Trouble DiagnosisNKS002ED
The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interfer-
ence, etc.). Check the symptoms below to diagnose the malfunction.
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunction-
ing. Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and
operation of each piece of electrical equipment, and then determine the cause.
Refer to "SERVICE BULLETIN NTB04-119" for the diagnosis of satellite radio.
NOTE:
Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise
from trains and other sources. It is not a malfunction.
Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-
tains or buildings blocking the signal.

Removal and Installation of Audio Unit (Base system)NKS002BH
REMOVAL
1. Remove cluster lid C. Refer to IP-10, "INSTRUMENT PANEL ASSEMBLY" .
2. Remove screws (A), and remove audio unit (1).
3. Remove screws (8), and remove bracket.
INSTALLATION
Installation is the reverse order of removal.
Locking CD Auto Changer Mechanism (Audio unit of BOSE system)NKS002BI
CAUTION:
Prior to removing a malfunctioning CD auto changer unit (Audio unit of BOSE system) that will be
shipped for repair, the changer mechanism MUST BE LOCKED to prevent the mechanism from
being damaged during shipping.
If a CD is jammed or unable to be removed from the unit, do NOT lock the changer mechanism. If
the unit is to be shipped for repair, carefully package the unit to prevent vibration and shock.
DAMPER LOCK PROCEDURE
1. Eject and remove any CDs from the audio unit (BOSE system).
2. Turn ignition switch OFF. Wait until audio unit (BOSE system) display is off and mechanism stops moving
(mechanism sound stops).
3. Press any one of the disc selection buttons once. When a display shows on the audio unit (BOSE sys-
tem), press the same disc selection button again within 5 seconds.
The changer mechanism will lock itself within 10 seconds.
4. After mechanism stops moving (mechanism sound stops), open the driver and passenger window, and
then disconnect negative battery cable.
CAUTION:
After the battery cables are disconnected, do not open/close the driver and/or front passenger door
with the window in the full up position. The automatic window adjusting function will not work and the
side roof panel may be damaged.
NOTE:
After installing a new or remanufactured audio unit (BOSE system), switching the audio unit (BOSE system)
ON will automatically unlock the mechanism. A special unlocking procedure is not required.

ANTENNA
Revision: 2006 November2007 350Z
ANTENNAPFP:28200
System DescriptionNKS002EG
With the ignition switch in ACC or ON, power is supplied
through 10A fuse [No. 6, located in the fuse block (J/B)]
to audio unit terminal 10.
Ground is supplied through the case of the antenna amp.
When the radio switch is turned ON, antenna signal is supplied
through audio unit terminal 5
to antenna amp. terminal 1.
Then the antenna amp. is activated.
Antenna signals amplified by the antenna amp. are supplied to the audio unit.
