of kit. Yes, the base map supplied sucks, so shop around on certain internet auction sites for a cheap Garmin Discoverer. The Etrex 20 needs a few things to make it a 5 star rating.
1:- The screen is flush with the body, not recessed so its likely to be damaged (a screen protector could help with this)or scratched.
2:- No lock button so there is a danger you could knock the little joystick on the front and add waypoints or do something you wouldn't expect and run the batteries down.
3:- Sticky!!! Its probably best to search on You Tube for "garmin sticky" for an excellent demo on this problem, which is yet to be addressed fully by garmin, basically the unit may not register distances under certain speeds when navigating(geocaching etc)

Hope this helps

I have given Garmin a quite a bit of money over the years, therefore I am entitled to lead my review with something negative. Yes, the build and the reliability of their handheld models (of all colours) keeps me coming back (this is my third different model), but why, why, why do they decide that the unit basemaps should always be so rubbish?

Turn on the machine and not only do you get a crude drawing of the major routes around about (in other words, NOT what is on the box cover!) but it can't even get the name of the nearby river right (The Ouse not The Swale)! No matter indicating where I might cross without getting wet! Like buying a new luxury car with a warped steering wheel and a sticky gearbox and being told items which works properly are extra!

(So Garmin do the right thing - give us a free decent map for the price (or ten quid more) and stop being so penny pinching. Also put the first set of batteries in the box too. I've bought a five pound clock that bundled them!)

Negatives (which I knew in advance) out of the way you have a good piece of kit in the eTrex 20. Good hard-knock protected case and a healthy signal that hasn't failed me in any outdoor location. Locks on satellites before you even leave the house (well for me anyway). Will work even deep in a bag and new batteries last all day. Indeed, if you search out the free maps on the internet and download them - a very improved piece of kit over previous models.

(I personally employ some second-hand card Garmin maps which I got on the cheap. I'd buy new card maps if I went on holiday somewhere. Note the mini-SD goes under the batteries which needs to be slide locked.

5.0 out of 5 stars Destined for classic status 5 April 2012
By Col
Style Name:Standard|Verified Purchase
If the Garmin eTrex Series of GPS's had been capable of displaying OS Mapping before now I would never have purchased any other GPS handheld as they are superb little devices.

Because of this previous lack of mapping capability I purchased a Satmap Active 10 and later a Garmin GPSMAP 62S.

Both units were capable of displaying OS Maps, and each had its merits.

Unfortunately the Active 10 was useless in bright sunlight, and needed constant access to a Nuclear Power Station in order to provide the energy to run it, while the GPSMAP 62S was the size and weight of a house brick.

What I needed was a GPS that combined the following:

1. Compact and lightweight design
2. Screen clarity in bright sunlight
3. Low battery consumption
4. Ability to display OS Mapping

I purchased the eTrex 20 a few days ago, and after taking it out of the box my initial thought was that it was a toy - based purely on the weight of it compared to my GPSMAP62S.

After that ridiculous assumption I really scrutinised the new gps.

The build quality is truly superb. The casing did not creak when I pressed the power on button, as it does on my GPSMAP62S. Aesthetically and ergonomically it really does take some beating. All the edges are rubberised, making for very secure handling. It is so well designed that you really can operate it with one hand.

The menu structure is intuitive, and within thirty minutes you should have a good understanding of how the unit operates.

The eTrex 20 not only uses the American GPS Satellite System but also the Russian `GLONASS' system, which logs your location very quickly.

It is also EGNOS enabled.

Wasn't he that kid on Britain's Got Talent?

3.0 out of 5 stars Good in theory, annoying limitations in practice 5 July 2012
Style Name:Standard
This is my first GPS, that I bought seven months ago. I use the eTrex 20 for cycling, geocoding photos and geocaching. I used an iPhone for these things before. I generally like the GPS - it has a good screen, that is often usable without the backlight, and the geocaching functionality is ok. Unfortunately, there are some problems that make daily use annoying:

* The GPS is slow to render maps. This is especially obvious during panning and zooming, which I ended up doing a lot in practice (since zooming out gives little detail, zooming in requires a lot of panning). Sometimes I have to wait seconds to view the full map.

* It does not have a USB 2.0 interface, which makes transferring maps to the GPS slow. New maps are often one or two gigabytes, transferring an updated map image often literally takes hours. Updating maps is something you have to schedule. Garmin's maps are not updated that often, but if you want to upgrade OSM maps monthly, beware!

* The joystick is nice for controlling the GPS. But when you put the device in your pocket, it's often pressured too much, resulting in random actions.

* The base map is crude and limited. It only serves as a demonstration and a global overview. Other than that it's unusable for any hiking or cycling. Garmin's maps usually come at 100 or 200 Euro a pop per country. If you live in Euro, one can easily spend hundreds of Euros to get the topo maps for hiking. Luckily, there is Openstreetmap, which can be downloaded freely. But coverage and detail differs per country and region.

* The user interface is confusing. It's better than most other brands of GPSes that I tried. But it's still not as good as it could be.
