The course from one waypoint to the next is a leg. Routes are composed of one or more legs. The legs of all GPS routes are based on straight lines between waypoints.
A route provides the automatic capability to navigate through several waypoints without having to reprogram the unit after arriving at each waypoint. Once programmed into the GPS unit, a route provides the option of navigating forward through the route waypoints or in reverse order (you can even begin navigating in the middle of a route!)
Create and Save a Route
You have the option of creating and editing a route in the unit or you can make a route on your computer with our MapCreate software.
MapCreate is the easiest method for preparing a route, simply because your PC's larger screen, keyboard and mouse are easier to manipulate than the unit.
To load a MapCreate route into the unit, follow instructions in MapCre- ate's manual for creating a route and saving it as part of a GPS Data File (file format *.usr). Copy the GPS Data File to an MMC and insert the MMC in the unit. (See Sec. 2 for instructions on installing MMCs. To load the GPS Data File into the unit's memory, see the entry on Transfer Cus- tom Maps & GPS Data Files in Sec. 6, Basic GPS Operations.)
Routes Created in the Unit
You can create a route by selecting existing waypoints from the way- point list or you can set a series of route waypoints on the map with cursor arrows and the Enter key. In this example, we'll create a route from the map.
