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 obstruction or your boat drifts, you go off
course, like shown with Line 1 in the figure. 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.

you want to retrace a route from the end to the beginning.

sitive menu. Select [REVERSE] then press the ENT key. The arrows on the route now
point in the opposite direction.

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
