AUDIO ANTENNAPFP:28200
System DescriptionEKS00BJ1
With the ignition switch in ACC or ON, power is supplied

through 10A fuse [No. 4, located in the fuse block (J/B)]

to audio unit terminal 10.
Ground is supplied through the case of the antenna amp.
When the audio unit switch is turned ON, antenna signal is supplied

through audio unit terminal 5

to the antenna amp. terminal 1.
Then the antenna amp. is activated.
The amplified radio signals are supplied to the audio unit through the antenna amp.

BLUETOOTH® HANDS-FREE PHONE SYSTEM
Refer to the Owner's Manual for Bluetooth telephone system operating instructions.
NOTE:
Cellular telephones must have their wireless connection set up (paired) before using the Bluetooth telephone
system.
Bluetooth telephone system allows users who have a Bluetooth cellular telephone to make a wireless connec-
tion between their cellular telephone and the Bluetooth control unit. Hands-free cellular telephone calls can be
sent and received. Personal memos can be created using the Infinity Voice Recognition system. Some Blue-
tooth cellular telephones may not be recognized by the Bluetooth control unit. When a cellular telephone or
the Bluetooth control unit is replaced, the telephone must be paired with the Bluetooth control unit. Different
cellular telephones may have different pairing procedures. Refer to the cellular telephone operating manual.
Bluetooth Telephone System Diagram
Bluetooth Control Unit
When the ignition switch is turned to ACC or ON, the Bluetooth control unit will power up. During power up, the
Bluetooth control unit is initialized and performs various self checks. Initialization may take up to 10 seconds.
During this time the Bluetooth ON indicator will flash until initialization is complete. Infinity Voice Recognition
will then become active and the Bluetooth ON indicator will remain on. Bluetooth telephone functions can be
turned off using the voice recognition system.
BCM
The BCM supplies power for the Bluetooth ON indicator.
Steering Wheel Audio Control Switches
When buttons on the steering wheel audio control switch are pushed, the resistance in steering wheel audio
control switch circuit changes depending on which button is pushed. The Bluetooth control module uses this
signal to perform various functions while navigating through the voice recognition system.
The following functions can be performed using the steering wheel audio control switch:

Initiate Self Diagnosis of the Bluetooth telephone system

Start a voice recognition session

Answer and end telephone calls

Adjust the volume of calls

Record memos
AV S w i t c h
Call volume can be adjusted using the AV switch.

NAVIGATION SYSTEM
Revision: November 20092006 QX56
NAVIGATION SYSTEMPFP:25915
System DescriptionEKS00BJD
NOTE:
Refer to NAVI System Owner's Manual for system operation.
The navigation system periodically calculates the vehicle's current
position according to the following three signals: Travel distance of
the vehicle as determined by the vehicle speed sensor, turning angle
of the vehicle as determined by the gyroscope (angular velocity sen-
sor), and the direction of vehicle travel as determined by the GPS
antenna (GPS information).
The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data read from the map DVD-
ROM, which is stored in the DVD-ROM drive (map-matching), and
indicated on the screen with a current-location mark.
By comparing the vehicle position detection results found by the
GPS and by map-matching, more accurate vehicle position data can
be used.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.
TRAVEL DISTANCE
Travel distance calculations are based on the vehicle speed sensor input signal. Therefore, the calculation
may become incorrect as the tires wear down. To prevent this, an automatic distance fine adjustment function
has been adopted. Adjustments can be made in extreme cases (such as driving with tire chain fitted on tires).
Refer to AV- 11 7 , "
Confirmation/Adjustment Mode" .
TRAVEL DIRECTION
Change in the travel direction of the vehicle is calculated by a gyroscope (angular velocity sensor) and a GPS
antenna (GPS information). As the gyroscope and GPS antenna have both merit and demerit, input signals
from them are prioritized in each situation. However, this order of priority may change in accordance with more
detailed travel conditions so that the travel direction is detected more accurately.
WKIA1371E
SEL684V
Type Advantage Disadvantage
Gyroscope (angular velocity sensor)

Can detect the vehicle's turning angle
quite accurately.
Direction errors may accumulate when the
vehicle is driven for long distances without
stopping.
GPS antenna (GPS information)

Can detect the vehicle's travel direction
(North/South/East/West).
Correct direction cannot be detected when
the vehicle speed is low.
