Radio Reception
Frequency interference and static can occur during
normal radio reception if items such as cell phone
chargers, vehicle convenience accessories, and external
electronic devices are plugged into the accessory
power outlet. If there is interference or static, unplug
the item from the accessory power outlet.
AM
The range for most AM stations is greater than for
FM, especially at night. The longer range can cause
station frequencies to interfere with each other.
For better radio reception, most AM radio stations
boost the power levels during the day, and then reduce
these levels during the night. Static can also occur
when things like storms and power lines interfere with
radio reception. When this happens, try reducing
the treble on the radio.
FM Stereo
FM signals only reach about 10 to 40 miles
(16 to 65 km). Although the radio has a built-in electronic
circuit that automatically works to reduce interference,
some static can occur, especially around tall buildings or
hills, causing the sound to fade in and out.
XM Satellite Radio Service
XM Satellite Radio Service gives digital radio reception
from coast-to-coast in the 48 contiguous United States,
and in Canada. Just as with FM, tall buildings or
hills can interfere with satellite radio signals, causing
the sound to fade in and out. In addition, traveling
or standing under heavy foliage, bridges, garages, or
tunnels may cause loss of the XM signal for a period
of time.
Cellular Phone Usage
Cellular phone usage may cause interference with the
vehicle’s radio. This interference may occur when
making or receiving phone calls, charging the phone’s
battery, or simply having the phone on. This interference
causes an increased level of static while listening to
the radio. If static is received while listening to the radio,
unplug the cellular phone and turn it off.

Section 4 Navigation System
4-1

Global Positioning System (GPS)
The navigation system determines the position of the
vehicle by using satellite signals, various vehicle signals,
and map data.
At times, other interferences such as the satellite
condition, road con guration, the condition of the vehicle
and/or other circumstances can interfere with the
navigation system’s ability to determine the accurate
position of the vehicle.
The GPS shows the current position of the vehicle using
signals sent by the GPS Satellites of the United States
Department of Defense. When the vehicle is not
receiving signals from the satellites, a symbol appears
on the map screen. Refer toSymbols on page 4-43.This system may not be available or interferences may
occur if any of the following is true:Signals are obstructed by tall buildings, trees, large
trucks, or a tunnel.
Objects are located on the rear shelf of the vehicle.
Satellites are being repaired or improved.
After-market glass tinting has been applied to the
vehicle’s rear windshield.
Notice:Do not apply after-market glass tinting to
the vehicle’s windows. Glass tinting interferes
with the system’s ability to receive GPS signals and
causes the system to malfunction. The window
might have to be replaced to correct the problem.
This would not be covered by the warranty.
For more information if the GPS is not functioning
properly, seeIf the System Needs Service on page 4-51
andProblems with Route Guidance on page 4-51.

Problems with Route Guidance
Inappropriate route guidance may occur under one or
more of the following conditions:
You have not turned onto the road indicated.
Route guidance may not be available when using
automatic rerouting for the next right or left turn.
The route may not be changed when using
automatic rerouting.
There is no route guidance when turning at an
intersection.
Plural names of places may be announced
occasionally.
It may take a long time to operate automatic
rerouting during high-speed driving.
Automatic rerouting may display a route returning to
the set waypoint if you are heading for a destination
without passing through a set waypoint.
The route prohibits the entry of a vehicle due to a
regulation by time or season or any other regulation
which may be given.
Some routes may not be searched.
The route to the destination may not be shown if
there are new roads, if roads have recently
changed, or if certain roads are not listed on the
map DVD. SeeOrdering Map DVDs on page 4-52.
To recalibrate the vehicle’s position on the map, see
“Adjust Vehicle Position” underSetup Menu on
page 4-12to calibrate the system.
If the System Needs Service
If the navigation system needs service and the steps
listed here have been followed but there are still
problems, see your dealer/retailer for assistance.

Radio Data Systems (RDS)
The audio system has a Radio Data System (RDS).
RDS features are available for use only on FM stations
that broadcast RDS information. With RDS, the radio can:
Seek to stations broadcasting the selected type of
programming
Receive announcements concerning local and
national emergencies
Display messages from radio stations
Seek to stations with traffic announcementsRDS:Touch RDS to use alternate RDS functions
located in the preset menu. After touching RDS, there
is about ve seconds to choose RDS ON/OFF, TA,
MSG, PTY, or SEL PTY. If no selection is made, the
system returns to the previous menu.
If tuned to a station broadcasting RDS information, the
station’s Program Service (PS) and Program Type (PTY)
will replace the station’s frequency on the status line
at the top of the display. After about ve seconds, if
available, the PTY will be replaced on the display by the
station’s PTY name. The PTY and PTY name may be the
same or different.
If the audio system is tuned to a station that is not
broadcasting RDS information, the station’s frequency
remains on the display. While RDS is on, the audio
system searches for a stronger station in the network
if a station gets too weak for listening.
The RDS feature relies upon receiving speci c
information from RDS stations. These features only
works when RDS information is available.
TA (Traffic):Touch TA to receive traffic announcements.
The audio system turns on the TA display. TA appears on
the display if the current station broadcasts traffic
announcements. Traffic announcements can also be
received from stations in the network related to the
