INTRODUCTION

Keypad Usage

The GPSMAP 230’s advanced keypad system is designed to allow for fast, convenient selection of navigation options and data entry.

The Getting-Started Tour will introduce you to most of the keypad and provide a “hands-on” lesson in using the GPSMAP 230. We strongly encourage you to take the Getting-Started tour before using your unit for actual navigation.

The GPSMAP 230 Quick Reference Card contains helpful tips on using the unit and performing various navigation tasks. It’s a good idea to keep the Quick Reference Card nearby whenever you’re navigating with your new GPS chartplotter.

Initializing the Receiver

The first time you power up your new GPSMAP 230 is an important step in getting the best possible GPS performance. The receiver must be given an opportunity to collect satellite data and establish its present position. To ensure proper initialization, the GPSMAP 230 is shipped from the factory in AutoLocate

mode, which will allow the receiver to “find itself” anywhere in the world. To speed up the initialization process, we recommend using the graphic initialization process described below, which will usually provide a position fix in about a minute.

Before you initialize, make sure the GPSMAP unit and antenna have been correctly

installed on your vessel according to the instructions in Appendix A.

To turn the GPSMAP 230 on:

1. Press and hold the Pkey until the power tone sounds.

The welcome page will appear while the unit conducts a self test. Once the internal test is complete, the mariner’s warning will appear, asking you to read and acknowledge important information regarding the proper use of electronic charts.

To acknowledge the mariner’s warning:

1. Press the Tkey.

A message alert and prompt will also appear to ask you to select an initialization method.

To view a message:

1. Press the Jkey.

2. Press the

key again to return to the previous page.

GETTING STARTED

Initialization

A. The welcome page will be displayed while the

unit performs a self-test.

B. Confirm the mariner’s warning before start-

ing navigation. Remember that the electronic chart is designed as a supplement to local government charts, not as a replacement.

GETTING STARTED

Initialization

The select initialization window will appear, with the ‘select from map’ option

highlighted.

1. Press Tto initialize the receiver from the built-in worldwide map.

The Map Page will appear, prompting you to select your approximate present posi-

tion with the map cursor.

1. Use the Rkeypad to move the map cursor to a location close to your present position. If you have difficulty identifying your exact position, press the scale.

I key to zoom in to a lower map

A. Use the arrow keypad to move the cursor to a

location close to your present position.

B. Hollow signal strength bars will appear on the

Satellite Page while the receiver collects satellite data.

2. Press

to confirm your selection.

The GPSMAP 230 will now begin searching for the appropriate satellites for your present position and should acquire a fix within a minute or so. While the receiver searches for satellites, a flashing satellite icon will appear at the left-hand side of the status bar. A signal strength bar will also appear for each satellite in view, with the appropriate satellite number under each bar. The progress of satellite acquisition is shown in three stages:

• No signal strength bars— the receiver is looking for the satellites indicated.

• Hollow signal strength bars— the receiver has found the indicated satellite(s) and is

collecting data.

• Solid signal strength bars— the receiver has collected the necessary data and the satellite(s) is ready for use.

Once the receiver has collected information from at least three satellites, the flashing satellite icon on the status bar will quit flashing and remain solid, and the GPSMAP 230 is ready for use.

Now that the unit is initialized, let’s turn the unit off and then begin the GettingStarted Tour.

To turn the GPSMAP 230 off:

1. Press and hold the Pkey for about 3 seconds, until the screen is blank.

GPSMAP 230 Getting-Started Tour

The GARMIN GPSMAP 230 is a powerful electronic charting/navigating system that provides detailed chart coverage and convenient control of many advanced features right from the map display. This tour is designed to take you through the basic pages and functions of the system using the simulator mode. Once you’re familiar with the main pages and functions of the unit, refer to the reference section for instructions on performing specific tasks and functions.

The Getting-Started Tour assumes that the receiver has been properly installed and initialized, and you have not changed any of the default unit settings. If you have changed any settings (position formats, units of measure, etc.), the descriptions and pictures in the tour may not match your configuration.

To turn the GPSMAP 230 on:

1. Press and hold the Pkey until the power tone sounds. The welcome page will appear while the unit conducts a self test.

2. Once the self test is complete, press the

key to acknowledge the mariner’s warning.

The Satellite Page will appear, and the receiver will begin to acquire satellites. From the Satellite Page, you may also quickly adjust the screen contrast and backlighting.

To adjust the screen contrast:

1. To increase the screen contrast, press the right arrow of the

2. To decrease the screen contrast, press the left arrow of the

The GPSMAP 230’s three-level screen backlighting is controlled with Pkey, and may be adjusted at any time from any page.

GETTING STARTED

Power On & Screen Contrast

A. The screen contrast may be adjusted from the

Satellite Page by pressing the ARROW KEYPAD. Press EDIT/ENTER to confirm changes.

B. Whenever the screen backlighting is on, a bulb icon

will appear in the status bar at the bottom of every GPSMAP 230 page.

To turn on and adjust the backlighting:

1. Press the Prepeatedly until the backlighting is at the desired level (off, 1, 2, or 3).

Indicators

The GPSMAP 230’s Satellite Page provides a visual reference of satellite acquisition and receiver status, with a signal strength bar graph and a satellite sky view in the center of the page. Each page of the GPSMAP 230’s system also features an options page, which gives you access to other functions and features that relate to the specific page you are viewing. To get a feel for how the options pages work, lets put the GPSMAP 230 into simulator mode.

To place the GPSMAP 230 in simulator mode:

1. From the Satellite Page, press the Okey. The options page will appear, displaying a menu of options and functions for the Satellite Page.

2. Use the UP or DOWN arrow of the and press

3. Press the

key to confirm the simulator warning.

keypad to highlight the ‘Start Simulator?’ option

Once the simulator has been started, the status field at the top of the page will display a ‘Simulating Navigation’ status, and you’re ready to continue the rest of the tour. Keep in mind that the GPSMAP 230 does not track satellites in simulator mode, and should never be used for actual navigation. All the waypoint and route planning done in simulator mode will still be retained in memory for future use.

The Satellite Page is one of four main pages used in the GPSMAP 230’s system. All four pages are linked together in a simple chain, which allows you to scroll through the pages in either direction using the

and Qkeys. To continue the

tour, let’s move on to the next page, the Position Page.

Compass Tape

To scroll to the next page in sequence:

1. Press the Jkey.

The GPSMAP 230’s Position Page shows where you are, what direction you’re heading and how fast you’re going. The compass tape at the top of the page indicates the direction you’re moving. The four user-selectable data fields below the compass tape show your current course and speed over ground, along with a resettable trip odometer and altitude display. Your current latitude and longitude, along with a 12/24-hour clock, appear at the bottom of the page.

Now that you’ve seen how the Satellite and Position Pages can be used to monitor satellite acquisition and your present position, let’s take a minute to learn how to mark and store our present position as a waypoint. (Since we’re in simulator mode, the present position displayed will be the last position calculated by the receiver, which should be the spot where you’ve initialized the unit.) This will also give you an opportunity to see how the GPSMAP 230’s

The waypoint is now stored in memory. Note that waypoints may also be created directly from the map display or by manually entering position coordinates. Both of these techniques are described in the reference section of the manual and/or on your GPSMAP 230 quick reference guide. To continue our tour, let’s move on to the Map Page.

1. Press the Jkey.

The GPSMAP 230’s Map Page combines digital chartplotting with a user-selectable display of navigation data and a built-in worldwide database to 64 nm. It will also be the page you use most to create and edit waypoints and routes. Before we take off on our practice route, let’s take a brief look at its various features and displays.

GETTING STARTED

Map Page

The map display, located in the middle of the page, shows your boat as a tri- angle marker on an electronically generated chart, along with geographic names, markers and buoys that are provided by the G-chart cartridge you’re currently using. It also displays your track, routes and nearby waypoints. An on-screen cursor lets you pan to other map areas, determine the range and bearing to a position, and perform various waypoint and route functions.

The data window, located at the top of the page, provides a user-selectable display of various navigation data, including course, speed over ground, and the bearing and distance to the cursor or a particular waypoint. The status bar, located at the bottom of the page, displays the current map scale setting, as well as the status information described on page 17.

A. To select an on-screen waypoint, simply move the

cursor over the desired waypoint. The waypoint/navaid name and position, along with the bearing and distance from your present position, will be displayed.

B. The map page can also be configured to display

additional data fields and a graphic course deviation scale or compass. See page 26 for more on map options.

Using the Map Cursor

GETTING STARTED

Using the Map Cursor

A. Whenever the cursor is active, the bearing and

distance of the cursor from your present position will appear in a pop-up data window.

B. To remove the cursor and recenter your vessel on

the map, press the QUIT key.

Working from the Map Page is a simple process that centers around the use of the

cursor. Controlled by the

keypad, the cursor is an important tool that can be

used to pan to other map locations, mark and edit waypoints and routes, and review position data of on-screen navaids and waypoints.

To get a feel for using the Map Page and using the cursor, try the following

exercise:

1. Use the I key to set the map scale to the 64 nm setting. Your boat should be near the

center of the map, at the receiver’s last known position (if your boat isn’t where it should be, make sure that you have initialized the receiver and acquired a position as described on pages 1-2).

2. Use the DOWN arrow of the south of your boat’s position.

3. Using the to your boat. Notice how another data field appears at the top of the page, showing the bearing and distance from your boat to the cursor, along with the lat/lon of the cursor.

Now that you have a feel for how the cursor works, let’s move on and see how the GPSMAP 230 works on the water. To help you practice using the Map Page and other features, we’ve stored a practice route in the receiver’s permanent memory, so you can see exactly what you’ll experience when you’re navigating with your new GPS chartplotter.

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 part— going to a destination. The above the

GETTING STARTED

Simulator Setup & Map Scales

A data field at the top of the page will now display the bearing and distance to the second route waypoint. To get started, let’s enter a speed for our vessel, which we can do from the ‘Setup Simulator?’ listing on the options page. The setup sim-

ulator page is also available from any other page in the main page sequence.

To enter a boat speed:

to finish, and Jto return to the map display.

Once a speed has been entered, you’ll notice that the map will begin to move slowly, keeping your boat centered on the display. To get a better view of what’s going on, zoom in to a closer map scale.

1. Press the I key to select the 16 nm scale.

A. To enter a boat speed or define the simulated

course, highlight the ‘Setup Simulator?’ option and press EDIT/ENTER.

B. Enter a boat speed of 60 knots to begin the tour.

This will allow you to complete the GettingStarted Tour in 10-15 minutes.

You’ll now have a clearer picture of the route we are navigating, along with an outline-only presentation of the surrounding shoreline. Because the usable range of the built-in database is only valid to 64 nm scale, we no longer have full cartography available. Keep in mind that whenever you do exceed the usable range of the built-in database or the G-chart cartridge in use, the range field will display ‘OVR ZM’ or ‘NO MAP’ to indicate that you should exercise extreme caution using the cartography data. See page 25 and 66 for more information on map scales and using G-chart detailed cartography.

Now that we’re zoomed in a little closer to our route, we can pan ahead of our vessel with the cursor to review and create on-screen waypoints and navaids. Try moving the cursor to select the ‘TOUR3’ waypoint— just use the

keypad to

move the cursor as close as possible to the waypoint (to move the cursor in small increments, try a series of short key presses).

Once the cursor is over the TOUR3 waypoint, you’ll notice that the waypoint symbol and name will become highlighted, and the data field at the top of the page will display the waypoint name, the range and bearing from your present position, and the coordinates for the waypoint.

To review the waypoint page for a selected waypoint:

1. Press the Tkey.

2. To return to the Map Page, press

again.

Reviewing & Creating

Waypoints on the Map

The cursor can also be used to create new waypoints right from the map display.

To create a new waypoint using the cursor:

1. Use the Rkeypad to move the cursor as close as possible to the following position: N 35º 02.129’; W 076º 26.106’ (use the data window to verify the cursor position).

The Navigation Page provides graphic steering guidance to your destination. The bearing (BRG) and distance (DIS) to the destination, with your current course (COG) and speed over ground (SOG), are displayed at the top of the page, along with a graphic compass to indicate your cardinal heading. The esti- mated time enroute (ETE) and velocity made good (VMG, or the rate you are closing in on your destination) are displayed at the bottom of the page.

As you head toward the destination, the middle section of the page gives you visual guidance to your waypoint on a graphic highway, which displays the route and nearby waypoints on screen. The moving arrow below the highway always points to the destination waypoint relative to the direction you’re moving. The line down the center of the highway represents your desired track, while the bottom of the page provides a graphic indication of your crosstrack error (the distance and direction you are off course) according to the scale at the bottom right of the page.

Whenever the GPSMAP 230 is in simulator mode, you can adjust your speed

and course from the Navigation Page using the

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 Rkeypad to increase the speed in 5 knot/kph/mph increments. 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 Rkeypad.

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 setting 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 Ior Hkey (OUT to increase, IN to decrease the scale).

The Navigation Page data fields may also be configured to display any of ten different navigation values. Let’s change the VMG field to crosstrack error to provide a digital readout of the distance we’re off course.

The GPSMAP 230 Satellite Page provides a visual reference of various receiver functions, including current satellite coverage, receiver operating mode and current receiver accuracy. The status information will give you an idea of what the receiver is doing at any given moment.

The sky view and signal strength bars give you an indication of what satel- lites are visible to the receiver and whether or not they are being tracked. The signal strength is shown on a bar graph for each satellite, with the satellite number below. When a satellite is visible but not being tracked, the strength bar will not be shown and the sky view indicator will not be highlighted.

The sky view shows a bird’s-eye view of the position of each satellite relative to the receiver’s last known position. The outer circle represents the horizon (track up), the inner circle is 45º above the horizon, and the center point is a position directly overhead. Use the sky view to determine if there are obstructions shading your reception of GPS signals.

Signal Strength

Indicators

A. Whenever the GPSMAP 230 is searching for satel-

lites, no signal strength bars will appear.

B. Once the receiver has found the satellite(s) indicated,

a hollow signal strength bar will appear. After satellite data has been collected, the signal strength bars will become solid.
