System Description

INFOID:0000000001728606

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.

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  part

Radio 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.
