Playing Audio Through Your Vehicle Speakers
Playing Audio
Through Your Vehicle
Speakers
Check local laws before using the FM
transmitter in your area.
If an FM transmitter is available on your
nüvi, you can listen to the nüvi audio on
an FM stereo.
NOTE: When using the FM
transmitter function on the nüvi,
hands-free phone calls through the
nüvi might be overheard by adjacent
vehicles through the FM stereo.
1. From the Menu page, touch Volume
> Audio Output > FM Transmitter >
OK.
2. Tune your stereo to an FM channel
that has a lot of static and has a low
FM frequency number.
3. Touch the Current FM Frequency
button.
4. Touch and to select the same
frequency to which your stereo is
tuned.
Frequency Selection Tips
For best results, select a frequency below
90.1 FM.
When searching for an appropriate FM
frequency on your FM stereo, look for
an unused frequency that has steady,
consistent static. If you hear slight noises
and sounds in the background of the
static, select a different frequency.
As you travel, you might need to change
the frequency for the FM transmitter.
A frequency not used by a radio station
in your area might be used by a station
elsewhere.
FM Transmitter
Information
The FM transmitter is intended to
transmit the audio from the nüvi to your
FM stereo.
Do not adjust your FM settings while
you are driving your vehicle.
Page 38
32 nüvi 715 Series Owner’s Manual
Playing Audio Through Your Vehicle Speakers
The distance between the vehicle power
cable, the nüvi, and the FM stereo
antenna may also affect the noise level.
Vehicles with antennas located far
away, such as a rear-mounted antenna,
may experience more interference from
outside noise sources than vehicles with
front-mounted antennas.
As you drive, you may notice changes
in the background static even though
there is no FM station using that
channel. You may notice this as you
drive through intersections where certain
kinds of trafc lights or other municipal
electronic systems are operating. You
might also notice this effect when the
terrain changes, allowing distant stations
to be received by your car stereo that
were not received when you made your
initial frequency selection. These and
other sources of electrical interference
may make it necessary to look for
another frequency.

(Navigation Satellite Timing and Ranging)
Global Positioning System, originally was
developed for the military.
Because of its popular
navigation capabilities
and because you can
access GPS technology
using small, inexpensive
equipment, the government
made the system available
for civilian use. The USA
owns GPS technology and
the Department of Defense
maintains it.
GPS technology requires
the following three segments:

Space Segment
At least 24 GPS satellites orbit the earth
twice a day in a specic pattern. They travel
at approximately 7,000 miles per hour about
12,000 miles above the earth’s surface.
These satellites are spaced so that a GPS
receiver anywhere in the world can receive
signals from at least four of them.
Each GPS satellite constantly sends coded
radio signals (known as pseudorandom code)
to the earth. These GPS satellite signals
contain the following information:
The particular satellite that is sending the •
information
Where that satellite should be at any •
given time (the precise location of the
satellite is called ephemeris data)
Whether or not the satellite is working •
properly
The date and time that the satellite sent •
the signal
The signals can pass through clouds, glass,
and plastic. Most solid objects such as
buildings attenuate (decrease the power of)
the signals. The signals cannot pass through
objects that contain a lot of metal or objects
that contain water (such as underwater
locations).
The GPS satellites are powered by solar
energy. If solar energy is unavailable, for
example, when the satellite is in the earth’s
shadow, the satellites use backup batteries to
continue running. Each GPS satellite is built
to last about 10 years. The Department of
Defense monitors and replaces the satellites
to ensure that GPS technology continues to
run smoothly for years to come.
Control Segment
The control segment is responsible for
constantly monitoring satellite health, signal
integrity, and orbital conguration from the
ground. The control segment includes the
following sections:
Master control station•
Monitor stations•
Ground antennas•
Monitor Stations
At least six unmanned monitor stations
are located around the world. Each station
constantly monitors and receives information
from the GPS satellites and then sends the
orbital and clock information to the master
control station (MCS).

GPS Beginner’s Guide 51
Master Control Station (MCS)
The MCS) is located near Colorado Springs
in Colorado. The MCS constantly receives
GPS satellite orbital and clock information
from the monitor stations. The controllers
in the MCS make precise corrections to the
data as necessary, and send the information
(known as ephemeris data) to the GPS
satellites using the ground antennas.
The following points provide a summary of
the technology at work:
Ground Antennas
Ground antennas receive the corrected
orbital and clock information from the MCS,
and then send the corrected information to
the appropriate satellites.
User Segment
The GPS user segment consists of your
GPS receiver. Your receiver collects and
processes signals from the GPS satellites that
are in view and then uses that information to
determine and display your location, speed,
time, and so forth. Your GPS receiver does
not transmit any information back to the
satellites.
How Does GPS
Technology Work?
The control segment constantly monitors •
the GPS constellation and uploads
information to satellites to provide
maximum user accuracy.
Your GPS receiver collects information •
from the GPS satellites that are in view.
Your GPS receiver accounts for errors. •
For more information, refer to the
Sources of Errors (Page 55) section.
Your GPS receiver determines your •
current location, velocity, and time.
Your GPS receiver can calculate other •
information, such as bearing, track, trip
distance, distance to destination, sunrise
and sunset time, and so forth.
Your GPS receiver displays the •
applicable information on the screen.

Who Uses GPS?
GPS technology has many amazing
applications on land, at sea, and in the
air. You might be surprised to learn about
the following examples of how people
or professions are already using GPS
technology:
Environment
GPS technology helps survey disaster areas
and map the movement of environmental
phenomena (such as forest res, oil spills,
or hurricanes). It is even possible to nd
locations that have been submerged or
altered by natural disasters.
Agriculture
In precision farming, GPS technology helps
monitor the application of fertilizer and
pesticides. GPS technology also provides
location information that helps farmers
plow, harvest, map elds, and mark areas of
disease or weed infestation.
Aviation
Aircraft pilots use GPS technology for en
route navigation and airport approaches.
Satellite navigation provides accurate aircraft
location anywhere on or near the earth.
Ground Transportation
GPS technology helps with automatic vehicle
location and in-vehicle navigation systems.
Many navigation systems show the vehicle’s
location on an electronic street map,
allowing drivers to keep track of where they
are and to look up other destinations. Some
systems automatically create a route and give
turn-by-turn directions. GPS technology also
helps monitor and plan routes for delivery
vans and emergency vehicles.
Marine
GPS technology helps with marine
navigation, trafc routing, underwater
surveying, navigational hazard location, and
mapping. Commercial shing eets use it to
navigate to optimum shing locations and to
track sh migrations.
Page 59
GPS Beginner’s Guide 53
Military
Military aircraft, ships, submarines, tanks,
jeeps, and equipment use GPS technology for
many purposes including basic navigation,
target designation, close air support, weapon
technology, and rendezvous.
Space
GPS technology helps track and control
satellites in orbit. Future booster rockets
and reusable launch vehicles will launch,
orbit the earth, return, and land, all under
automatic control. Space shuttles also use
GPS navigation.
Public Safety
Emergency and other specialty eets use
satellite navigation for location and status
information.
Rail
Precise knowledge of train location is
essential to prevent collisions, maintain
smooth trafc ow, and minimize costly
delays. Digital maps and onboard inertial
units allow fully-automated train control.
Surveying
Surveyors use GPS technology for simple
tasks (such as dening property lines)
or for complex tasks (such as building
infrastructures in urban centers). Locating
a precise point of reference used to be very
time consuming. With GPS technology, two
people can survey dozens of control points in
an hour. Surveying and mapping roads and
rail systems can also be accomplished from
mobile platforms to save time and money.
Recreation
Outdoor and exercise enthusiasts use GPS
technology to stay apprised of location,
heading, bearing, speed, distance, and time.
In addition, they can accurately mark and
record any location and return to that precise
spot.
Timing
Delivering precise time to any user is one of
the most important functions of GPS
technology. This technology helps
synchronize clocks and events around the
world. Pager companies depend on GPS
satellites to synchronize the transmission of

receiver on the surface of the earth.
The signals are so accurate that time can be
gured to much less than a millionth of a
second, velocity can be gured to within a
fraction of a mile per hour, and location can
be gured to within a few metres.
WAAS/EGNOS
The Wide Area Augmentation System
(WAAS) is a system of satellites and ground
stations that provides even better position
accuracy than the already highly accurate
GPS. Europe’s version of this system is the
How Accurate Is GPS?
GPS technology depends on the accuracy of
signals that travel from GPS satellites to a
GPS receiver. You can increase accuracy by
ensuring that when you use (or at least when
you turn on) your GPS receiver, you are in
an area with few or no obstacles between
you and the wide open sky. When you rst
turn on your GPS receiver, stand in an open
area for a few moments to allow the unit to
get a good x on the satellites (especially
if you are heading into an obstructed area).
This gives you better accuracy for a longer
period of time (about 4-6 hours).
It takes between 65 and 85 milliseconds for a
signal to travel from a GPS satellite to a GPS
European Geostationary Navigation Overlay
Service (EGNOS).
The Federal Aviation Administration
(FAA) developed the WAAS program.
It makes more airspace usable to pilots,
provides more direct en route paths, and
provides new precision approach services
to runways, resulting in safety and capacity
improvements in all weather conditions at
all locations throughout the U.S. National
Airspace System (NAS).
Although it was designed for aviation users,
WAAS supports a wide variety of other uses,
for example, more precise marine navigation.
To take advantage of WAAS technology, you
must have a WAAS-capable GPS receiver
in an area where WAAS satellite coverage
Page 61
GPS Beginner’s Guide 55
is available such as North America. No
additional equipment or fees are required to
take advantage of WAAS.
Sources of Errors
Errors can affect the accuracy of the GPS
signal. Take your GPS receiver to an area
with a wide and unobstructed view of the sky
to reduce the possibility and impact of some
errors. Here are some of the most common
GPS errors.
Ionosphere and Troposphere •
Delays—the satellite signal slows down
as it passes through the atmosphere.
The system uses a built-in model that
calculates an average delay to partially
correct this type of error.
Orbital Errors• —this terminology refers
to inaccuracies of the satellite’s reported
location.
Receiver Clock Errors• —the GPS
receiver has a built-in clock that can have
small timing errors.
Number of Satellites Visible• —
obstructions can block signal reception,
causing position errors or no position
reading. The more satellites that your
GPS receiver can view, the better the x
is.
Satellite Geometry/Shading• —refers to
the relative position of the satellites at
any given time. Ideal satellite geometry
exists when the satellites are located at
wide angles relative to each other. Poor
geometry results when the satellites are
located in a line or in a tight grouping.
Signal Multipath• —the GPS signal
bounces off of objects, such as tall
buildings or large rock surfaces, before it
reaches the GPS receiver. This increases
the travel time of the signal and,
therefore, causes errors.
Buying a GPS Receiver
Deciding which GPS receiver to buy can be
overwhelming. Think about how you want
to use the unit, for example, traveling or
running. Keep the following considerations
in mind:
Product Level• —do you want the basics,
or do you want all of the bells and
whistles? You can nd a unit that ts
your needs and budget.
Power Source• —will you be using the
unit away from an auxiliary power
source? You might need to carry extra
batteries. With some units, you can use a
vehicle adapter or AC power source.
Page 62
Portability• —do you have a preference
between a portable or a built-in unit?
Some units mount directly in the
dashboard of your boat, car, or aircraft.
Mapping Capability• —do you want to
know the general direction or street-level
details of your chosen path? Map data
can include streets, restaurants, tourist
attractions, marine data, topography, and
so forth.
Mounts• —a mount for your GPS can
be useful to keep your hands free
while navigating your bike, boat, car,
or airplane. Many units come with a
mount, and several additional mounts are
available.
Ease of Use• —some receivers provide
a tutorial or an easy-to-use touchscreen
interface. Some even have turn-by-turn
voice instructions as you are navigating
your route.
Antenna Confi guration• —where are you
going to use the unit? With some units,
you use only the built-in antenna. With
other units, you can attach an external
antenna to give you better reception.
Price• —which units t your price range?
An inexpensive entry-level unit can be a
great way to enter the GPS world.
Software• —whether you want to save
Complementary
Navigation Aids
Remember, a GPS receiver is a complement
to navigation and should not be the only
navigational tool that you use. Using a
paper map, a simple compass, and having
knowledge of manual navigation is a good,
safe practice.
