Selecting a GOTO Destination
The GPSCOM 170 provides four ways to navigate to
a destination: GOTO, MOB, TracBack and route naviga-
tion. The most basic method of selecting a destination is
the GOTO function, which lets you choose any stored
waypoint as the destination and quickly set a direct
course from your present position.
To activate the GOTO function:
1. Press
G
. The GOTO waypoint list, an alphabetical
list of all available waypoints, will appear.
2. Select the waypoint you want to navigate to (it may
already be highlighted).
3. Press
E
to confirm, or
Q
to stop selection of
a GOTO destination and return to the previous page.
Once a GOTO waypoint has been activated, the
GPSCOM 170 will provide steering guidance to the des-
tination until either the GOTO is cancelled or the unit
has resumed navigating the active route (see page 46).
To cancel an active GOTO:
1. Press
G
.
2. Use the arrow keypad to move the field highlight to the
‘CANCEL GOTO?’ prompt at the bottom of the page and
press
E
.
Man Overboard Function
The GPSCOM 170’s man overboard function (MOB)
lets you simultaneously mark and set a course to a posi-
tion for quick response to passing positions (like the spot
where your hat blew overboard).
To activate the MOB mode:
1. Press
G
twice. The GOTO waypoint page will
appear with ‘MOB’ selected as the default destination.
2. Press
E
to begin MOB navigation.
The GPSCOM 170 will now guide you to the MOB
waypoint until the MOB GOTO is cancelled (see “cancel
GOTO” above). If you want to save the MOB waypoint,
be sure to rename it, because it will be overwritten the
next time a MOB is executed.

Select a destination way-
point from the GOTO
waypoint list.
Once the MOB mode has
been activated, steering
guidance will be provided by
the compass or highway
page. Activating another
MOB will overwrite the pre-
vious MOB waypoint.
