The black box is on the “Route # 1” label. If this isn’t the route you want to
use, press the right or left arrow keys to switch to another one. Before
starting the route, you’ll need to decide if you want to start at the begin-
ning and travel forward or start at the last waypoint in the route and travel
backwards (reverse) to the first waypoint. The default is forward. Next,
highlight the “Start Route” label and press the right arrow key. The screen
shown below appears.
Once you determine which direction in
the route you want to go, you’ll need to
determine the first waypoint in the list
you want to start the route. Usually, it’s
the first waypoint, however the
GlobalNav 310 gives you several options.
The default starting waypoint is the first
one in the list. However, by pressing the
right arrow key, the word “AUTO” ap-
pears in the “Select First WPT” list. This
starts the route with the waypoint that’s closest to your present position.
You can start at any waypoint in the route. As you change the number,
the selected starting waypoint is highlighted on the list.
If you want to see details about the highlighted waypoint, press the WPT
key.
When you have everything on this
screen set as desired, press the ENT
key to start the GlobalNav 310 navigat-
ing to the first waypoint on the route.
As you travel to the first waypoint, the
unit shows navigation data to the way-
point. If you use the plotter, as shown at
right, the unit draws a dotted line from
your starting position (shown by the “S”),
and a dashed line from the first waypoint to each of the other waypoints
in the route. When you enter the radius set by the arrival alarm, the
GlobalNav 310 automatically switches to the next waypoint on the list,
showing navigation data to that waypoint, and so on until the last way-
point on the route list has been reached. (Note: The arrival alarm does
not have to be turned on in order to use the route feature.)
