The good news is that if you own a Garmin GPS device, there’s a way to get free Garmin GPS maps. And in most cases, the free maps are much better than the expensive Garmin maps. I’m a big fan of Garmin GPS devices, but I always found it disappointing that they charged extra for maps. Garmin doesn’t publicize it, but most of their GPS units are setup to take any maps in the correct format. Here’s how to get and install these free hiking maps in an easy, step-by-step process.
