System DescriptionINFOID:0000000003776773
NOTE:
Refer to NAVI System Owner's Manual for system operation.
The navigation system periodically calculates the vehicl e'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 sensor), 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 data, which is stored in the har d disk drive (HDD)(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 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.
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 GP S 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.

System DescriptionINFOID:0000000003776785
Refer to the Owner's Manual for Bluetoot
h 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 equipped cellular telephone to make a wire-
less connection between their cellular telephone and the AV control unit. Hands-free cellular telephone calls
can be sent and received. Personal memos can be created using the Nissan Voice Recognition system. Some
Bluetooth cellular telephones may not be recognized by t he AV control unit. When a cellular telephone or the
AV control unit is replaced, the telephone must be pair ed with the AV control unit. Different cellular telephones
may have different pairing procedures. Refer to the cellular telephone operating manual and the vehicle
Owner’s Manual for more information.
AV CONTROL UNIT
When the ignition switch is turned to ACC or ON, the AV control unit will power up. During power up, the Blue-
tooth feature is initialized and performs various self checks. Initialization may take up to 10 seconds. If a
phone is present in the vehicle and paired with the AV control unit, Nissan Voice Recognition will then become
active. Bluetooth telephone functions can be turned off using the Nissan Voice Recognition system.
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 AV control unit uses this signal to
perform various functions while navigati ng 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
MICROPHONE
The microphone is located in the roof console assembly . The microphone sends a signal to the AV control unit.
The microphone can be actively tested during self-diagnosis.
