GPS (Global Positioning System)
GPS (Global Positioning System) was developed for and is con-
trolled by the US Department of Defense. The system utilizes GPS
satellites (NAVSTAR), sending out radio waves while flying on an
orbit around the earth at an altitude of approximately 21,000 km
(13,000 miles).
The GPS receiver calculates the vehicle's position in three dimen-
sions (latitude/longitude/altitude) according to the time lag of the
radio waves received from four or more GPS satellites (three-dimen-
sional positioning). If radio waves were received only from three
GPS satellites, the GPS receiver calculates the vehicle's position in
two dimensions (latitude/longitude), utilizing the altitude data calcu-
lated previously with radio waves from four or more GPS satellites
(two-dimensional positioning).
Position correction by GPS is not available while the vehicle is stopped.
Accuracy of GPS will deteriorate under the following conditions:
lIn two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position
changes.
lThe accuracy can be even lower depending on the arrangement of the GPS satellites utilized for the posi-
tioning.
lPosition detection is not possible when vehicle is in an area where radio waves from the GPS satellite do
not reach, such as in a tunnel, parking lot in a building, and under an elevated highway. Radio waves from
the GPS satellites may not be received when some object is located over the GPS antenna.
NOTE:
lEven a high-precision three dimensional positioning, the detection result has an error about 10 m (33 ft).
lBecause the signals of GPS satellite is controlled by the Tracking and Control Center in the United States,
the accuracy may be degraded lower intentionally or the radio waves may stop.
Traffic Information (RDS-TMC)
NOTE:This system is built-in NAVI control unit.
The Traffic Information broadcast allows to you to avoid delays due to traffic incidents.
Traffic jams, roadwork, closed roads around your current location, etc. are represented graphically on the map
by icons depicting the nature of the event.
Incidents on the route are automatically brought to your attention when they are approached.
The Traffic Information feature gives you the opportunity to forecast traffic incidents, determine how serious
they are and, via the guidance mode, allows you to detour around traffic incidents.
The navigation system receives traffic information from best available sources and enables the RDS-TMC
(Radio Data System-Traffic Information Channel) to inform and guide you.
The RDS-TMC broadcast is fed by a dedicated FM tuner so that you can still tune your radio station while Traf-
fic Information is being broadcasted.
HANDS-FREE PHONE
lNAVI control unit has Bluetooth module. It can perform wireless hands-free telephone calls using a cellu-
lar phone in vehicle compartment.
l5 or more portable phones can be registered into the NAVI control unit.

Navigation System Diagnosis FunctionEKS00Q6H
lThere are 2 diagnosis functions (on board diagnosis and diagnosis using CONSULT-II), and it is neces-
sary to use them properly according to the condition. If the on board diagnosis starts, perform diagnosis
with on board diagnosis. If the on board diagnosis does not start (the cause being that the system is not
started, the switch operation is not activated, etc.), perform diagnosis using CONSULT-II.
lAt on board diagnosis, the NAVI control unit diagnosis function starts by switch operation and the NAVI
control unit performs the diagnosis for each unit of system.
lAt diagnosis using CONSULT-II, the NAVI control unit diagnosis function starts by the communication
between CONSULT-II and NAVI control unit, and the NAVI control unit performs the diagnosis for each
unit of system.
On Bord Self-Diagnosis FunctionEKS00Q6I
DESCRIPTION
lThe on board diagnosis function has a self-diagnosis mode for performing trouble diagnosis automatically
and a Confirmation/Adjustment mode for operating manually.
lSelf-diagnosis mode performs the diagnosis at NAVI control unit, connections between each unit that
composes the system, and connections between NAVI control unit and GPS antenna. It displays the
results on the display.
lConfirmation/Adjustment mode is used to monitor the vehicle signals requiring operation and judgement
by a technician (malfunctions that cannot be automatically judged by the system), the confirmation/adjust-
ment of setting value, the error history of system, and the communication condition of system.
DIAGNOSIS ITEM
Mode Description
Self Diagnosis
lNAVI control unit diagnosis (DVD-ROM drive will not be diagnosed when
no map DVD-ROM is in it.)
lThe connection diagnosis between NAVI control unit and GPS antenna
and the connection diagnosis between NAVI control unit and each unit
can be performed.
Confirma-
tion/Adjust-
mentDisplay DiagnosisThe tint can be confirmed by the color spectrum bar display. The shading
of color can be confirmed by the gradation bar display.
Vehicle SignalsDiagnosis of signals can be performed for vehicle speed, parking brake,
lights, ignition (ignition switch), and reverse.
Speaker Test The connection of a speaker can be confirmed by test tone.
NavigationSteering Angle
AdjustmentWhen there is a difference between the actual turning angle and the vehi-
cle mark turning angle, it can be adjusted.
Speed CalibrationWhen there is a difference between the current location mark and the
actual location, it can be adjusted.
Error HistoryThe system malfunction and its frequency that occurred in the past are dis-
played. When the malfunctioning item is selected, the time and place that
the selected malfunction last occurred are displayed.
Vehicle CAN Diagnosis The transmitting/receiving of CAN communication can be monitored.
AV COMM DiagnosisThe communication condition of each unit that composes the system can
be monitored.
Handsfree PhoneEach setting of hands-free volume adjustment, voice microphone test,
delete hands-free memory can be performed.
Bluetooth Passkey and device name can be confirmed/changed.
Delete Unit Commection Log The connection history and error history of unit can be deleted.
