[. . . ] If there are temporary waypoints stored in routes 1-19, the receiver will create any new temporary waypoints using the first three-digit number available. TracBack Navigation The TracBack feature will navigate your track log back to the oldest point in the receiver's memory. The track log will be divided into segments with temporary waypoints to create a route back to the beginning of the track log. 28 Creating and Navigating Routes The last form of navigating to a destination with the GPS 120XL is by creating a user-defined route. The route navigation feature lets you plan and navigate a course from one place to another using a set of predefined waypoints. Routes are often used when it's not practical, safe or possible to navigate a direct course to a particular destination (e. g. , through a body of water or impassable terrain). Routes are broken down and navigated in smaller segments called "legs". The waypoint you are going to in a leg is called the "active to" waypoint, and the waypoint immediately behind you is called the "active from" waypoint. The line between the "active to" and the "active from" waypoint is called the "active leg". REFERENCE Route Navigation Waypoint 2 ("active to" waypoint) "Active Leg" Waypoint 1 ("active from" waypoint) Whenever you activate a route with the GPS 120XL, it will automatically select the route leg closest to your position as the active leg. As you pass each waypoint in the route, the receiver will automatically sequence and select the next waypoint as the "active to" waypoint. 29 REFERENCE Route Definition Page The GPS 120XL lets you create and store up to 20 routes of 30 waypoints each. Routes are created, copied and edited through the route definition page, which is accessed through the Menu Page. To select the route definition page: 1. To return to the Menu Page, press J. Route Number Leg Distance Defining a Route If you're heading out without a planned route, the mark function can be used to quickly create a route back to your starting point. Create a series of waypoints along the way with the MARK key and save them to an open route from the mark position page. When you're ready to head back, simply activate the route you created in inverted order (see page 32). Comment Field Desired Track of Leg Copy Field Total Route Distance Function Prompts The route number field is displayed at the top of the page, with a 16-character user comment below. If no user comment is entered, the field will display the first and last waypoint in the route. The waypoint list in the middle of the page accepts up to 30 waypoints for each route, with fields for desired track and distance between legs. The bottom of the route definition page features several function fields which let you copy, clear, invert or activate the displayed route. Routes 1-19 are used as storage routes, with route 0 always serving as the active route you are navigating. If you want to save a route currently in route 0, be sure to copy it to another open route, as it will be overwritten by the next route activation. 30 To create a route from the route definition page: 1. (Note that the default [first and last waypoint] comment will only appear if the comment field is blank. ) 4. Continue entering the rest of your waypoints in order, using the F key to start and confirm each field entry. After you have entered all your waypoints, press J. REFERENCE Creating, Copying & Clearing Routes Copying and Clearing Routes The route definition page is also used to copy a route to another route number. This feature is useful when you make changes to the active (or TracBack) route and want to save the route for future use. Scroll through the available routes and select a destination route number. Press the J key to return to the Menu Page. Enter each waypoint in the order you would like to navigate them.
