Although it took me a little while to warm up to the idea of using a GPS, once I got one, I found them almost indispensable. This walkthrough is my basic workflow on getting a .gpx file into my eTrex 20.
As much as the eTrex is a great piece of hardware, it’s software onboard, as well as on my Mac is a little, well, rough. I won’t shy away from the fact that I was still trying to figure out how to use the darn thing, when I was lining up a few years ago to give the AZTR a go. Since then, I’ve gotten a bit better in making it work for me (rather than against). So enjoy the how-to, and maybe I’ll be lucky enough to give the AZTR another go next year.
