NAVIGATION SYSTEM
Revision: 2004 November 2004 FX35/FX45
NAVIGATION SYSTEMPFP:25915
System DescriptionAKS00BMX
The navigation system periodically calculates the vehicle's current
position according to the following three signals: Travel distance of
the vehicle as determined by the vehicle speed sensor, turning angle
of the vehicle as determined by the gyroscope (angular velocity sen-
sor), and the direction of vehicle travel as determined by the GPS
antenna (GPS information).
The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data read from the map DVD-
ROM, which is stored in the DVD-ROM drive (map-matching), and
indicated on the screen with a current-location mark.
By comparing the vehicle position detection results found by the
GPS and by map-matching, more accurate vehicle position data can
be used.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.
TRAVEL DISTANCE
Travel distance calculations are based on the vehicle speed sensor input signal. Therefore, the calculation
may become incorrect as the tires wear down. To prevent this, an automatic distance fine adjustment function
has been adopted.
TRAVEL DIRECTION
Change in the travel direction of the vehicle is calculated by a gyroscope (angular velocity sensor) and a GPS
antenna (GPS information). As the gyroscope and GPS antenna have both merit and demerit, input signals
from them are prioritized in each situation. However, this order of priority may change in accordance with more
detailed travel conditions so that the travel direction is detected more accurately.
MAP-MATCHING
Map-matching is a function that repositions the vehicle on the road
map when a new location is judged to be the most accurate. This is
done by comparing the current vehicle position, calculated by the
method described in the position detection principle, with the road
map data around the vehicle, read from the map DVD-ROM stored in
the DVD-ROM drive.
Therefore, the vehicle position may not be corrected after the vehicle
is driven over a certain distance or time in which GPS information is
hard to receive. In this case, the current location mark on the display
must be corrected manually.
CAUTION:
The road map data is based on data stored in the map DVD-
ROM.

TIRE PRESSURE

Pressure indication in psi on the screen indicates that the
pressure is being measured. After a few driving trips, the pres-
sures for all four tires will be displayed.

The order of tire pressure figures displayed on the screen does
not correspond with the actual order of the tire position.

Tire pressure rises and falls depending on the heat caused by
the vehicle's traveling condition and the temperature.

In case of low tire pressure, the low tire pressure warning light
will come on and/or a warning is displayed on the screen.

FLAT TIRE–very low tire air pressure.
NOTE:

In a case of FLAT TIRE pressure, interrupt screen is not shown on the display.

On the screen of TIRE PRESSURE, “FLAT TIRE”, “Check”, “All tire” is displayed.
WARNING INDICATIONS
Warning signal (door switch signal) is received from BCM through
CAN communication line.

Angle Adjustment

Adjusts turning angle output detected by the gyroscope.
Speed Calibration

During normal driving, distance error caused by tire wear and
tire pressure change is automatically adjusted for by the auto-
matic distance correction function. This function, on the other
hand, is for immediate adjustment, in cases such as driving with
tire chain fitted on tires.

PlaceIn a parking lot When driving in a parking lot, or other loca-
tion where there are no roads on the map,
matching may place the vehicle mark on a
nearby road. When the vehicle returns to
the road, the vehicle mark may have devi-
ated from the correct location.
When driving in circle or turning the steer-
ing wheel repeatedly, direction errors accu-
mulate, and the vehicle mark may deviate
from the correct location.
If after travelling about 10km
(6miles) the correct location
has not been restored, perform
location correction and, if nec-
essary, direction correction. Turn ta ble
When the ignition switch is OFF, the navi-
gation system cannot get the signal from
the gyroscope (angular speed sensor).
Therefore, the displayed direction may be
wrong and the correct road may not be
easily returned to after rotating the vehicle
on a turn table with the ignition OFF.
Slippery roads On snow, wet roads, gravel, or other roads
where tires may slip easily, accumulated
mileage errors may cause the vehicle mark
to deviate from the correct road.
Slopes When parking in sloped garages, when
travelling on banked roads, or in other
cases where the vehicle turns when tilted,
an error in the turning angle will occur, and
the vehicle mark may deviate from the
road.
Map dataRoad not displayed on the map screen
When driving on new roads or other roads
not displayed on the map screen, map
matching does not function correctly and
matches the location to a nearby road.
When the vehicle returns to a road which is
on the map, the vehicle mark may deviate
from the correct road.
Different road pattern
(Changed due to repair)
If the road pattern stored in the map data
and the actual road pattern are different,
map matching does not function correctly
and matches the location to a nearby road.
The vehicle mark may deviate from the
correct road.
Vehicle Use of tire chainsWhen tire chains are used, the mileage is
not correctly detected, and the vehicle
mark may deviate from the correct road.Drive the vehicle for a while. If
the distance is still deviated,
adjust it by using the distance
adjustment function. (If the tire
chain is removed, recover the
original value.) Cause (condition) –: While driving ooo: Display Driving condition Remarks (correction, etc.)
