Introduction
Congratulations on your purchase of the Magellan GPS 315/GPS 320
receiver. Since introducing the world’s first commercial, hand-held GPS
receiver in 1989, Magellan has led the way with innovative GPS
products to meet a wide range of positioning and navigation needs.
The receiver is designed to get you out into the “Great Outdoors”
rather than spending hours reading the user’s manual. In order to get
you outdoors quickly, the manual is designed with key sequences rather
than wordy sentences.
Before you begin, make sure that your package includes the items listed
on the box. If any of these items are missing, please contact your local
Magellan dealer or distributor.
Conventions Used in this Manual
The manual is divided into chapters: Introduction, Getting Started, Basic
Operation, Reference, Customizing, Troubleshooting and Glossary. There
are also subchapters that describe NMEA, Datums and Accessories.
It is very important that you read through the Getting Started chapter
first as it prepares your receiver for use and provides basic instruction.
The Basic Operation chapter describes the features found in your
receiver including step-by-step instructions on their use.
The Reference section contains information to help you navigate using
waypoints, routes and auxiliary functions. Following is the Customizing
chapter, that allows you to establish options you want set in the receiver.
The Troubleshooting chapter gives you a problem and answer series to
guide you. The final chapter, Glossary, defines terms that may be
unfamiliar to you.
The manual is to be used with either the GPS 315 or the GPS 320.
These differ in that the GPS 315 has a database of worldwide cities
consisting of major, large and medium cities. The GPS 320 has a
database of worldwide cities as well as lighthouses, fixed navaids, buoys,
large and medium cities for three different regions of the world (North/
Central/South America, Europe/Africa and Australia/Asia).

Primary Usage
Getting a Fixed Position
Receiver Accuracy
The satellite constellation that provides the GPS information used by
the receiver is maintained by the Department of Defense (DoD). GPS
positioning, for general use, provides 25 meter RMS accuracy or better.
Since the signals generated by these satellites are publicly accessible, the
DoD has introduced errors in the satellite signals for security reasons.
These errors are referred to as Selective Availability (SA).
At present, your GPS position will be accurate within 100 meters
horizontally and 150 meters vertically. Due to these errors introduced
by SA, it is possible to get readings outside of these values at times.
Installing the Batteries
The receiver uses two AA batteries that are installed at the back. To
remove the battery cover, turn the ring of the battery door screw
counter-clockwise until the battery
cover can be removed.
Insert the new batteries as shown, being
sure to respect the polarities, and replace
+
-
the cover.
-
+
Replace the screw and turn the ring
clockwise until the battery door is held
in place securely. Avoid overtightening
the battery door screw.
Once the batteries have been removed,
the receiver loses time and date after 20 minutes.

Proper Handling - Signal Reception
Clear View of the Sky. Because the receiver attains information it needs
from satellites orbiting the earth, the antenna needs to have a relatively
unobstructed view of the sky. This allows the receiver to choose from
all satellites currently available.
If the view of the sky is poor, (large cliffs or buildings, heavy foliage or
other obstructions) the satellite signals can be blocked and the receiver
may take longer to compute a position fix.
Holding the Receiver. The receiver is designed to fit comfortably in
your hand. Hold the receiver in the palm of your hand with the antenna
pointing towards the sky.
Power On
PWR
If after powering the receiver on, you do not press ENTER within 10
seconds, the receiver will shut off automatically.
Initialize
You do not need to initialize your receiver each time you use it unless the
memory has been cleared or if it has been transported more than 300 miles
while turned off.
Initialize for First Time Use
If the Initialize screen does not appear, then the receiver has already
been initialized. The other steps in this procedure are not required.

Getting a Fixed Position
Now you should go outside in an area where you can get a clear view of
the sky. The receiver will begin acquiring data from the satellites in
view and will display the progress on the STATUS screen. Once the
receiver has computed a fixed position, the POSITION screen will be
displayed.
Saving Your Waypoint
Once the receiver has computed your current position, you may save

You have completed the basic operation for
your receiver. From the information pro-

place quickly and easily.
The following chapters provide you with
additional information on using your receiver
that build on what you have learned.

Reference
The Reference section contains information that will help
you navigate using your receiver. Now that you have read
the Basic Operation section, you have reviewed the basic
usage. The Reference section will cover waypoints, routes,
and auxiliary functions.
The Working with Waypoints section tells you how to
create, edit, delete, project and sort waypoints. These
functions will guide you in the uses of waypoints. You can
create your own waypoints (known as User waypoints) or
use the waypoints already in the receiver’s memory (Non-
User waypoints). You can store up to 500 user positions
which can be used to build routes for navigation.
As stated earlier in the user manual, the GPS 315 has a
database of worldwide cities and the GPS 320 has a
database of cities and marine navaids for three different
regions of the world: North/Central/South America,
Europe/Africa and Australia/Asia.
The Working with Routes section tells you of the four
different types of routes consisting of GOTO, BACK-
TRACK, MOB and MULTI-LEG ROUTE. A route is a
planned course of travel defined by a series of waypoints
saved in the receiver’s memory. The receiver holds 20
routes with 30 legs. The route function allows you to
create, activate/deactivate, view/edit or delete any one of
the 20 routes.
The Auxiliary Function section tells you how to select the
Sun/Moon and Fish/Hunt options, contrast, simulate
mode and the alarms and message functions. You can
choose from the Anchor alarm, Arrival alarm, XTE alarm,
Proximity alarm and GPS Fix alarm. These alarms can be
reset to the alarm default settings or can be cleared of
defaults.
Following, you will find the Customizing section. Cus-
tomizing allows you to use the Setup menu to establish
the options you would like to set in your receiver.

Working with Waypoints
This section tells you how to edit, delete, project and sort
waypoints. You can store up to 500 user positions which
can be used to build routes for navigation.
Waypoints consist of two types, User and Non-User. The
User types are made up of waypoints that you can save in
the receiver’s memory. You can edit and delete these
waypoints, if you wish. The Non-User types display
locations, their coordinates and a description. These are
permanently stored in the receiver’s memory and cannot be
deleted unless written over by waypoints downloaded from
the DataSend™ CD.
You can store up to
10 Non-User
waypoint categories.
To help you understand the difference, the chart below
shows the functions of the User and Non-User waypoints.

DataSend™ CD (optional)
DataSend™ software contains a database of waypoints that
can be sent to your receiver and are broken down into
multiple categories. The software allows you to select a
geographical area and enable waypoint categories for that
location to be transferred into the receiver.
Using DataSend™
After you have installed DataSend™ you are ready to view
and send waypoints to the receiver. While running
DataSend™ you will see a background map of the world
that you can zoom in to see enabled waypoints.
If you want to send waypoints to your receiver, you must
select the geographic area first, then from the waypoint list
you can make your selection of waypoints to send. The
software will compute the amount of memory required and
whether your selection fits into your receiver. If it exceeds
the available receiver memory, either the geographic area, list
of waypoints selected, or both, can be decreased and the
memory requirements recomputed. The list of waypoints
selected in the specified geographic area can then be saved
under a project name you enter.
Don’t worry about
losing the
waypoints that
came with the
receiver, they are
available on the
CD for retrans-
mission to the
receiver.
You can then send the waypoints to the receiver which
replace all waypoints in the receiver. The default waypoints
that came with the receiver can be restored at any time.

Working with TrackRoute
TrackRoute (previously called Map ‘N Track in the receiver)
consists of track points collected by the Track History
function. A track can be up to 1200 points in size.
Activating. By activating the TrackRoute at the top of the
ROUTE MENU, you can navigate from the first created
track point to the last track point, making a reverse BACK-
TRACK. This turns the Track History logging off to keep
from overwriting track points in memory. The top of the
navigation screens will indicate TO: LEGXXXX where
XXXX is between 0 to 1200. As you navigate with the
receiver and pass individual track points, the legs will switch
and countdown until you reach LEG 0 which is your final
destination.
Deactivate. When TrackRoute is deactivated, Track History
logging begins. The track points will be overwritten once
the receiver records new position fixes.
Reverse. This reverses the TrackRoute or the track in Track
History.
Delete. This erases the track points in Track History.
Backtrack. This activates BACKTRACK Route by saving
the Track History as a 30 leg route and activating it.
There may be
some track
points that are
close to each
other causing
the receiver to
skip 1 or more
of these legs.

simulate navigation using that route. AUTO mode uses a
speed of 25 mph and automatically generates a COG to
follow the route. USER mode allows you to set the speed
and COG to values you enter.
CONTRAST
If your receiver is not computing a position fix
after exiting Simulate mode, you may need to
reset your present position by reinitializing.
This is due to the Simulated position being
more than 300 miles from your actual present
position.

Pin 5: Sig. GND
To use the PC interface cable to interface the GPS receiver with the DBR-2 or
DBR-3, you must use a null modem (Radio Shack P/N: 26-264A) and a gender
changer (Radio Shack P/N: 26-280A) to connect the GPS receiver properly. This
is due to the pinout being the opposite of the DB9 connector configuration for a
PC connection.

Troubleshooting
Receiver will not turn on:
1. Check to see if batteries are installed correctly.
2. Replace with two new AA alkaline or lithium batteries.
Takes more than 10 minutes to get a position fix:
1. If there are any obstacles nearby or overhead, move to a new
location.
2. Make sure that the antenna is pointing up, has a clear view of the
sky and is a reasonable distance away from your body.
3. Check Satellite Status to see where the satellites are and if the
receiver is acquiring data.
4. If the receiver still does not get a position fix within 10 minutes,
you may wish to repeat the initialization procedure.
Elevation jumps up and down:
1. Errors induced by the Department of Defense called Selective
Availability (SA) can cause the elevation values to fluctuate.
Battery life seems shorter than it should be:
1. Make sure that you are using two AA alkaline or lithium
batteries.
2. Shorter life span of the batteries can be due to excessive use of
the backlight. Turn the backlight off when not needed.
Position coordinates on your receiver do not match the location on
your map.
1. Make sure that your receiver is set up to use the same datum as
your map. The map datum is generally shown in the map
legend. See Map Datum under Reference for instructions on
selecting the map datum in your receiver.
2. Check your LAT/LON format. Make sure that the format
selected in COORDINATE SYSTEM (DEG/MIN/SEC or
DEG/MIN.MM) is in the same format as the map you are
using.

Commonly Asked Questions
Does the receiver adjust itself for daylight savings time?
No. You need to reset the time for changes in your area (see
Selecting Time Format).
Will my receiver function correctly in the year 2000?
Yes. Even though the last two digits of the year are displayed, the
full year designator is stored in memory.
Why won’t the receiver accept the coordinates I am inputting?
The most common cause is that you are trying to enter coordi-
nates that are in degrees/minutes while your receiver is set to
degrees/minutes/seconds. Because the last two digits in degrees/
minutes are in hundredths (00-99) and degrees/minutes/seconds
can be no higher than 59 (00-59), inputting a number higher
than 59 while in deg/min/sec results in an error and the receiver
does not accept the entry.
Can I use NiCad batteries in my receiver?
Yes. However, the battery life of your receiver will be diminished
as well as the possibility of an incorrect reading on the battery
life gauge with the use of NiCad batteries.
You say my receiver should work up to 15 hours on two batteries, but
mine doesn’t last that long?
There can be two reasons. The first, and most common, reason
is that you have the display backlight on. The light increases the
drain on the batteries causing the decrease in battery life. The
second reason is that you are using NiCad batteries. As men-
tioned, while your receiver will operate on NiCad batteries, the
battery life is diminished.
Why is the time and date incorrect after I replace the batteries?
If the batteries are removed for 20 minutes or more, the receiver
will lose the time and date. The receiver will collect time and
date soon after tracking a satellite.

NMEA DATA MESSAGES
Your GPS receiver can be set to output GPS data in the NMEA 0183 version
1.5 or version 2.1 format to interface with other marine devices or equipment.
NMEA DATA MESSAGES. NMEA data is output at 4800 baud, 8, N, 1,
checksum off. These settings are acceptable to most equipment and software
applications. The baud rate can also be set to 1200, 9600 or 19200.
There are several NMEA output message sets, each with a slightly different
application. Check documentation for your external equipment to choose
the appropriate message set.

Glossary
Active Leg
Altitude
BRG
The segment of a route currently being traveled.
The current elevation above sea level.
Bearing. The compass direction from your position
to a destination, measured to the nearest degree.
Buoy
A navigation aid (usually found in marine charts) that
is floating in water. The position can vary due
to the magnitude and direction of the current.
COG
Course Over Ground. The direction the receiver is
moving. COG can be reported in true or magnetic
north values.
Coordinates
CTS
A unique numeric or alphanumeric description of the
position.
Course to Steer. The direction you should be traveling
in order to return to the course while proceeding
towards the destination. It is a “compromise” course
bearing that projects from your current position to a
point on the courseline mid-way between a point
perpendicular to your position and the current leg
destination waypoint.
Datum
Refers to the theoretical mathematical model of the
earth’s sea level surface. Map makers may use a
different model to chart their maps, so position
coordinates will differ from one datum to another. The
datum for the map you are using can be found in the
legend of the map. If you are unsure of which datum
to use, use WGS84.
Default
DST
The value or setting automatically chosen by the unit
unless otherwise directed. Can be changed in Setup.
Distance. Distance from position to destination.

Ephemeris
The position and velocity of the satellites in the
sky. The receiver uses the ephemeris to calculate the
precise distance from the GPS receiver to the satellite.
ETA
ETE
Estimated Time of Arrival. The estimated time of day
the leg’s destination waypoint will be reached.
Estimated Time Enroute. The estimated time
remaining to reach the next waypoint in a route.
Fixed Navaid A navigation aid (usually found in marine charts) that
has a fixed position and can be found on land or water.
An example is a T.V. tower on land or a Greenday mark
in water.
HDG
Heading. The direction you are facing, defined as an
angle from North.
Latitude
The angular distance north or south of the equator
measured by lines encircling the earth parallel to the
equator from 0˚ to 90˚.
LAT/LON
Leg (Route)
Coordinate system using latitude and longitude
coordinates to define a position on the earth.
A segment of a route that has a starting (FROM)
waypoint and a destination (TO) waypoint. A route
may consist of 1 or more legs. A route that is from
waypoint A to waypoint B to waypoint C to waypoint
D has three legs with the first being from waypoint A to
waypoint B.

LMK
Landmark. A location saved in the unit’s
memory which is obtained by entering data,
editing data, calculating data or saving a
current position. Used to create routes. Same
as a waypoint.
Longitude
The angular distance east or west of the prime
meridian (Greenwich Meridian) as measured
by lines perpendicular to the parallels and
converging at the poles from 0˚to 180˚.
Magnetic North
NMEA
The direction relative to a magnetic compass
National Marine Electronics Association. A
professional organization that defines and
maintains the standard serial format used by
marine electronic navigation equipment and
computer interfaces.
OSGB
A coordinate system describing only Great
Britain, similar to UTMs. Used with GRB36
datum.
Position fix
SOG
Position coordinates as computed by the GPS
receiver.
Speed Over Ground. The speed at which the
receiver is moving.
TRN
Turn. Degrees or direction to turn.
True North
The direction to North Pole from an
observer’s position. The north direction on
any geographical meridian.
TTG
Time To Go. The measurement of how long
it will take you to arrive at your destination.
TTG is based on how fast you are moving
towards the destination and the distance
remaining.

UTC
Universal Time Coordinated. Formerly
referred to as Greenwich Mean Time (GMT).
UTM
Universal Transverse Mercator metric grid
system used on most large and intermediate
scale land topographic charts and maps.
VMG
Velocity Made Good. The component of the
velocity that is in the direction of the destina-
tion.
Waypoint
WPT. A location saved in the receiver’s
memory which is obtained by entering data,
editing data, calculating data or saving a
current position. Used to create routes.
XTE
