WARNING!
A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD
TO OBTAIN POSITION INFORMATION.
CAUTION
When showing navigation data to a position (waypoint), a GPS unit will show
the shortest, most direct path to the waypoint. It provides navigation data to the
waypoint regardless of obstructions. Therefore, the prudent navigator will not
only take advantage of all available navigation tools when traveling to a way-
point, but will also visually check to make sure a clear, safe path to the waypoint
is always available.
WARNING!
When a GPS unit is used in a vehicle, the vehicle operator is solely re-
sponsible for operating the vehicle in a safe manner. Vehicle operators
must maintain full surveillance of all pertinent driving, boating or fly-
ing conditions at all times. An accident or collision resulting in damage
to property, personal injury or death could occur if the operator of a
GPS-equipped vehicle fails to pay full attention to travel conditions and
vehicle operation while the vehicle is in motion.

Section 1: Read Me First!
How this manual can get you out on the road, fast!
Welcome to the exciting world of digital GPS! We know you're anxious
to begin navigating, but we have a favor to ask. Before you grab the
GlobalMap3300C and begin installing it, please give us a moment or
two to explain how our manual can help you get the best performance
from your compact, color display, mapping GPS receiver.
First, we want to thank you for buying a Lowrance GPS unit. Whether
you're a first time user or a professional fisherman, you'll discover that
your GlobalMap 3300C is easy to use, yet capable of handling de-
manding navigation tasks. When you team your unit with our custom
mapping software MapCreate6, you have an incredible combination.
You won't find another GPS unit with this much power and this many
features for this price!
Our goal for this book is to get you on the road fast, with a minimum of
fuss. Like you, we'd rather spend more time navigating and less time
reading the manual!
So, we designed our book so that you don't have to read the whole thing
from front to back for the information you want. At the start (or end) of
each segment, we'll tell you what content is coming up next. If it's a
concept you're already familiar with, we'll show you how and where to
skip ahead for the next important topic. We've also made it easy to look
up any tips you may need from time to time. Here's how:
The manual is organized into 7 sections. This first section is an intro-
duction to Lowrance GPS. It tells you the basics you need to know be-
fore you can make the unit look around and tell you where you are.
Section 2 will help you install your unit and the GPS antenna module.
We'll show you how to get the MultiMedia Card (MMC) correctly installed
inside the unit. We'll also tell you about some of the available accessories.
Section 3 covers Basic GPS Operation. It will show you how easy it is to
run the GlobalMap 3300C, right out of the box. This section features a
one-page GPS Quick Reference. (If you've already jumped ahead
and figured out how to install the unit yourself, and you just
can't wait any longer, turn to the Quick Reference on page 40
and head for the road with your GPS unit!)
Section 3 contains short, easy-to-scan GPS lessons that follow one an-
other in chronological order. They're all you'll need to know to find your
way on the water or in the wilderness quickly.

2
After you've learned the basics (or if you already have some GPS expe-
rience), you may want to try out some of the GlobalMap 3300C's many
advanced navigation features. That brings us to Section 4, Advanced
GPS Operations. This section contains the rest of the unit's GPS com-
mand functions, organized in alphabetical order.
When you come to a GPS menu command on the GlobalMap 3300C's
screen, you can look it up in the manual by skimming over the table of con-
tents, just flipping through Section 3 or scanning through the command
portion of Section 4.
This unit is ready to use right out of the box, but you can fine tune and cus-
tomize its operation with dozens of options. We describe how to use general
system options along with GPS options in Section 5, System Setup and
GPS Setup Options. Section 5 is organized in alphabetical order.
In Section 6, we go into more detail on one of the GlobalMap 3300C's
most remarkable capabilities — Searching. We'll introduce a search
example in the Basic GPS Operation section, but there are so many
map items you can search for, we had to give this function its own sec-
tion in the manual! For example, did you know this unit can look up
business phone numbers, functioning as a virtual Yellow Pages? We’ll
show you how in Section 6.
Finally, in Section 7, we offer Supplemental Material, including a list of
the GPS datums used, warranties and customer service information.
Now, if you're into the fine details, glance over the next segment on speci-
fications to see just how much GPS power your GlobalMap 3300C con-
tains. It's important to us (and our power users), but, if you don't care how
many watts of power the unit has, or how many waypoints it can store,
skip ahead to important information on how our GPS works, on page 4.

NOTICE!
The storage and operation temperature range for your unit is from -4
degrees to +167 degrees Fahrenheit (-20 degrees to +75 degrees Cel-
sius). Extended storage or operation in temperatures higher or lower
than specified will damage the liquid crystal display in your unit. This
type of damage is not covered by the warranty. For more information,
contact the factory's Customer Service Department; phone numbers are
listed on the last page.
How Lowrance GPS Works
You'll navigate faster and easier if you understand how the unit scans
the sky to tell you where you are on the earth — and, where you're go-
ing. (But if you already have a working understanding of GPS receivers
and the GPS navigation system, skip on ahead to Section 2, Installation
& Accessories on page 11. If you're new to GPS, read on, and you can
later impress your friends with your new-found knowledge.)
First, think of your unit as a small but powerful computer. (But don't
worry — we made the units in this series easy to use, so you don't need
to be a computer expert to find your way!) The unit includes a keypad
and a screen with menus so you can tell it what to do. The screen also
lets the unit show your location on a moving map, as well as point the
way to your destination.
This gimbal-mounted unit uses an external antenna/receiver module,
which makes the whole system work something like your car radio. But
instead of your favorite dance tunes, this receiver tunes in to a couple of
dozen GPS satellites circling the earth. (It will also listen in to the
WAAS satellites in orbit, but more about that in the upcoming segment
introducing you to GPS and WAAS.)
Your unit listens to signals from as many satellites as it can "see" above
the horizon, eliminates the weakest signals, then computes its location
in relation to those satellites. Once it figures its latitude and longitude,
it plots that position on the moving map shown on the screen. The
whole process takes place several times a second!
The performance doesn't stop there. Stored in the permanent memory
of each GPS unit is a basic background map of the entire world. We lock
it in here at the factory — you can't change or erase this map.
The background map is suitable for many navigation chores, but for
maximum accuracy and much more detail, you need our optional map-
making software, MapCreate6. Some unit features — such as
searching for businesses and addresses — won't work without a custom

5
MapCreate map. There is so much detail in our background map (and
even more in MapCreate) that we'll describe their contents and differ-
ences in Section 3, Basic GPS Operations, on page 27.
Another portion of the unit's onboard memory is devoted to recording
GPS navigation information, which includes waypoints, event marker
icons, trails and routes. This lets you look back the way you came. Think
of this data storage like the hard drive memory in a computer or a tape
in a cassette tape recorder. You can save several different GPS data files,
erase 'em and record new ones, over and over again. Like any computer
file, these GPS Data Files (file format *.usr) can be shared between
other Lowrance GPS or sonar/GPS units, or even personal computers.
This unit has one more thing in common with a personal computer.
Just as computers have a floppy disk drive for storing and exchanging
files, the unit has a slot for an MMC (MultiMedia Card) or SD (Secure
Digital card) flash memory card. These solid-state memory devices are
about the size of a postage stamp, but can hold data ranging from 8 MB
to more than 256 MB in size. (Compare that to a floppy disk's 1.44 MB
capacity!) The unit uses all that MMC space for two key GPS purposes.
First, you can backup your onboard GPS Data Files by copying them to
the MMC. Since the MMC is removable (like a floppy disk or a cassette
tape), you can store these GPS Data Files on a personal computer
equipped with an MMC card reader. (Or store them on a pocketful of
MMCs, if you don't have a computer.) Our MapCreate mapping software
can save, edit or create its own GPS Data Files, which can be copied to
the MMC and then loaded from the MMC into the unit's memory.
(NOTE: No matter where they come from, GPS Data Files must be
loaded from the MMC into memory before the unit can use them.)
The other key GPS use for MMCs is storage of special high-detail, cus-
tom maps, which you can produce on your computer with our MapCre-
ate software. These MapCreate custom maps contain much greater de-
tail than the basic background map. These Custom Map Files (file
format *.lcm) can also be shared between other Lowrance GPS or so-
nar/GPS units and personal computers. (For example, the exact same
MMC, custom map files and GPS data files can be used interchangea-
bly between your gimbal-mounted GlobalMap 3300C and the hand-held
iFINDERGPS receiver.)
You make your own Custom Map Files with our MapCreate software,
but you don't have to. We also sell ready-to-use FreedomMaps. These
custom maps are pre-loaded on MMCs. (No computer work required!).

6
The unit automatically reads Custom Map Files directly from the MMC
or SD card. To use a custom map, all you need to do is slide an MMC
containing a map into the unit.
Introduction to GPS and WAAS
Well, now you know the basics of how the unit does its work. You might
be ready to jump ahead to Section 2, Installation & Accessories, on page
11, so you can mount your unit and plug in the power. Or you might
want to see how our text formatting makes the manual tutorials easy to
skim. If that's the case, move on to "How to Use This Manual" on page
9. But, if you want to understand the current state of satellite naviga-
tion, look over this segment describing how GPS and its new companion
WAAS work together to get you where you're going.
The Global Positioning System (GPS) was launched July 17, 1995 by
the United States Department of Defense. It was designed as a 24-
hour-a-day, 365-days-a-year, all weather global navigation system for
the armed forces of the U.S. and its allies. Civilian use was also avail-
able at first, but it was less accurate because the military scrambled
the signal somewhat, using a process called Selective Availability (SA.)
GPS proved so useful for civilian navigation that the federal govern-
ment discontinued SA on May 2, 2000, after the military developed
other methods to deny GPS service to enemy forces. Reliable accuracy
for civilian users jumped from 100 meters (330 feet) under SA to the
present level of 10 to 20 meters (about 30 to 60 feet.)
Twenty-four satellites orbit 10,900 nautical miles above the Earth,
passing overhead twice daily. A series of ground stations (with precisely
surveyed locations) controls the satellites and monitors their exact loca-
tions in the sky. Each satellite broadcasts a low-power signal that identi-
fies the satellite and its position above the earth. Three of these satellites
are spares, unused until needed. The rest virtually guarantee that at
least four satellites are in view nearly anywhere on Earth at all times.
A minimum of three satellites are required to determine a 2D fix.

7
The system requires signal reception from three satellites in order to
determine a position. This is called a 2D fix. It takes four satellites to
determine both position and elevation (your height above sea level —
also called altitude.) This is called a 3D fix.
Remember, the unit must have a clear view of the satellites in order to
receive their signals. Unlike radio or television signals, GPS works at
very high frequencies. These signals can be easily blocked by trees,
buildings, an automobile roof, even your body.
Like most GPS receivers, this unit doesn’t have a compass or any other
navigation aid built inside. It relies solely on the signals from the sat-
ellites to calculate a position. Speed, direction of travel, and distance
are all calculated from position information. Therefore, in order for the
unit to determine direction of travel, you must be moving and the
faster, the better. This is not to say that it won’t work at walking or
trolling speeds — it will. There will simply be more "wandering" of the
data shown on the display.
GPS alone is plenty accurate for route navigation, but the U.S. Federal
Aviation Administration has special aircraft navigation needs that go
beyond basic GPS. So, the FAA has developed a program to boost GPS
performance with its Wide Area Augmentation System, or WAAS. The
FAA commissioned the system on July 11, 2003.
WAAS is designed to increase GPS accuracy to within 7.6 meters vertically
and horizontally, but it consistently delivers accuracies within 1-2 meters
horizontal and 2-3 meters vertical, according to the FAA. It does this by
broadcasting correction signals on GPS frequencies. Your unit automati-
cally receives both GPS and WAAS signals.
However, there are some fringe areas of the U.S., including parts of
Alaska, that do not yet receive robust WAAS coverage. Continued WAAS
development is planned to extend WAAS coverage in the years to come.
WAAS boosts the accuracy of land GPS navigation, but the system is
designed for aircraft. The satellites are in a fixed orbit around the
Equator, so they appear very low in the sky to someone on the ground
in North America. Aircraft and vessels on open water can get consis-
tently good WAAS reception, but terrain, foliage or even large man-made
structures can sometimes block the WAAS signal from ground receivers.
You'll find that using your GPS receiver is both easy and amazingly
accurate. It’s easily the most accurate method of electronic navigation
available to the general public today. Remember, however, that this
receiver is only a tool. Always have another method of navigation avail-
able, such as a map or chart and a compass.

8
Also remember that this unit will always show navigation information
in the shortest line from your present position to a waypoint, regardless
of terrain! It only calculates position, it can’t know what’s between you
and your destination, for example. It’s up to you to safely navigate
around obstacles, no matter how you’re using this product.

And that's just some of the material available on our web site. To find
out all we have available, go to WWW.LOWRANCE.COM and look around.
For now, though, we'll get back to how to use this particular unit. And,
first, how to use the manual.
How to use this manual: typographical conventions
Many instructions are listed as numbered steps. The keypad and arrow
"keystrokes" appear as boldface type. So, if you're in a real hurry (or
just need a reminder), you can skim the instructions and pick out what
menu command to use by finding the boldface command text. The fol-
lowing paragraphs explain how to interpret the text formatting for
those commands and other instructions:
Arrow Keys
The arrow keys control the movement of dotted cross-hair lines on your
mapping screen called the cursor. The arrow keys help you move
around the menus so you can execute different commands. They are
represented by symbols like these, which denote the down arrow key,
the up arrow, the left arrow and the right arrow: ↓↑←→.
Keyboard
The other keys perform a variety of functions. When the text refers to a
key to press, the key is shown in bold, sans serif type. For example, the
"Enter/Icons" key is shown as ENT and the "Menu" key is shown as MENU.
Menu Commands
A menu command or a menu option will appear in small capital letters, in
a bold sans serif type like this: ROUTE PLANNING. These indicate that you are
to select this command or option from a menu or take an action of some
kind with the menu item. Text that you may need to enter or file names
you need to select are show in italic type, such as trail name.
Instructions = Menu Sequences
Most functions you perform with the unit are described as a sequence of
key strokes and selecting menu commands. We've written them in a
condensed manner for quick and easy reading.
For example, instructions for navigating a trail would look like this:
1. From the Map Page, press MENU|MENU|↓to MY TRAILS|ENT.

10
2. Press ↓to Trail 1|ENT|→to NAVIGATE|ENT.
3. You are asked to wait while it converts the trail into a route.
4. The wait message disappears and the unit begins showing
navigation information along the trail. Now, begin moving and
follow your unit's directions.
Translated into complete English, step 1 above would mean: "Start on
the Map Page. Press the Menu key twice. Next, repeatedly press (or
press and hold) the down arrow key to scroll down the menu and select
(highlight) the My Trails menu command. Finally, press the Enter key."
Step 2 would mean: "Press the down arrow key repeatedly to scroll to
the trail named Trail 1, and press Enter. Next, press the right arrow
key to highlight the Navigate command, then press Enter."

we recommend this installation sequence:
Caution:
You should read over this entire installation section before drill-
ing any holes in your vehicle or vessel!
1. Determine the approximate location for the GPS unit, so you can
plan how and where to route the cables for the antenna and power.
This will help you make sure you have enough cable length for the de-
sired configuration.
2. Determine the approximate location for the GPS antenna module
and its cable route.
3. Determine the location of your battery or other power connection,
along with the power cable route.
4. Install the GPS antenna and route the antenna cable to the GPS
unit's mounting location.
5. Install the power cable and route it to the GPS unit's mounting location.
6. Mount the GPS unit.
GPS Antenna/Receiver Module
This unit's package includes the LGC-2000 GPS module. This device con-
tains the unit's external antenna and receiver for GPS and WAAS signals.
The antenna/receiver module comes with a 25-foot Y-adapter extension
cable. This module can be mounted on a flat surface or pole, or an optional
magnet is available for temporary mounting on any ferrous surface.
The LGC-2000 requires 9 to 20 volts DC power. It draws power through
the unit or from the NMEA 2000 buss (instructions on powering a
NMEA 2000 buss appear later in this section).

GPS Module Installation
The GPS module can be mounted on any flat surface, provided there is
access behind the mounting surface for the screws. The optional mag-
net allows the module to be easily used on cars or off-road vehicles. The
pole mount adapter lets you mount the antenna on a pole or swivel
mount that uses standard marine 1" - 14 threads.
Surface Mount
Tools required for installation are: wire pliers, flat screwdriver, drill, 1"
(25 mm) drill bit and 3/16" (4.75 mm) drill bit.
The GPS module can be easily installed on any flat surface that is at
least 3-1/2" (90 mm) wide. Be sure that a clear, unobstructed view of
the sky is available at the selected location. GPS signals travel "line-of-
sight" at very high frequencies, so nearly anything blocking the an-
tenna can stop the unit from finding a satellite. Caution: Do not mount
in line with a radar antenna. Radar radiates high-energy signals that
can interfere with GPS signal reception.
In an automobile, you may achieve good results by simply placing the
external antenna on the top of the dash, at the base of the windshield. A
piece of the rubber non-skid shelf liner material available in recreational
vehicle supply stores will help hold the antenna in place. This may not
work well if you have a cab-over design pickup truck camper or motor
home. If dashboard reception is poor, simply relocate the antenna mod-
ule elsewhere on the vehicle for a clearer view of the sky.
Once you’ve determined the mounting location, use the template on
page 14 to drill the screw holes. The screws supplied with this unit are
about 1-1/8" long (4mm x 30mm). Drill 3/16" (4.75 mm) holes for the
mounting screws.

13
If you need to route the cable through the mounting surface, drill a 1"
(25mm) hole for the cable's connector. There is a notch in the antenna
housing that allows the cable to pass through to the outside, if desired,
instead of routing it through the mounting surface.
After drilling the holes, pass the O-ring over the cable and press it into
the groove on the bottom of the antenna housing. Now attach the an-
tenna to the mounting surface, using 4 mm screws and the supplied lock
washers. Route the cable (as described later in this section) and the GPS
module installation is finished.
Magnet Mount
A magnet (available as an option) lets you temporarily mount the
GPS module on any ferrous metal surface, such as a car. To use the
magnet, simply peel the backing off the magnet's adhesive coating
and press the magnet to the bottom of the antenna housing. The
module is ready for use.

Pole Mount
The GPS module attaches to the pole mount
adapter with the supplied 4 mm screws.
You can route the cable through the slot in
the side of the module and down the side of
the pole. Or, you can pass it down through
the pole mount adapter and run the cable
inside the pole. The 1"-14 threads on the
pole mount adapter accept a standard
marine antenna mount.

After the module is installed, connect it to the unit. The LGC-2000 can
communicate with your GPS unit either directly (using the supplied ex-
tension cable) or through a NMEA 2000 network.
Connecting Directly to the Unit
After the module is installed, attach it to the end of the Y-adapter ex-
tension cable as shown in the following diagram. To connect it to the
unit, insert the extension cable's splitter plug into the Network socket
on the back of the unit and your system is ready to use.
