Adding additional maps and using a microSD card are frustrating

Summary: The Garmin Etrex 30 has been very useful to me in my charting of World War One and World War Two battlefields. I can't give it four or five stars, though, because I find Garmin's system for downloading and loading additional map materials too onerous. My primary work takes place in France, so I spent the $250 or so to buy the French topographic maps on CDROM and the $30 or so to get the downloadable BirdsEye data for the areas I'm interested in in France.
Excerpt: I got it as a hiking aide for my trip to the adriondikes. It does what its supposed to. Does not lose coordinates like most other devices.My only gripe is with garmin charging me 80 $ a year for their maps service. I didnt do my research before buying it, but if you do you should plan for this cost as well.
Incredibly tight fit with carabiner clip; returned.

Summary: I got one with the associated belt clip, and I was very unimpressed with construction quality. I have a Garmin 62st as well. Compared with the 62st, the Etrex 30 mounting rail in the back is plastic, and it had a really poor fit with the carabiner clip I also ordered. Once the two were mated, I had great difficulty in separating the two.
Be sure to search for open source maps before you buy them from garmin.

Summary: This unit is night and day above any car-based GPS I've ever used. Tons of functionality, great accuracy, and performance. The ability to load custom tracks, routes, and maps from the internet is fantastic as well. I like the form factor (no antenna sticking out), and the screen is very readable in pretty much any conditions. The interface is intuitive and easy to use unless you're trying to type in city or street names, in which case it's pretty time consuming.
Garmin Etrex 30 - An excellent GPS but fickle to get started

Summary: My first experience with the Garmin Etrex 30 was not a pleasurable one as I had problems updating the software from off the shelf 3.50 to 3.90. Once I learned the trick things went smoothly. In order to update the software one needs to make sure they select the unit's internal memory before starting. The new user will need Garmin's Webupdater and communicator plug in. After that the process goes well.
Summary: i use this for capturing GPS locations and then transferring that information into computer software that calculates radio path reliability. It is difficult to get the information out of the device so that I can enter it in my computer without either getting the unit setup so it can see the satellites while I retrieve waypoints.
Summary: I love my Garmin eTrex 30. It has met my expectations alynd gone beyond them. I use it mainly for geocaching, but I have used it just for directions. I know there are still things that it will do that I have yet to discover, but as of right now, I'm completely satisfied with my purchase and it is worth the price.
eTrex 30 - Great GPS. One dead pixel right in the middle of the screen.

Summary: This would be a five star product except for two points: 1) I got one with a dead pixel in a bad location. 2) Even with the latest software upgrade and after a few years of being out, occasionally an app crashes. I've only had the whole GPS crash and restart once. With that being said, this GPS really is amazing. The ability to add custom maps via KMZ is just friggin outstanding.
