Garmin BaseCamp software allows users to transfer custom routes from a PC or Mac to a Garmin GPS. Users can import custom routes into BaseCamp in .gdp, .gpx, .kml, .kmz, .loc or .mps formats. The software also allows users to create and modify custom routes using simple and intuitive tools within the program. BaseCamp displays waypoints and routes on a simple basemap of the world to provide a point of reference. After importing and customising routes, users can transfer them out of BaseCamp and into a Garmin GPS unit that is connected to the computer with a data cable.
