Start the driving after closing the opening screen as much as possible. The system is ready
to start during opening screen.

The vehicle position indicator may disappear temporarily after the speed is increased
depending on the vehicle model. This is a normal phenomenon indicating that the system
is calculating the distance correction.
The mobile navigation system uses GPS data for distance correction automatically. It must be
properly calibrated for accurate operation. Perform calibration in any of the following circumstances:
1. When using the navigation system for the very first time after installing the system.
2. When the navigation system is transferred to another vehicle.
3. When the tire pressure is changed, tires are rotated, the spare tire is used, tire size, or
wheel diameter is changed.
4. When deleting the position correction learning results.
Notes
Before Use
Make sure the GPS reception indicator is illuminated on the map screen.
GPS reception indicator Drive the vehicle in an open area for approximately 30-minutes at a speed over 20 kph
(12.5 MPH) while receiving GPS signals.

be disabled.

Voice Guidance

The navigation system is just a support system for the driver. The driver should always
pay attention to the traffic situation to safely make decisions. You may be unable at
times to arrive at your destination due to out-of-date information on a map disc. You
should be especially careful when selecting an urgent destination such as a hospital or
a police station.

Your route may sometimes include roads that are not open to vehicles or are closed
due to traffic regulations. Please comply with the local traffic regulations.

Do not change the settings and destination locations while driving. Minimize the time
spent viewing the monitor screen and listening to the voice guidance while driving.
Operating the system will distract the driver from looking ahead of the vehicle and may
cause an accident. Always stop the vehicle in a safe location and use the parking brake
before operating the system.
Warnings

The system vocally announces the distance to an upcoming highway
branching point or junction.
aThis guidance function can be set in the [Setup menu]. For details, see page 32.

The mobile navigation system calculates and indicates the vehicle position on the map by
multiplying the speed pulse emitted by the vehicle with a correction coefficient.
The speed pulse emitted varies with the type of vehicle and with differences in tire
pressure and wear.
A different correction coefficient might even be required for the same type of vehicle.

Using a spare tire in place of the regular one may cause vehicle position deviations.

If you are using the system for the first time, or if you have not used it for some time, it
takes about 5 minutes (or about 2 minutes in open areas) to calculate your vehicle's
position.

The GPS satellites are controlled by the U.S. Defense Department, which may intentionally
lower positioning accuracy. In such cases, there may be vehicle position deviations.

There may be vehicle position deviations for some time until GPS signals are received after
turning on the ignition.

Map Matching
This function compares your vehicle's tracking data with the road data on the map
disc, applies dead reckoning to determine the road you are driving on,
and displays your vehicle on that road on the map.

Intelligent map matching addresses the following problems to achieve high accuracy
in vehicle positioning.
Position Correction for Elevated RoadsPosition accuracy is improved by detecting if
the vehicle is running on or under an elevated road.

Using a spare tire in place of the regular one may cause vehicle position deviations.

Any difference between the direction which your vehicle actually travels and that shown
on the map is automatically eliminated by azimuth correction.
GPS is a position detecting system utilizing the signals from
GPS satellites deployed by the U.S. Department of Defense.
The Mobile Navigation System uses input from three or more
satellites and calculates the vehicle position based on the
principle of triangulation.
The positioning accuracy of the system corresponds to the
error display of the GPS which is from about 30 to 200 meters.
Position Correction for Parking GaragesPosition accuracy is improved by detecting if the vehicle
is driving in an elevated or underground parking garage.
High-precision GyrosensorA gyro detects turns with an accuracy of 0.05˚ per second.
Combined with a speed sensor, it enables the system to display
the current vehicle position even where GPS signals may be
blocked.
