How to get maps for my GPS Garmin device?
If you want to use commercial Garmin maps, you probably have to buy them. They are not cheap. But there are a lot of alternatives that will help you with orientation and navigation on your trek. You could download (stolen!) commercial Garmin maps for older Garmin devices (for example Garmin Dakota), but it is not easy to use them in the new Garmin devices such as the Garmin 64 series and newer. I work with the Garmin 64s device. I bought some commercial GPS maps but mostly I work with free map alternatives. This post deals with my favorite GPS map websites.
