5.4 Functions Available When You Follow a Route
5.4.1 Restart navigation
When you follow a route, you can restart
the navigation to the next point on the
route from current location.
When you steer to keep away from an ob-
struction or your boat drifts, you go off
course, like shown with Line 1 in the fig-
ure. If you do not need to return to the
original course, you can go to the desired
point from the current position as shown
in Line 2 in the figure.
Put the cursor on a leg in the route then press the ENT key to show the context-sen-
sitive menu. Select [RESTART] then press the ENT key. The route start position
moves to the current position and the XTE is reset to zero.
5.4.2 Follow a route in reverse order
You can follow the route points of a route in reverse order. This feature is useful when
you want to retrace a route from the end to the beginning.
Put the cursor on a leg in the route then press the ENT key to show the context-sen-
sitive menu. Select [REVERSE] then press the ENT key. The arrows on the route now
point in the opposite direction.
5.4.3 Stop following a route
Put the cursor on a leg in a route then press the ENT key to show the context-sensitive
menu. Select [STOP] then press the ENT key. The arrival area, XTE alarm lines are
erased and the color of the legs connecting the route points of the route changes to
blue.
5.4.4 Skip a leg in a route
When you don’t need to follow all route legs in a route you can skip an unnecessary
leg. (Multiple legs can be skipped) After you select the leg to skip, the route is re-
drawn, with the skipped leg removed. Put the cursor on the route point to skip then
press the ENT key to show the context-sensitive menu. Select [SKIP] then press the
ENT key.
