Summary: I bought and took back a ETREX 20 from a local store. The map that comes with it only shows Interstate roads and bigger state highways. No secondary or township roads. If lost you would find your way to a big road.
Summary: My opinion - too complicated. I returned it. Having said that, if I understood all the "hiking language" and knew how to plan trips using a paper map and compass, probably this would work. Guess I'm just used to "Google Maps" and a TomTom GPS in the car and maps on my smart phone.
Summary: I'm not new to GPS devices; I've had a few in my day and know the basic ins and outs. But I've spent a month on Garmin's website and forums trying to learn how to use this thing and still can't figure it out. Most of the functionality requires using the Garmin software - "Basecamp".
Summary: I really don't like touch screens so I opted out of the Dakota series. Wish I wouldn't have. The knob for controlling the interface is annoying as all get out. Can't operate it while wearing gloves and it activates while in my pocket (really garmin? no button lock?).
Summary: I was expecting a better screen. If you have a smart phone, go to download a hiking app and you will happy with a nice screen and very easy to use. Maybe you would prefer to buy a good water-proof case for your phone, auxiliary battery and free app.
Summary: This is a nice little toy. But be prepared to buy, or subscribe to buy, maps. The map shown on the unit in all the sales literature does NOT come with the it. All you get, out of the box, is a blank screen with a few lines on it. They call that the "base map.
Cannot get it to attach to my handlebars without slipping ...

Summary: Cannot get it to attach to my handlebars without slipping round, despite trying as is, and with a bit of old tubing to pad it out a bit. The ball joint can be tightened so that it doesn't rotate. Also sits quite high, which doesn't work so well if you're long-sighted and riding low.
