GETTING STARTED

Using the Navigation Page

Whenever the GPSMAP 180 is in simulator mode, you can adjust your speed

and course from the Navigation Page using the R keypad. As you head toward

each waypoint in the tour route, try adjusting your boat speed and course to get a

feel for how the highway works.

To adjust the simulated boat speed:

1. Press the UP arrow of the

keypad to increase the speed in 5 knot/kph/mph incre-

ments. Press the DOWN arrow to decrease the speed in the same increments.

To steer the boat:

1. Press the LEFT and RIGHT arrows of the

keypad.

Notice that as you get off course, the highway and waypoint pointer move to

give you graphic guidance to get back on course. The base of the highway display

also serves as a graphic course deviation indicator (CDI), relative to the scale set-

ting shown at the bottom right of the page. The scale setting represents the total

distance (or the width) of the base of the highway display. The default graphic

highway setting is 1/4 nm, but can be set for a 1/2-, 1-, 2- or 4-nm range.

To change the highway scale display:

1. Press the

key (ZOOM OUT to increase, ZOOM IN to decrease the scale).

The Navigation Page data fields may also be configured to display any of ten

different navigation values. Lets change the VMG field to crosstrack error to pro-

vide a digital readout of the distance were off course.

To change a data field:

1. Press the

key to display the Navigation Page options.

2. Highlight the Change Data Fields? option and press

. The field highlight will now

appear in the top-left data field (the BRG field).

3. Use the

keypad to move the field highlight to the VMG field and press

4. Highlight the XTE option and press

, and press

to finish.

A. To reset the simulator to steer the desired

course automatically, select the Auto COG set-

ting from the options page.

B. The highway scale can be set to a 1/4-, 1/2-, 1-,

2-, or 4-nm/mi/km range with the ZOOM keys.
