10 You can change the orientation of the map
from northup to headingup by touching
the orientation symbol at the top left of the
screen.
Northup symbol
Regardless of the direction of vehicle travel,
North is always up.
Headingup symbol
The direction of vehicle travel is always up.
A red arrow indicates North.
Limitations of the navigation
system
This navigation system calculates the cur-
rent vehicle position using satellite sig-
nals, various vehicle signals, map data,
etc. However, the accurate position may
not be shown depending on the satellite
condition, road configuration, vehicle
condition or other circumstances.
The Global Positioning System (GPS) devel-
oped and operated by the U.S. Department of
Defense provides an accurate current vehicle
position using 3 to 4 satellites. The GPS sys-
tem has a certain level of inaccuracy. While
the navigation system will compensate for
this most of the time, occasional positioning
errors of up to 300 feet (100 m) can and
should be expected. Generally, position er-
rors will be corrected within a few seconds.
1U019a
When your vehicle is receiving signals from
the satellites, the “GPS” mark appears at the
top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle posi-
tion on the map display. Tunnels, tall build-
ings, trucks, or even the placement of objects
on the instrument panel may obstruct the
GPS signals.
The GPS satellites may not send signals due
to repairs or improvements being made to
them.
Even when the navigation system is receiving
clear GPS signals, the vehicle position may
not be shown accurately or inappropriate
route guidance may occur in some cases.

(d) Detour setting
While the route guidance is operating, you
can change the route to detour around a
section of the route where a delay is
caused by road repairs, an accident, etc.
1. Touch the
“Route” switch.
2U069a
2. Touch the “Detour” switch.
2U070c
3. Select the switch below to select the
desired detour distance.
“1 Mile (km)”, “3 Miles (km)” or “5 Miles
(km)”: Touch one of these switches to start
the detour process. After detouring, the sys-
tem returns to the original guidance route.
“Whole Route”: If you touch this switch, the
system will calculate an entire new route to
the destination.
2U119a
This picture shows an example of how the
system would guide you around a delay
caused by a traffic jam.
1This position indicates the location of a
traffic jam caused by road repairs or an
accident.
2This route indicates the detour sug-
gested by the system.
INFORMATION
When your vehicle is on a freeway, the
detour distance selections are 5, 15,
and 25 miles (km).
The system may not be able to calcu-
late a detour route depending on the
selected distance and surrounding
road conditions.

145 For example, nearby buildings and terrain
can interfere with FM reception. Power lines
or telephone wires can interfere with AM sig-
nals. And of course, radio signals have a lim-
ited range. The farther you are from a station,
the weaker its signal will be. In addition, re-
ception conditions change constantly as your
vehicle moves.
Here are some common reception problems
that probably do not indicate a problem with
your radio:
FM
Fading and drifting stations — Generally, the
effective range of FM is about 40 km (25
miles). Once outside this range, you may no-
tice fading and drifting, which increase with
the distance from the radio transmitter. They
are often accompanied by distortion.
Multi−path — FM signals are reflective, mak-
ing it possible for two signals to reach your an-
tenna at the same time. If this happens, the
signals will cancel each other out, causing a
momentary flutter or loss of reception.
Static and fluttering — These occur when sig-
nals are blocked by buildings, trees, or other
large objects. Increasing the bass level may
reduce static and fluttering.Station swapping — If the FM signal you are
listening to is interrupted or weakened, and
there is another strong station nearby on the
FM band, your radio may tune in the second
station until the original signal can be picked
up again.
AM
Fading — AM broadcasts are reflected by the
upper atmosphere — especially at night.
These reflected signals can interfere with
those received directly from the radio station,
causing the radio station to sound alternately
strong and weak.
Station interference — When a reflected sig-
nal and a signal received directly from a radio
station are very nearly the same frequency,
they can interfere with each other, making it
difficult to hear the broadcast.
Static — AM is easily affected by external
sources of electrical noise, such as high ten-
sion power lines, lightening, or electrical mo-
tors. This results in static.CARING FOR YOUR COMPACT DISC
PLAYER, DVD PLAYER AND DISCS
Your compact disc player is intended for
use with 12 cm (4.7 in.) discs only.
Extremely high temperatures can keep
your compact disc player and DVD player
from working. On hot days, use the air
conditioning to cool the vehicle interior be-
fore you use the players.
Bumpy roads or other vibrations may
make your compact disc player and DVD
player skip.
If moisture gets into your compact disc
player and DVD player, you may not play
even though they appear to be working.
Remove the disc from the player and wait
until it dries.
CAUTION
Compact disc players and DVD players
use an invisible laser beam which could
cause hazardous radiation exposure if
directed outside the unit. Be sure to op-
erate the players correctly.
