Introduction
This manual explains the operation of the Navigation System. Please read this manual
carefully to ensure proper use. Keep this manual in your vehicle at all times.
The screen shots in this document and the actual screens of the navigation system dif-
fer depending on whether the functions and/or a contract existed and the map data
available at the time of producing this document.
Please be aware that the content of this manual may be different from the navigation
system in some cases, such as when the system’s software is updated.
The Navigation System is one of the most technologically advanced vehicle accesso-
ries ever developed. The system receives satellite signals from the Global Positioning
System (GPS) operated by the U.S. Department of Defense. Using these signals and
other vehicle sensors, the system indicates your present position and assists in locating
a desired destination.
The navigation system is designed to select efficient routes from your present starting
location to your destination. The system is also designed to direct you to a destination
that is unfamiliar to you in an efficient manner. The system uses DENSO maps. The cal-
culated routes may not be the shortest nor the least traffic congested. Your own per-
sonal local knowledge or “short cut” may at times be faster than the calculated routes.
The navigation system’s database includes Point of Interest categories to allow you to
easily select destinations such as restaurants and hotels. If a destination is not in the da-
tabase, you can enter the street address or a major intersection close to it and the sys-
tem will guide you there.
The system will provide both a visual map and audio instructions. The audio instructions
will announce the distance remaining and the direction to turn in when approaching an
intersection. These voice instructions will help you keep your eyes on the road and are
timed to provide enough time to allow you to maneuver, change lanes or slow down.
Please be aware that all current vehicle navigation systems have certain limitations that
may affect their ability to perform properly. The accuracy of the vehicle’s position de-
pends on satellite conditions, road configuration, vehicle condition or other circum-
stances. For more information on the limitations of the system, refer to page 160.

zAccurate current position may not be
shown in the following cases:
• When driving on a small angled Y-shaped
road.
• When driving on a winding road.
• When driving on a slippery road such as in sand, gravel, snow, etc.
• When driving on a long straight road.
• When freeway and surface streets run in parallel.
• After moving by ferry or vehicle carrier.
• When a long route is searched during high speed driving.
• When driving without setting the current position calibration correctly.
• After repeating a change of direction by going forward and backward, or turning
on a turntable in a parking lot.
• When leaving a covered parking lot or parking garage.
• When a roof carrier is installed.
• When driving with tire chains installed.
• When the tires are worn.
• After replacing a tire or tires.
• When using tires that are smaller or larger than the factory specifications.
• When the tire pressure in any of the 4 tires is not correct. z
Inappropriate route guidance may occur in
the following cases:
• When turning at an intersection off the
designated route guidance.
• If you set more than 1 destination but skip any of them, auto reroute will display a
route returning to the destination on the
previous route.
• When turning at an intersection for which there is no route guidance.
• When passing through an intersection for which there is no route guidance.
• During auto reroute, the route guidance may not be available for the next turn to
the right or left.
• During high speed driving, it may take a long time for auto reroute to operate. In
auto reroute, a detour route may be
shown.
• After auto reroute, the route may not be changed.
• If an unnecessary U-turn is shown or announced.
• If a location has multiple names and the system announces 1 or more of them.
• When a route cannot be searched.
• If the route to your destination includes gravel, unpaved roads or alleys, the route
guidance may not be shown.
• Your destination point might be shown on the opposite side of the street.
• When a portion of the route has regula- tions prohibiting the entry of the vehicle
that vary by time, season or other reasons.
• The road and map data stored in the navi- gation system may not be complete or
may not be the latest version.
z If the vehicle cannot receive GPS signals,
the current position can be adjusted
manually. For information on setting the
current position calibration: →P. 1 5 5

2. RADIO OPERATION
IS250/350_Navi_U
AUTOMATIC PLAYBACK OF
THE CACHE
If the radio broadcast is interrupted by
another audio output, such as an
incoming phone call, the system will
automatically cache the interrupted
portion and perform time-shift playback
when the interruption ends. To manually
operate the cache operation: ( →P. 185)
INFORMATION
●The system can store up to 15 minutes.
Cached data will be erased when the
radio mode or station is changed or when
the audio system is turned off.
● If noise or silence occurs during the cach-
ing process, cache writing will continue,
with the noise or silence recorded as is. In
this case, the cached broadcast will con-
tain the noise or silence when played
back.
RADIO BROADCAST DATA
SYSTEM
This audio system is equipped with Ra-
dio Broadcast Data Systems (RBDS).
RBDS mode allows text messages to be
received from radio stations that utilize
RBDS transmitters.
When RBDS is on, the radio can
— only select stations of a particular pro-
gram type,
— display messages from radio stations,
— search for a stronger signal station.
RBDS features are available only when
listening to an FM station that
broadcasts RBDS information and the
“FM Info” indicator is on.
