Selecting a User-Defined Navigation Page
Once you’ve selected a GOTO destination or activat-
ed a MOB or route, the GPSCOM 170 will provide graph-
ic steering guidance to the destination with one of two
navigation pages:
•The highway page (the default navigation page) pro-
vides a graphic highway that shows your movement
relative to the desired course, with an emphasis on
your crosstrack error,(the distance and direction you
are off course.) The highway page is well suited for
boating and other activities with higher speeds and
straight–line courses to a destination.
•The compass page provides a directional pointer to
the destination, with a rotating compass graphic to
display your direction of travel. The compass page is
ideal for activities like trawling or entering a harbor,
and provides better steering guidance for slow-
speed (e.g., walking) travel with many
directional changes.
Both pages provide a digital display of the bearing
and distance to the destination, your current speed and
track over the ground, and course deviation indicator
(CDI). You can select the desired navigation page at
any time.
