TracBack Tips (cont.)
¥ If the receiver is turned off or you lose satellite coverage during your trip, the TracBack
route will simply draw a straight line between any point where coverage was lost and
where it resumed.
¥ If the changes in direction and distance of your track log are very complex, 30 waypoints
may not be enough to accurately mark your exact path. The receiver will then assign the
30 waypoints to the most significant points of your track, and simplify segments with
fewer...

Route Definition Page
The last form of navigating to a destination with the GPS II
+is by creating a user-defined
route. The GPS II+lets you create and store up to 20 routes of 30 waypoints each.
The route navigation feature lets you plan and navigate a course from one place to anoth-
er using a set of pre-defined waypoints. Routes are often used when itÕs not practical, safe, or
possible to navigate a direct course to a particular destination (e.g., through a body of water
or impassable...

Route Definition Page (cont.)
The right side of the route definition page features several ÔfunctionÕ 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 thatÕs currently in route 0, be sure to copy it to another
open route, as it will be overwritten by the next route activation.
Routes can be copied, cleared, inverted, and activated...

Activating and Inverting Routes
After a route has been entered, it can be either activated in sequence or inverted
from the route definition page. The process of activating or inverting a stored route
takes a storage route (routes 1-19) and copies it into the active route (route 0) for
navigation. The storage route is now no longer needed and will be retained in its
original format under its existing route number.
This system allows you to have an active route that you may edit during...

Active Route Page
Once a route has been activated, the active route page will display the waypoint
sequence of your route with the estimated time enroute (ETE) at your present speed
and the distance to each waypoint (Fig. 50a). As long as you are navigating an active
route, the active route page will become part of the main page sequence of the unit.
The active route page will also allow you to change the ÔeteÕ field to display desired
track (DTK) or estimated time of...

On-Route GOTOs
At the beginning of this section, we mentioned that the GPS II
+will automatical-
ly select the route leg closest to your position as the active leg. This will give you
steering guidance to the desired track of the active leg. Note that the first waypoint
selected as the destination waypoint will be of the route leg closest to your present
position. This may mean youÕre not navigating to the first waypoint in the active
routeÑyou may be navigating to the...

with a rotating compass display to show your direction of travel (Fig. 54a). The
