Garmin is a company that puts out GPS devices. GPS stands for "Global Positioning System." These devices help you to navigate to a particular area using GPS maps. If you have a BitTorrent file with the extension ".torrent" for Garmin maps, you won't be able to access the maps themselves until you use the BitTorrent program to download the maps to your computer using the Torrent file.
Download and install BitTorrent (see Resources).
Right-click on your Torrent file. A drop-down appears. Select "Open with."
Click the "BitTorrent" option. The program now opens and begins downloading the Garmin maps to your computer.
