A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD
TO OBTAIN POSITION INFORMATION.
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 waypoint, but will also visually check to make sure a clear, safe path to the waypoint
is always available.
When a GPS unit is used in a vehicle, the vehicle operator is solely responsible for operating the vehicle in a safe manner. Vehicle operators
must maintain full surveillance of all pertinent driving, boating or flying 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
two to explain how our manual can help you get the best performance
from your compact, wide-screen, 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 4800 is easy to use, yet capable of handling demanding
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:
4800 and begin installing it, please give us a moment or
The manual is organized into 7 sections. This first section is an introduction to Lowrance GPS. It tells you the basics you need to know before 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 4800, 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 35
and head for the road with your GPS unit!)
1
Section 3 contains short, easy-to-scan GPS lessons that follow one another in chronological order. They're all you'll need to know to find your
way on the water or in the wilderness quickly.
After you've learned the basics (or if you already have some GPS experience), you may want to try out some of the GlobalMap 4800's many
advanced navigation features. That brings us to Section 4, Advanced
GPS Operations. This section contains the rest of the unit's GPS command functions, organized in alphabetical order.
When you come to a GPS menu command on the GlobalMap 4800's screen,
you can look it up in the manual by skimming over the table of contents,
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 customize 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 4800'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 section 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 specifications to see just how much GPS power your GlobalMap 4800 contains.
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.

How Lowrance GPS Works
You'll navigate faster and easier if you understand how the GlobalMap
4800 scans the sky to tell you where you are on the earth — and, where
you're going. (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 it easy to use, so you don't need to be a computer expert to find your way!) The GlobalMap 4800 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 GlobalMap 4800 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 the GlobalMap 4800 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 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.
4
The background map is suitable for many navigation chores, but for
maximum accuracy and much more detail, you need our optional mapmaking software, MapCreate 6. Some unit features — such as
searching for businesses and addresses — won't work without a custom
MapCreate map. There is so much detail in our background map (and
even more in MapCreate) that we'll describe their contents and differences in Section 3, Basic GPS Operations, on page 31.
Another portion of the GlobalMap 4800'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 Lowrance GPS or sonar/GPS units or even personal computers.
This GlobalMap 4800 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!) This 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 GlobalMap 4800 can use them.)
The other key GPS use for MMCs is storage of special high-detail, custom maps, which you can produce on your computer with our MapCreate software. These MapCreate custom maps contain much greater detail than the basic background map. These Custom Map Files (file
format *.lcm) can also be shared between Lowrance GPS or sonar/GPS
units and personal computers.
This 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 GlobalMap 4800.

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 GlobalMap 4800 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 8. But, if you want to understand the current state of satellite navigation, 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 24hour-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 available 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 government 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 locations in the sky. Each satellite broadcasts a low-power signal that identifies 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.
6
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 satellites to calculate a position. Speed, direction of travel, and distance
are all calculated from position information. Therefore, in order for the
GlobalMap 4800 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 automatically 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 consistently 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
7
receiver is only a tool. Always have another method of navigation available, such as a map or chart and a compass.
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.
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 following 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
MENU.
ENT and the "Menu" key is shown as
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 this 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.
8
For example, instructions for navigating a trail would look like this:
1. From the Map Page, press
2. Press ↓ to Trail 1|
ENT|→|↓ to NAVIGATE|ENT.
MENU|MENU|↓ to MY TRAILS|ENT.
3. You are asked to wait while it converts the trail into a route.
4. The wait message disappears and the GlobalMap 4800 begins
showing navigation information along the trail. Now, begin
moving and follow your GlobalMap 4800.
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 and then the down arrow key to highlight the Navigate command,
then press Enter."

Section 2:
Installation & Accessories
Preparations
You can install the GPS system in some other order if you prefer, but
we recommend this installation sequence:
Caution:
You should read over this entire installation section before drilling 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 desired 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.
5. Install the power cable and route it to the GPS unit.
6. Mount the GPS unit.
GPS Antenna/Receiver Module
This unit's package includes the LGC-2000 GPS module. This device
contains 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.
LGC-2000 Module, bottom view (left) and top view (right).
11
You need to select an antenna installation location that has a clear, unobstructed view of the sky. After the module is installed, connect it to
the end of the Y-adapter extension cable as shown in the following diagram. To connect it to the unit, insert the cable's splitter plug into the
Network socket on the back of the unit and your system is ready to use.
(When looking at the back case, the left socket is for the power/data
cable and the network socket is second from left.) See the module's instruction sheet, publication part number 988-0147-791, for complete
installation directions.

NOTE:
The second plug on the extension cable’s Y-adapter will have a 60ohm terminator attached to it. Do not remove this terminator.
You must leave the terminator connected to this socket at all times
for your antenna/receiver to function correctly.
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 module elsewhere on the vehicle for a clearer view of the sky.
Power Connections
Your unit comes with a power/data cable that splits into three ends,
each with several exposed wires (shown in the following figure). The
end with 4 wires (blue, yellow, orange and shield) is a Data cable that
connects to a NMEA 0183 interface. The end with three wires (red,
black and shield) is a power cable that connects to a NMEA-2000 buss.
The thicker three-wire cable (red, black and white) is the Power Supply
for your unit (and optional external speaker connection for some units).

The Power/Data cable for this unit.
Depending on your configuration, you may not use all of these wires.
(For example, many units cannot operate an optional external speaker,
so the white wire on the Power Supply cable isn't functional.) The following segments include instructions for installing all the wires that
you will use with this unit.
Powering a NMEA-2000 Buss
(NMEA-2000 Power cable)
A NMEA-2000 buss must be connected to a power source to operate. If
you have a pre-existing NMEA-2000 installation, it may already be
connected to another power source. If your NMEA-2000 buss is already
powered, you can ignore the NMEA-2000 Power cable. Never attach
two power sources to a single NMEA-2000 buss.
If you do need to power your NMEA-2000 buss, attach the NMEA-2000
Power cable to your boat's battery just as indicated in the following
segment for connecting your unit's Power Supply cable. The NMEA2000 Power cable's red wire should be attached (with provided 3-amp
fuse) to the boat battery's positive terminal, and the NMEA-2000 Power
cable's black and shield wires should both be attached to the battery's
negative terminal.
NOTE:
If the NMEA-2000 buss draws power directly from the boat's battery,
the LGC-2000 will remain on (drawing power) all the time. The LGC2000's current draw is very small and shouldn't decrease the boat's
storage battery life, but if this small draw is a concern, you can install a switch between the NMEA-2000 buss and the battery.
Powering Your Unit
(Power Supply cable – red and black wires)
The unit works from a 12-volt battery system. For the best results, attach the power cable directly to the battery. You can attach the power
cable to an accessory or power buss, however you may have problems
with electrical interference. Therefore, it's safer to go ahead and attach
the power cable directly to the battery.
13
CAUTION:
When using the unit in a saltwater environment, we strongly recommend that you shut off the power supply to the power cable when
the unit is not in use. When the unit is turned off but still connected
to a power supply, electrolysis can occur in the power cable plug.
This may result in corrosion of the plug body along with the electrical contacts in the cable and the unit's power socket.
In saltwater environments we recommend you connect the power
cable to the auxiliary power switch included in most boat designs.
If that results in electrical interference, or if such a switch is not
available, we recommend connecting direct to the battery and installing an inline switch. This will let you shut off power to the
power cable when the unit is not in use. When you are not using
the unit, you should always shut off power to the power cable, especially when the power cable is disconnected from the unit.
If possible, keep the power cable away from other boat wiring, especially
the engine's wires. This will provide the best isolation from electrical
noise. If the cable is not long enough, splice #18 gauge wire onto it. The
power cable has two wires, red and black. Red is the positive lead, black
is negative or ground. (There is also a white wire to power an optional
external speaker for some units.) Make sure to attach the in-line fuse
holder to the red lead as close to the power source as possible.
For example, if you have to extend the power cable to the battery or
power buss, attach one end of the fuse holder directly to the battery or
power buss. This will protect both the unit and the power cable in the
event of a short. It uses a 3-amp fuse.

NOTE:
If you're powering a NMEA-2000 buss, you will attach both the
NMEA-2000 Power cable and the unit's Power Supply cable to the
boat's battery. To attach the NMEA-2000 Power cable, connect the
red wire to battery's + and black and shield wires to battery's –.
WARNING:
This product must be independently fused with the enclosed 3-amp fuse (or equivalent), even if you connect to
a fused accessory or power buss.
If a malfunction happens inside the unit, extensive damage can occur if the enclosed fuse is not used. As with all
electrical devices, this unit could be damaged to a point
that it is unrepairable and could even cause harm to the
user when not properly fused.
CAUTION:
Do not use this product without a 3-amp fuse wired into the power
cable! Failure to use a 3-amp fuse will void your warranty.
This unit has reverse polarity protection. No damage will occur if the
power wires are reversed. However, the unit will not work until the
wires are attached correctly.
An optional 8-foot, CA-4 external power cable with a cigarette lighter
adapter is available from Lowrance.
NMEA 0183/DGPS Cable Connections
NMEA is a standard communications format for marine electronic
equipment. For example, an autopilot can connect to the NMEA interface on the GlobalMap 4800M and receive positioning information. The
GlobalMap 4800M can exchange information with any device that
transmits or receives NMEA 0183 data.
DGPS is an acronym for the Differential Global Positioning System.
DGPS supplements and boosts the accuracy of basic GPS. DGPS was
developed by the U.S. Coast Guard, which is responsible for the system's operation in the United States. Since it's creation, DGPS has become the international maritime standard for marine navigation.
The most popular DGPS system relies on a grid of ground-based transmitters that send correction signals to DGPS receivers. These in turn,
connect to the GPS receiver (such as the GlobalMap 4800M). Lowrance
offers an optional DGPS receiver for your unit.
15
See the following diagram for general wiring connections. Read your
other product’s owner’s manual for more wiring information.
NMEA/DGPS Wiring
(Data cable)
To exchange NMEA 0183 or DGPS data, the GlobalMap 4800M has one
NMEA 0183 version 2.0 communication port. Com port one (Com-1) can
be used to receive NMEA format GPS data or DGPS data. The com port
can also transmit NMEA format GPS data to another device.
The four wires for the com port are combined with the Power Supply
cable and NMEA-2000 Power cable to form the power/data cable
(shown earlier). Com-1 uses the yellow wire to transmit, the orange
wire to receive and the shield wire for signal ground. Your unit does not
use the blue wire.

Mounting the Unit: Bracket, In-Dash or Portable
You can install the GlobalMap 4800 on the top of a dash with the supplied gimbal bracket. It can also be installed in the dash or mounted on
a portable power supply.
16
If you use the supplied bracket, you may be interested in the optional
R-A-M
bracket mounting system. This converts the unit's gimbal
bracket to a swivel mount, which can be used on the dash or overhead
mounting positions.
Optional R-A-M mounting system.
Bracket Installation
Mount the GlobalMap 4800 in any convenient location, provided there is
clearance behind the unit when it's tilted for the best viewing angle. You
should also make sure there is enough room behind the GlobalMap 4800 to
attach the power and GPS antenna/receiver module cables. (A drawing on
the next page shows the dimensions of a gimbal-mounted GlobalMap 4800.)
Holes in the bracket's base allow wood screw or through-bolt mounting.
You may need to place a piece of plywood on the back side of thin fiberglass panels to reinforce the panel and secure the mounting hardware.
Front
Install the gimbal bracket. Orient the bracket so the arms slope toward
the front of your unit.
17
Drill a 1-inch (25.4 mm) hole in the dash for the power and antenna
cables. The best location for this hole is immediately under the gimbal
bracket location. This way, the bracket can be installed so that it covers
the hole, holds the cables in position and results in a neat installation.
Some customers, however, prefer to mount the bracket to the side of the
cable hole — it's a matter of personal preference.

After drilling the hole, pass the antenna connector up through the hole
from under the dash. Pass the power cable's bare-wire end down
though the hole from the top.
If you wish, you can fill in the hole around the cables with a good marine
caulking compound. (Some marine dealers stock cable hole covers to conceal the opening.) No matter what type of installation you prefer, be sure
to leave enough slack in the cables to allow tilting or swiveling the
GlobalMap 4800. If you choose to fill in the hole, be sure to position the
cables against the rear edge of the hole as you apply the fill material.
Before positioning the bracket, be sure to hold the cables against the
rear edge of the hole. Then, slide the bracket over the hole and butt the
rear of the bracket base firmly against the cables, thus pinning them in
place against the side of the hole. Finally, fasten the bracket to the
dash. Attach the unit to the gimbal bracket using the supplied gimbal
knobs and washers.
18
In-Dash Installation
You can mount the GlobalMap 4800 in the dash with an optional FM-5
In-Dash Adapter Kit. The kit includes mounting hardware, a template
for cutting the hole and an instruction sheet, part 988-0147-43.

Portable Installation
Like many Lowrance products, the GlobalMap 4800 is capable of portable operation by using the optional PPP-11 portable power pack. The
power pack and the magnet-equipped antenna module expand the uses
for your GPS unit. The PPP-11 makes it easy to transfer your unit from
a boat to a car, recreational vehicle, airplane or other vehicle without
drilling and mounting a second bracket. You can use your unit in your
own car or boat, then take it along when riding in a friend's vehicle
that's not equipped with GPS.
The PPP-11 Portable Power Pack can be used with eight "D" cell alkaline batteries or an optional sealed, rechargeable battery. For set-up
directions, refer to the pack's instruction sheet, part 988-0147-46.

MMC or SD Card Memory Card Installation
Your GlobalMap 4800 uses a MultiMedia Card to store information,
such as custom maps, waypoints, trails and other GPS data. The unit
can also use Secure Digital Cards (SD card) to store data.
NOTE:
Throughout this manual, we will use the term MMC, but just remember that your unit can use an MMC or SD card to store data.
Both of these solid-state flash memory devices are about the size of a
postage stamp. An SD card is slightly thicker than an MMC. As this
manual went to press, MMCs were available in storage capacities of 8
MB, 16 MB, 32 MB, 64 MB and 128 MB. SD cards were available in
capacities of 8 MB, 16 MB, 32 MB, 64 MB, 128 MB, 256 MB and higher.
Additional MMC cards are available from LEI Extras; see ordering information inside the back cover of this manual. MMCs and SD cards
are also available at many camera and consumer electronics stores.
The MMC slot is located in a compartment on the front of the case. The
compartment door is located at the lower right corner. The following
figure shows a close-up with the door opened.

Now that you have your GlobalMap 4800 installed, move on to Section
3, Basic GPS Operations. There, we'll present a series of step-by-step
tutorials to teach you the basics of GPS navigation.
Face Cover
Your unit comes with a white protective cover that snaps on and off the
front of the unit. This cover is intended for use when your unit and the
vehicle it's mounted in are idle.
WARNING:
When the unit is mounted in an unprotected area, such
as an open boat cockpit, the protective face cover must
be removed when the vehicle is moving at high speed.
This includes towing a boat on a trailer at highway
speeds. Otherwise, wind blast can pop off the cover.
