highlighted. After reading the warning, press ENTER.

Next, you see the rst of the main pages, the Map Page. The GPSMAP 3205
begins searching for the GPS satellites. The rst time the unit acquires satellites

takes several minutes. Afterward, acquisition times are quicker during normal
use. The GPS status icon on the left side of the status bar shows the progress of
the satellite acquisition process.

GPS icon status colors are:

•

Red—acquiring satellites/lost satellite reception.

Orange—ready for navigation/ready for navigation with WAAS.

•

Gray—lost GPS connection. (Check GPS antenna wiring connections.)

•

The sky view shows a birds-eye view of the location of each satellite relative to
the receiver’s last known location. The outer circle represents the horizon (north
up), the inner circle 45º above the horizon, and the center point a location directly

overhead. You can also set the sky view to a Track Up conguration, causing the

top of the sky view to align along your current track heading.

Status bar

Status eld

GPS Tab

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 green signal strength bars—the receiver has collected the necessary

•
data and the satellite(s) are ready for use.

Receiver Status and Accuracy

The receiver status is shown in the Status eld on the Info sub tab. Current
accuracy is shown in the EPE (Estimated Position Error) eld. Accuracy uses

many factors, such as the number of received GPS satellites, signal strength, and
satellite orientation, to calculate location accuracy in feet or meters. The Status

eld shows one of the following conditions:

• Searching for Satellites

—the receiver is looking for any satellites and

collecting data from satellites visible at its last known or initialized

location, but has not collected enough data to calculate a x. This process
can take up to ve minutes.

Ready For Navigation—at least three satellites with good geometry have

•
been acquired and your location is now being calculated in latitude and
longitude, or at least four satellites have been acquired and your location
is being calculated in latitude, longitude, and elevation. “Ready For
Navigation with WAAS” appears when you are receiving WAAS satellite
corrections in 2D or 3D and a D appears on the strength bar of satellites
being corrected.

After the receiver has collected information from at least three satellites, the

Status eld shows either “Ready for Navigation” or “Ready for Navigation with

WAAS.” The GPSMAP 3205 is now ready for use. Press QUIT to return to the
Map Page.

GPS Setup

The Setup sub tab provides access to functions and features relating to initializing
the GPS receiver.

To access the GPS Setup sub tab:

1. Press and hold ADJ/MENU to open the Main Menu.

2. Highlight the GPS tab, and then highlight the Setup sub tab.

NOTE: When networking with a Garmin GPSMAP 4000 or 5000 series unit,

map data is not shared.

Using the Map Pointer

Use the map pointer to pan away from your current location and scroll to other
map areas around the world (even outside of your current detail coverage). As
you pan past the edge of the map display, the screen scrolls forward to provide
continuous map coverage. The map pointer is an important tool that can be used
to pan to other map locations, mark and edit waypoints and routes, and review
location data of on-screen map items and waypoints.

Map item name, pointer coordinates,

distance, and bearing

To move the map pointer:

Press the ROCKER to move the map pointer in an up, down, left, right, or

diagonal direction.

As you move the map pointer, the distance and bearing from your current
location to the map pointer are shown in the upper-left corner of the map, with
the map pointer’s location coordinates. Keep in mind that when the map pointer
is stationary, the distance and bearing from your present location changes as your
boat moves. The map pointer can also be used to snap to on-screen waypoints
and map items, allowing you to review a selected location directly from the map
display.

To select an on-screen waypoint or map item with the map pointer:

1. Use the ROCKER to move the pointer to the waypoint or map item. When
a waypoint or map item is selected, it is highlighted on-screen with the
name and location shown.

2. Press ENTER to show details of the map item. When using BlueChart or
MapSource data, or if waypoints are grouped tightly together due to the
Range setting, additional tabs appear on the Review Waypoint Page. Use
the ROCKER to highlight the individual tabs to show the information and
additional options.

Navigating to a Destination

Using the NAV key, the GPSMAP 3205 provides four ways to navigate to a
destination—Go To Point, Follow Track, TracBack, and Follow Route. When you
are actively navigating, you see a straight line that always runs from your current
location to the destination on the Map Page. The easiest method for selecting a
destination is the Go To function, which allows you to select a destination point,
and then quickly sets a direct course from your present location. If you highlight
a point on a list or the map and press NAV, Go To <point name> appears in
addition to Go To Point. The Go To function can be accessed from any list of
points or graphically from the map display.

A graphical Go To can be used to select one of three items from the map
display—an existing waypoint, on-screen map items such as rivers, cities,
navaids, or a new map point. If you select a map item as the Go To destination,
the GPSMAP 3205 automatically uses the name of the map item, but the point
is not stored in the waypoint list. If you select a new map point (non-map item)
as the Go To destination, the GPSMAP 3205 automatically creates a waypoint
named MAP at the pointer location.

To Go To an existing waypoint or map item from the map display:

1. Use the ROCKER to highlight the waypoint or map item you want to
navigate to on the Map Page, and press NAV.

2. On the Navigation menu, highlight Go To <waypoint name>, and press

Follow Track and TracBack Navigation

A track is an electronic breadcrumb trail recording or history of your path. The
track currently being recorded is the “active” track. An active track can be stored
in the unit and when stored, is referred to as saved. Both the Follow Track and
TracBack options navigate in the same way. Follow Track uses stored or “saved”
tracks; TracBack uses your current or “active” track.

20 GPSMAP 3205 Owner’s Manual

basIc oPeratIon > navIgatIng to a destInatIon

The TracBack function allows you to retrace your path using the track log
automatically stored in the receiver’s memory, which eliminates the need to store
waypoints along the way. TracBack routes are created by reducing your track log
into a route and activating an inverted route. When active, a TracBack route leads
you through your stored track log points, so it is a good idea to clear the existing
track log before you start your current trip.

TracBack Tips

When a TracBack is active, the GPSMAP 3205 takes the track log stored in
memory and divides it into segments called legs. Up to 300 temporary turns

(BEGIN, TURN 1, TURN 2,...., TURN X, END) are created to mark the most

signicant features of the track log to duplicate your exact path as closely as

possible. To get the most out of the TracBack feature, remember the following
tips:

• Always clear the track log at the starting point.

• The Record Mode option on the track log setup page must be set to
Wrap.

• At least two track log points must be stored in memory to create a
TracBack route.

• If the track log Interval eld is set to

Time, the route may not follow your

exact path (keep the interval set to Resolution for best performance).

• If the receiver is turned off or satellite coverage is lost during your trip,
TracBack draws a straight line between any point where coverage was lost
and where it resumed.

• If your track log’s changes in distance and direction are too complex,
300 waypoints might not mark your path accurately. The receiver then

assigns the 300 waypoints to the most signicant points of your track, and
simplies segments with fewer changes in direction.

DSC uses marine VHF radio and GPS technologies to transmit and receive
location information. DSC is used by mariners for two major operations—distress
calls and position reporting.

For more information about DSC and Maritime Mobile Service Identity (MMSI)
numbers, see page 99 in the “Appendix.”

When the Garmin GPSMAP 3205 is connected to a VHF radio with DSC support,
the GPSMAP 32005 displays a call list, log, and a directory available to store
incoming information received from another user’s DSC-capable VHF/GPS
combination. Basic wiring is required for the Garmin unit and VHF radio to
send and receive NMEA data from each other. See the GPSMAP 3205 & GPS 17
Installation Instructions for more information.

MaIn Menu > dsc (dIgItal selectIve callIng) tab

Understanding DSC Distress Calls

With a Garmin DSC-capable chartplotter properly connected to a VHF radio
featuring DSC output, you can receive any DSC distress call within range. An alert
message appears and an alarm sounds (if enabled) when a distress call is received.
The alarm sounds only for a distress call; position reports do not sound the alarm.
Distress calls are broadcasted to all DSC users in radio range and appear with a
blue and white checkered icon on the DSC tab’s Call List and Log sub tabs.

You can enter a caller’s name, if it is known. The caller’s name replaces the
MMSI number as a reference, when entered.

Review DSC Waypoint

The Review DSC Waypoint Page operates similarly to the Distress Page and
Position Report Page. This page has the additional option to delete the displayed
call. On the DSC Review Waypoint Page, press the Delete soft key to delete the
entry, or press the Create Wpt soft key to create a waypoint.

Understanding Position Reports

The position report operates similarly to the distress call. This type of contact is

like a phone call; no emergency alarms are set off and the call is specic to the

receiver. Position reports are not broadcasted to all DSC users and appear with a
gold boat icon.

Call List Sub Tab

The Call List sub tab shows the 100 most recent calls, even if the unit is left
unattended. You can select any entry from the Call List to show an Entry Review.

Log Sub Tab

When DSC calls are received, they are automatically stored in the log, with
the latest call at the top. The unit can store up to 100 calls; after 100 calls are
received, the oldest is removed when a new call is received.

To review a call or log entry:

1. From the DSC tab, highlight the Call List or Log sub tab.

2. Press up or down on the ROCKER until the call you want to review is

highlighted.

3. Press ENTER.

The Call List and Log sub tabs both show the call Type, Date/Time, Position, and

Review DSC Waypoint

MMSI/Name. Pressing the Sort By (Call) Type, Sort By Time, Sort By Name,

3. Press up or down on the ROCKER to enter information, and press ENTER.

4. Press the OK soft key to save the entry.

After creating a New Directory Item entry, the name created is attached to that
particular MMSI number. If you return to the log, the new name appears under
the corresponding MMSI number.

Setting Up DSC

Use the DSC Setup sub tab to turn DSC on and off. If you have more than one
chartplotter and you only want DSC to show on one chartplotter, turn off DSC on
all but one unit.

You can use the Setup sub tab to simulate distress calls or position reports on this
page while the unit is in Simulator Mode (page 6). Press either the Sim Dstrs
Call or Sim Posn Rpt soft key to simulate a Distress Call or a Position Report.
This is helpful practice before connecting to the real system. The Distress Call
simulator also helps to determine whether alarms are working properly.

Another way to enter a name is from the Entry Review Page or the DSC Distress

a GSD 21 or GSD 22 Sounder Module. Read the installation instructions included
with your Garmin Sounder Module to proprerly install the Garmin Sounder
Module.

NOTE: You must have a GSD 20, GSD 21, or GSD 22 Sounder Module

installed and connected to your GPSMAP 3205 to use the sonar features.

This section provides a general overview of sonar and the things you need to
know to help you use the sonar functionality of your GPSMAP 3205.

Using Dual Beam

Dual beam works best for shallow water (for example, inland) applications.
A dual beam transducer can transmit a narrow or a wide beam. The water area
covered by the transmitted sound waves is determined by the beam width of the
transducer and the water depth. The narrow beam provides crisp detail of what is

under your boat, and is very helpful if you are shing in deeper water where the

beam covers more area (for example, at a 30-foot depth, the narrow beam covers
the area of about a 7-foot circle).

Understanding Sonar

The transducer mounted on your vessel sends sound waves down into the water

in a cone shape, similar to a ashlight beam (covering a smaller circular area at

the top and angling out to a larger circular area at the bottom). These sound waves

reect off of any object that they hit, and then the waves travel back up to the
transducer. These objects could be sh, branches, the bottom, or any other object

that has density that is different from the water. The transducer receives the sound
wave information, and then sends the information to the GSD 20, GSD 21, or
GSD 22 Sounder Module and then to the GPSMAP 3205. The
GPSMAP 3205 displays the information on the screen for you to see and
interpret. The type of transducer and settings that you choose determine how the
information is displayed on the screen.

Narrow

Beam

Wide

Beam

Using Dual Frequency

Dual frequency works best for deep water (for example, off-shore) applications.
The 200 kHz frequency allows you access to great detail about what is underneath
your boat. The 50 kHz frequency provides less detailed information, but
penetrates to greater depths with the same power. You can choose either or both

72 GPSMAP 3205 Owner’s Manual

usIng sonar > understandIng sonar

The wide beam is more helpful in shallow water, because it gives you a much
wider view of objects in the water, including areas beyond the sides of your boat.
At a 30-foot depth, the wide beam covers the area of approximately a 20-foot
circle.

Understanding the Sonar Display

One of the rst things to understand about sonar is that the transducer sends a
beam down to the bottom of the water, much like the beam of a ashlight. The

beam starts small near your vessel and expands as it gets to the bottom.

The Sonar Page does not show a three-dimensional representation of the
underwater environment. Instead, the display is in two dimensions, much like
if you took a picture of an aquarium. Only the depth of the item in the water
is shown. The Sonar display does not show you where an item is located

horizontally in the water, as shown in the following illustrations. The sh is not

directly above the tree in reality, but it can look like it is on the Sonar Page.

The strongest sonar returns appear on your screen as the most intense solid
color (depending on your selected color scheme; red is the default). The weakest
returns appear as the less intense, less solid colors (blue is the default).

The bottom of the water is always going to be the strongest signal, and therefore
the most intense color. The bottom is the continuous, intensely-colored line
running across the bottom of the screen. The GPSMAP 3205 includes the latest

technology in interpreting bottom signals; it can see through sh, structures,
and thermoclines (shown in the weakest colors). Large schools of sh or dense

structures close to the bottom can affect water depth return readings.

At the top of the screen, you might see a grouping of intense colors. This area is
surface clutter, which can be caused by waves or any other sonar interference at

the surface of the water. Too much surface clutter can obscure your view of sh.

You can turn down the Gain setting to reduce this surface clutter.

Between the bottom and the surface clutter, you see sh in the previous
illustration. Here, the sh appear as arches. Actual sh returns might not always
appear as perfect arches, due to the speed, sh orientation, or other conditions.
You can turn on the Fish Symbols setting if you want to see on-screen sh in a
sh shape.

The strength of the sonar return can also help you interpret the hardness of the
bottom of the water. The thicker the bottom line, the harder the bottom.

Hard Structure Soft Structure

NOTE: If the GPSMAP 3205 is unable to track the bottom for any reason, the

digits in the depth window ashes on and off to alert you that the unit is not

tracking the bottom.

GPSMAP 3205 Owner’s Manual 73

usIng sonar > sonar Page

Sonar Page

The Sonar Page is where your GPSMAP 3205 becomes a powerful shnder/
asher. If a GSD 21 or a GSD 22 Sounder Module is not attached, the Sonar

Page appears only when the GPSMAP 3205 is in Simulator Mode or if the Sonar
check box is selected on the System tab.

To view the Sonar Page:

Press PAGE repeatedly until the Sonar Page appears.

The sonar function window contains a right-to-left moving sonar image of the
water beneath your boat. Items appear as they pass under the transducer. The most
recent data is shown on the right side of the screen. The right side of the screen

contains a scale reecting the depth of the area being shown. The top left corner

shows the depth, water temperature, and speed through water (if equipped with a
temperature or speed sensor).

The sonar returns show as red (strongest), orange (strong), yellow (medium), green
(weaker), and blue (weakest). Use the Fish Symbols option to view the actual

sonar data, sh symbols, or a combination of both. Fish symbols appear as red.

When the unit is set to Dual Frequency, the appearance of the sh symbols
changes. Fish symbols from the center of the beam (200kHz) are solid (or narrow
arches), but the returns from the edges of the beam (50kHz) are hollow (or wide
arches).

You can set the sonar display to show a split screen view of a zoomed portion
of the sonar, split frequencies, bottom lock (display scaled from the bottom up)
or a combination of these options. For example, you can choose to show dual
frequency at a 2X zoom (Dual 2X) on one half and normal range dual frequency
(Dual) returns on the other half. The display mode appears at the bottom of each
sonar display.

• Auto Color Gain—controls what colors are applied to the objects on the
screen when the Color Gain option is set to Auto. Color DCG™ is based
on depth and makes it easier to spot subtle changes in bottom conditions
or sh sizes. DynaColor™ (default) represents the latest in sonar data
presentation and is recommended for all applications. The presentation is

based on bottom strength. It makes the bottom and the sh easier to see and

requires fewer adjustments.

• Automatic Scroll Speed Limit

usInG radar

This section covers the features and operation of the GMR 20/40, GMR 21/41,
or GMR 404/406 marine radar when networked with your GPSMAP 3205. Read
the installation instructions included with your Garmin marine radar to install and

congure your GMR 20/40, GMR 21/41, or GMR 404/406.

NOTE: You must have a GMR 20/40, GMR 21/41, or GMR 404/406 marine

radar installed and connected to your GPSMAP 3205 to use the radar features.

Understanding Radar

The Garmin marine radar transmits a narrow beam of microwave energy
in a rotating 360° pattern. When the transmitted energy contacts a target,
some of that energy is reected and returned to the scanner. The scanner
collects the returned energy for processing and display. Your GMR 20/40,
GMR 21/41, or GMR 404/406 is operated and adjusted using controls on your
GPSMAP 3205. You can view radar data on the Radar Page or as an
overlay on the Map Page. All radar controls are accessible from both pages.

When you turn on the radar, the status bar shows the message “Radar Warming
Up” with a countdown to Standby Mode. The countdown also appears in the
middle of the Radar Page. When the countdown reaches 0 (zero), the “Hold
FCTN to transmit” message appears.

As a safety feature, the radar enters standby mode after it warms up. This
gives the operator an opportunity to verify that the area around the scanner is
clear before beginning radar transmission. It is important to remember that the
microwave energy transmitted by the scanner can potentially be dangerous.

CAUTION: The marine radar transmits microwave energy that has the

potential to be harmful to humans and animals. Before beginning radar
transmission, verify that the area around the radar is clear. The radar transmits
a beam approximately 12° above and below a line extending horizontally from
the center of the scanner. Avoid looking directly at the scanner, because the
eyes are the most susceptible part of the body.

When the area surrounding the scanner is clear, press and hold FCTN. The
message “Do you want to begin radar transmission?” is shown. Select Yes, and
then press ENTER.

Before transmission begins, the message “Spinning Up” is shown while the radar
antenna reaches nominal rotation speed. After the message disappears, the radar
begins painting an image.
