This chapter explains navigation function operations.
Basic Operation
Navigation
Functions
What is Navigation?
Navigation is a system that measures the
location of your car and guides you along the
route to the set destination. Your car's location
displayed on the map is measured with the
“GPS” and “Map matching” functions.
GPS(Global Positioning
System)
The system that uses GPS satellites to detect
the location is called “GPS”. The radio signals
from these GPS satellites are received and
the location of one's own car is measured to
within about 30 to 200 meters.
• Measuring your car's location takes about 2
minutes in a location with a good view. The
first time this product is used or it is used
after a long while, it takes about 5 minutes to
measure your car's location. •
The GPS satellites are managed by the
Department of Defense of the United States
of America, which sometimes deliberately
reduces the location precision. When that
happens, the location of your car may not be
displayed in the correct location.
Map Matching
“Map matching” is a function that compares
the route tracking data for your car with the
road configuration in the map data, estimates
the road you are driving on, and displays this
on the map.
CAUTION
• The map displayed for navigation and
the traffic rule information were prepared
based on various types of information
when the map data was prepared, so
they may differ from the actual roads
and traffic regulations. Always follow the
actual roads and obey the actual traffic
regulations.
GPS Antenna
GPS antenna
The location of your car is measured by
receiving weak radio signals from GPS
satellites with the “GPS antenna”.
ADVICE
If the radio signals from the GPS satellite
are blocked, the location of your car may
not be displayed in the correct location, so
observe the following rules.
• Do not paste a mirror type film or shade
film that contains carbon onto the
windshield.
• Do not place anything on or near the
GPS antenna.
• Do not use a mobile phone, PHS,
computer, etc. near the GPS antenna.

Map Data
The map data may contain wrong or missing
characters, incorrect locations etc.
Position Measurement
When Accurate Position
Measurement Is Not Possible
Radio signals from GPS satellites cannot be
received in locations such as in tunnels, indoor
parking garages, locations surrounded by high
buildings, mountains or trees, under freeways
and elevated train lines. In such cases, the
position measurement uses autonomous
navigation based on the gyro sensor and
speed sensor, so accurate measurement of
your car's location may become impossible.
Measurement Error
When radio signals cannot be received from
GPS satellites, measurement error occurs
easily and the location of your car may not be
displayed correctly.
If you keep on driving, when it becomes
possible to receive radio signals from GPS
satellites, the error in the current location will
be automatically corrected. Reasons Why the Location of Your
Car Is Not Displayed Correctly
•
When a freeway and general road are near
each other
• When driving roads laid out in a grid
• When driving on a mountain road with a
sharp slope
• When turning left or right after having driven
a long while on a straight road
• Immediately after the engine is switched ON
• When driving at slow speed, for example on
a congested road or in a parking lot (Because
some cars do not output a vehicle speed
signal when driving too slow)
• When traveling with chains on the tires
• When the vehicle was turned on a turntable
or the like
• When driving through a fork in the road with
a small angle between the two branches
• After the vehicle has been moved by ferry or
the like
• When driving in a multi-level parking garage
or on a spiral road
• When zig-zagging on a wide road
• When a tire has been replaced with the
emergency spare
• When driving on snow, sand, or other
slippery road
3D Position Measurement
When effective radio signals for which
positional precision can be expected can be
received from four or more GPS satellites, the
3D position of latitude, longitude, and altitude
can be calculated.
“GPS Information”(P141)
2D Position Measurement
When effective radio signals for which
positional precision can be expected can be
received from three or more GPS satellites
but not enough for 3D position measurement,
the altitude is assumed to have remained
the same since the last time it could be
measured and only the 2D of latitude and
longitude can be calculated. In this case, the
positional precision is less than for 3D position
measurement.
“GPS Information” (P141)
Non-measurable Position
When effective radio signals from GPS
satellites for which positional precision can be
expected can not be received, the position is
not measured.

Route Search Methods
• The route displayed in the route guidance
is a reference route to the destination. It
is not necessarily the shortest route. This
route guidance also does not take traffic
congestion information into account.
• Not all roads are used in route guidance.
• Routes using ferries are set to be less
recommended than normal roads. Therefore,
even when a ferry provides a quicker route
to the destination, a route not using the ferry
may be displayed.
• When a toll road interchange, parking area,
or service area is set as the destination or
as a waypoint, select from an establishment
search or from a freeway simplified map and
set without scrolling the map.
• Sometimes, the route is not the same as the
one prepared previously even though the
same locations were set as the destination
and waypoints.
• Sometimes routes are displayed that include
pedestrian ways, stairs, etc. that are not
passable by vehicle.
• If there is no road to the destination or only
narrow roads, a route may be displayed
that goes to some place apart from the
destination.
• Because searches are carried out passing
alongside establishments, depending on the
road configuration, roundabout routes may
be displayed.
• Sometimes routes are searched that take
traffic rule information into account.
• Sometimes, some temporary rules are not
taken into account or the time for which
they are applied differs from when they are
actually in effect.
Route Guidance
• When your car is driving on the searched
route, this displays the distance until the
destination or the next waypoint.
• When your car is driving off the searched
route, this displays the distance from the
point where you left the route until the
destination or the next waypoint.
• The display of the estimated time of arrival
at the destination is calculated based on the
remaining time data in the map data and
learning trip information.
• Sometimes even though you need to turn
at a junction, the junction name is not in the
guidance and the junction is not covered in
the audio guidance.
• Sometimes left and right turn guidance
differs from the actual road configuration.
• When you go off the route, for example by
turning one junction too early, sometimes the
audio guidance continues for the route you
had been on.
• Sometimes the distance in the guidance is
slightly too high or too low.
Precautions for operating the
navigation
• During route guidance, always obey the
actual traffic regulations. Failure to do so
may cause a traffic accident.
• The route is searched using the map data on
the map card. Sometimes it may differ from
actual restrictions for construction, one-way
rules, and other traffic rules. Always obey
the actual traffic regulations.
• Traffic rules that depend on the time of
day reflect the time at which the route was
searched. When driving the route, always
obey the actual traffic regulations.
• The distance your car has traveled is
measured with the speed sensor (and this
speed is proportional to the rotation rate of
the tires).When the tires are new, if you have
non-standard tires, or if the tire air pressure
is not correct, error inputs the distance
measurement more easily and the location
of your car may not be displayed correctly.
• The route is a reference route to around the
destination. It is not the shortest route or the
route most free of traffic congestion.
• While you are driving, the amount of road
information displayed is restricted and some
roads may not be displayed.(For example,
narrow streets)
• If the distance to the destination is extremely
short or extremely long, route search may be
impossible.
• Even if you travel off the route, the route is
automatically recalculated.
• The estimated time of arrival varies with the
road conditions and how you drive.
