The audio system is equipped with following function. Each function is operated with audio switch or steering
switch.
FUNCTION DESCRIPTION
Operating signal
Audio system operation can be performed with audio switch or steering switch.
AM/FM Radio Mode
AM/FM radio tuner is built into AV control unit.
Audio signal is received by antenna, next it is input to AV control unit. AV control unit outputs the audio signal
to each speaker.
CD Mode
CD function is built into AV control unit.
AV control unit outputs audio signal to each speaker when CD is inserted to AV control unit.
Hands-free phone system
Hands-free communication can be operated by connecting using Bluetooth® with cellular phone.
Operation is performed by steering switch.
Guide sound that is heard during operation is output from AV control unit to front speaker.
When a call is originated
Spoken voice sound output from the microphone (Mic. Signal) is input to AV control unit. AV control unit out-
puts to cellular phone with Bluetooth
® communication as a TEL voice signal. Voice sound is then heard at
the other party.
When receiving a call Voice sound is input to own cellular phone from the other party. TEL voice signal is output to front speaker,
and the signal is input to AV control unit by establishing Bluetooth
® communication from cellular phone.

P Description
The link with the NATS IMMU implies that the AV control unit can basically only be operated if connected to the
matching NATS IMMU to which the AV control unit was initially fitted on the production line.
Since radio operation is impossible after the link with the NATS is disrupted, theft of the AV control unit is basi-
cally useless since special equipment is required to reset the AV control unit.
Initialization Process for AV control units That Are Linked to the NATS IMMU
New AV control units will be delivered to the factories in the “NEW” state, i.e. ready to be linked with the vehi-
cle's NATS. When the AV control unit in “NEW” state is first switched on at the factory, it will start up communi-
cation with the vehicle's immobilizer control unit (IMMU) and send a code (the “AV control unit Code”) to the
IMMU. The IMMU will then store this code, which is unique to each AV control unit, in its (permanent) memory.
Upon receipt of the code by the IMMU, the NATS will confirm correct receipt of the AV control unit code to the
AV control unit. Hereafter, the AV control unit will operate as normal.
During the initialization process, “NEW” is displayed on the AV control unit display. Normally though, communi-
cation between AV control unit and IMMU takes such a short time (300 ms) that the AV control unit seems to
switch on directly without showing “NEW” on its display.
Normal Operation
Each time the AV control unit is switched on afterwards, the AV control unit code will be verified between the
AV control unit and the NATS before the AV control unit becomes operational. During the code verification pro-
cess, “WAIT” is shown on the AV control unit display. Again, the communication takes such a short time (300
ms) that the AV control unit seems to switch on directly without showing “WAIT” on its display.
When The Radio Is Locked
In case of the AV control unit being linked with the vehicle's NATS (immobilizer system), disconnection of the
link between the AV control unit and the IMMU will cause the AV control unit to switch into the lock
(“SECURE”) mode in which the AV control unit is fully inoperative. Hence, repair of the AV control unit is basi-
cally impossible, unless the AV control unit is reset to the “NEW” state for which special decoding equipment is
required.
Clarion has provided their authorized service representatives with so called “decoder boxes” which can bring
the AV control unit back to the “NEW” state, enabling the AV control unit to be switched on after which repair
can be performed. Subsequently, when the repaired AV control unit is delivered to the final user again, it will
be in the “NEW” state to enable re-linking the AV control unit to the vehicle's immobilizer system. As a result of
the above, repair of the AV control unit can only be done by an authorized Clarion representative (when the
owner of the vehicle requests repair and can show personal identification).
Service Procedure
Item Service procedure Description
Battery disconnection No additional action required. –
Radio needs repair Repair needs to be done by authorized rep-
resentative of radio manufacturer since ra-
dio cannot be operated unless it is reset to
NEW state, using special decoding equip-
ment.–
Replacement of radio by new part No additional action required. Radio is delivered in “NEW” state.
Transferring radio to another vehicle/re-
placement of radio by an old partRadio needs to be reset to NEW state by
authorized representative of radio manu-
facturer.–
Replacement of IMMU Radio needs to be reset to NEW state by
authorized representative of Clarion.After switching on the radio, it will display
“SECURE” after 1 minute.
No communication from IMMU to radio 1. Check NATS system if NATS is mal-
functioning.
2. Reset radio to “NEW” state by autho-
rized representative of Clarion after
NATS is repaired.The radio will display “SECURE” after 1
minute after switching on the radio. Further
use of radio is impossible until communica-
tion is established again, or after radio is re-
set by authorized representative of Clarion.
When initialized between ECM and IMMU. Radio needs to be reset to “NEW” status by
authorized representative of Clarion.It will display “SECURE” after 1 minute after
switching on the radio.

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
(13,100miles).
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). The GPS receiver calculates the vehicle's posi-
tion in two dimensions (latitude/longitude), utilizing the altitude data
calculated previously with radio waves from four or more GPS satel-
lites (two-dimensional positioning) if radio waves were received only
from three GPS satellites.
Position correction by GPS is not available while the vehicle is stopped.
Accuracy of GPS will deteriorate under the following conditions:
In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position changes.
The accuracy can be even lower depending on the arrangement of the GPS satellites utilized for the posi-
tioning.
Position 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:
Even a high-precision three dimensional positioning, the detection result has an error about 10 m (30ft).
Because 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, via the guidance mode, and 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.
