Getting Started
Using the NAV Key
Going to a Destination
GPS is all about marking positions as waypoints and navigating to them using the receiver’s
steering guidance and map displays. We’ve already seen how to use the
ENTER/MARK
key to store
your present position, so it’s time to move on to the fun part—going to a destination.
The
NAV
key, located on the keypad above the
QUIT
key, is the primary tool used to select a
destination waypoint, TracBack, or a route to navigate. The
NAV
key can be used in two primary ways:
• Pressing
NAV
once displays a list of options from which you can select ‘Go To Point’, ‘Follow Route’,
‘Follow Track’, or ‘Stop Navigation’.
• Highlighting an on-screen waypoint or map item as a destination directly from the Map Page and
pressing
NAV
allows you to graphically select points to “Go To”.
For our simulated trip, you’re going to select a pre-programmed tour route using the fi rst method.
This will also show how the
MENU
key is used throughout the GPSMAP 188/188C/238 Sounder
system to provide tab style options and functions. Let’s start by changing the position to where the
practice route is located.
To change the GPSMAP 188/188C/238 Sounder position in simulator mode:
1. Press the
MENU
key twice to display the list of Main Menu tab items.
2. Use the
ARROW KEYPAD
to highlight the ‘Systm’ tab.
3. Highlight ‘Set Position’ in the simulator setup window and press
ENTER
.
4. From the Initialize Position page, press the
MENU
key. With ‘Enter As Text’ highlighted, press
ENTER
.
5. On the Enter Position window, press
ENTER
then use the
ARROW KEYPAD
to enter N34°56.800’,
W076°24.066’ and press
ENTER
when done, then press
QUIT
to return to the Map Page.
Text entry for
simulator position.
For future practice, you
may skip steps 3 through
5 and use the
ARROW
KEYPAD
to point to a
location from the Initialize
Position page.
