Power is supplied at all times
 through 15A fuse (No. 32, located in the fuse and fusible link block)
 to audio unit terminal 6
 to A/C and AV switch terminal 1
 to display control unit terminal 1
 to woofer terminal 1
 to satellite radio tuner terminal 12 (With satellite radio) and
 to option connector–2 for satellite radio tuner terminal 12 (Without satellite radio),
 through 20A fuse [No.17, located in the fuse block (J/B)]
 to BOSE speaker amp. terminal 1.
With the ignition switch in the ACC or ON position, power is supplied
 through 10A fuse [No. 6, located in the fuse block (J/B)]
 to audio unit terminal 10
 to A/C and AV switch terminal 2
 to display control unit terminal 10
 to satellite radio tuner terminal 16 (With satellite radio) and
 to option connector–2 for satellite radio t uner terminal 11 (Without satellite radio).
Ground is supplied through the case of the audio unit.
Ground is also supplied
 to BOSE speaker amp. terminal 17

 through body ground M35, M45 and M85.
Audio unit, A/C and audio controller are c onnected by FPC (Flexible Print Circuit).
A/C and audio controller integrates A/C switches and audio switches.
When A/C and audio controller is pressed to audio swit ch, it sends audio signal to audio unit. Then audio sig-
nals are supplied
 through audio unit terminals 1, 2, 3, 4, 13, 14, 15, and 16
 to BOSE speaker amp. terminals 23, 24, 25, 26, 27, 28, 29, and 30.
Audio signals are amplified by the BOSE speaker amp.
The amplified audio signals are supplied
 through BOSE speaker amp. terminals 2, 3, 4, 9,10,11,12, 13, 14, 15, 16, 18, 19 and 20
 to terminals 1 and 2 of front door speaker LH and RH

AUDIO
NOTE:
Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise
from trains and other source s. 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.
 Multi-path noise: This noise results from a time di fference between the broadcast waves directly from the
station arriving at the antenna and the waves reflected by mountains or buildings.
