Warning
The GPSMAP 135 Sounder should not be used as a navigational aid or depth sounder to
prevent collision, grounding, boat damage, or personal injury. The digital depth displayed is
the depth under the back of your boat and not the front. By the time a depth is displayed
most of your boat has already passed over that area. We recommend that you operate the
boat at very slow speed if you suspect shallow water or submerged objects.

Intializing the Receiver
The first time you power up your new GPSMAP 135 Sounder 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 135 Sounder is shipped from the factory in AutoLocate
TM
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 135 Sounder unit and antenna have
been correctly installed on your vessel according to the instructions in Appendix A.
To turn the GPSMAP 135 Sounder 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 system message:
1. Press the Jkey.

The GPSMAP 135 Sounder 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 located at the bottom of the screen. The status bar is used to monitor
the current status of functions such as satellite signal reception, activated alarms, and
also constantly shows the digital depth. A signal strength bar for each satellite in view
will appear on the lower half of the page, 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 glow steadily, and the GPSMAP 135 Sounder is
ready for use.
GPSMAP 135 Sounder Getting Started Tour
The GARMIN GPSMAP 135 Sounder is a powerful electronic navigation and
depth sounding system that provides detailed chart coverage and convenient control of many advanced features right from the screen 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 135 Sounder 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 GPSMAP 135 Sounder’s status 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 135 Sounder’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, let’s put the GPSMAP 135 Sounder into simulator mode.
To place the GPSMAP 135 Sounder in simulator mode:
1. From the status page, press the Okey. The options page will appear, displaying a menu
of options and functions for the status page.

Once the simulator has been started, the status field at the top of the page will
display a ‘Simulating Navigation’ status. Now you’re ready to continue the rest of
the tour. Keep in mind that the GPSMAP 135 Sounder does not track satellites in
simulator mode, and this mode should never be used for actual navigation or to
determine the water depth. All the waypoint and route planning done in simulator
mode will still be retained in memory for future use.
The satellite status page is one of five main pages used in the GPSMAP 135
Sounder’s system. All five pages are linked together in a simple chain, which
allows you to scroll through the pages in either direction using the
J
and
Q
keys. To continue the tour, let’s move on to the next page, the position page.
To scroll to the next page in sequence:
1. Press the Jkey.
The GPSMAP 135 Sounder’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 depth 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 status 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 135 Sounder’s

The sounder page lets you use the GPSMAP 135 as a fishfinder. The top of the
screen contains any of seven selectable data field options, while the middle of the
page contains a right-to-left moving sonar image of the water beneath your boat.
(Note: Items appear on the screen as they pass under your transducer. Those
objects appearing on the right side of the screen are closer to you than those on
the left.) Fish are displayed as a darkened arch or a fish icon in three different
sizes. Thermoclines (layers of water separating warmer water above from cooler
water below) are shown as shades of gray.
The area of strongest sonar return (or whiteline) is displayed as a mix of light
and dark checkering. Typically, the bottom will be the primary source of the
whiteline. A thin whiteline indicates a softer bottom while a thick whiteline shows
a harder bottom. A black line is used to show the point where water meets the
whiteline. This black line will follow the bottom contour, along with any significant objects lying on the bottom. Along the right side of the screen is an
adjustable scale which reflects the depth of the area being displayed. The status
bar at the bottom of the page displays satellite signal status, digital depth, and any
triggered alarms. More on the sounder page may be found on pages 25-35.

The data window, located at the top of the page, provides a user-selectable dis-
play of various navigation data, including course, speed over ground, and 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 21.
Using the Map Cursor
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
R
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 DOWN arrow of the Zkey 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
est 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.
4. Press the
keypad to move the cursor, try following the outline of the lat/lon grid clos-
R
key to remove the cursor and recenter your boat on the map display.
Q
keypad to move the cursor down to the first lat/lon grid
R
As you become more familiar with the cursor, you’ll see that the map display
actively scrolls or ‘pans’, letting you explore areas around the world (even outside
of your current G-chart coverage) and create waypoints and routes. Wherever you
move the cursor, you’ll always be just one
keystroke away from returning the
Q
map to your present position.
Now that you have a feel for how the cursor works, let’s move on and see how
the GPSMAP 135 Sounder 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.

Simulator Setup/Map Scales
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 pages 39 and 81 for more information on map scales
and using G-chart detailed cartography.
Now that we’ve 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
R
move the cursor as close as possible to the waypoint. (To move the cursor in small
increments, try a series of short key presses.)

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 compass tape to indicate your cardinal heading. The
estimated
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 135 Sounder is in simulator mode, you can adjust your
speed and course from the navigation page using the
keypad. As you head
R
toward each waypoint in the tour route, try adjusting your boat speed and course
to get a feel for how the highway works.

The GPSMAP 135 Sounder status 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 45º above the horizon, and the center point a position directly overhead. Use the sky view to determine if there are obstructions shading your
reception of GPS signals.
