The GPS 155XL’s direct-to function provides a quick method of setting a course
to a destination waypoint. Once a direct-to destination is activated, the GPS 155XL
will establish a point-to-point route line along the great circle from your present
position to the destination and provide steering guidance and navigation data to the
waypoint until it is cancelled. If you are navigating to a waypoint and get off course,
the direct-to function may also be used to re-center the d-bar to proceed to the same
waypoint.
To select a direct-to destination:
1. Press the
D
key. The NAV summary page appears with the destination field highlighted.
2. Use
K
and
O
to enter the identifier of the desired waypoint.
3. Press
E
to confirm the identifier, and
E
to accept the direct-to confirmation page.
To re-center the d-bar to the same active-to waypoint:
1. Press the
D
key, followed by
E
twice. NOTE: If you’re navigating an active approach
with the MAP as the active waypoint, the approach will be cancelled.
A direct-to may also be quickly activated from many pages that display a single
waypoint identifier (e.g., the nearest airport page) by simply pressing
D
and
E
.
For pages that display a list of waypoints (e.g., the user waypoint list page), you must
highlight the desired waypoint with the cursor before pressing the
D
key. Once a
direct-to is activated, the GPS 155XL will provide navigation guidance until the
direct-to is cancelled or the unit is turned off.
To cancel a direct-to destination:
1. Place the cursor over the destination field on the NAV summary page.
2. Press
\
. The destination field will go blank.
3. Press
E
. The GPS 155XL will resume navigating Route 0 (the active route) if available.
