System DescriptionINFOID:0000000001328672
AUDIO SYSTEM
Refer to Owner's Manual for audio system operating instructions.
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
 to woofer terminal 2
 to satellite radio tuner terminal 15 (With satellite radio) and
 to option connector–2 for satellite radio receiver terminal 10 (Without satellite radio)
 through body ground B203 and B210,
 to A/C and AV switch terminal 5
 to display control unit terminals 3,13 and
 to display terminal 1
 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
 to terminals 1 and 2 of rear door speaker LH and RH
 to terminals 1 and 2 of tweeter LH and RH
 to terminals 1 and 2 of instrument speaker LH, RH, and CENTER, and
 to terminals 7 and 8 of woofer.
When one of audio steering wheel switch is press ed to ON (With telephone system), mode ON (Without
telephone system), seek up, or volume up, resistanc e in steering switch circuit changes depending on which
button is pressed.
When one of audio steering wheel switch is pressed to mode ON (With telephone system), power ON (Without
telephone system), seek down, or volume down, resi stance in audio steering wheel switch circuit changes
depending on which button is pressed.
SPEED SENSITIVE VOLUME SYSTEM
Volume level of this system gone up and down automatical ly in proportion to the vehicle speed. And the con-
trol level can be selected by the customer.
