Inexpensive and accurate but about as basic as they come.

Summary: It's ok for what it is but don't expect a lot of fancy features. It seems to be very accurate and batteries last a LONG time. A touchscreen would be a big benefit but you'll pay a lot more for it. I'm in Idaho and both free and purchased Idaho maps work great. But then I downloaded maps for OR & WA.
Less than I expected out of the box (but better after spending more $$).

Summary: Having had a Garmin automobile GPS unit for several years now, I had high expectations when I received the eTrex20 as a gift. What I discovered was that it has very limited usefulness right out of the box: where I live, it shows only major streets, highways, rivers and lakes on a rather nondescript...
Summary: Doesn't seem as user friendly as my Rino 530 Hcx but it probably takes getting used to. I do like the touch screen feature. Both gps and radio work very well in remote areas where I've used them.
Summary: I bought mine in July of 2014.Used it for the MR340.Downloaded the Mo River.Had every wing dike from KC-St.Louis ,the river channel was also downloaded.It worked 100% accurately.Paddled in a fog bank for 36 miles ,looked at the screen of my etrex only.This is a great model and well worth the price.
