Component DescriptionNKS002QA
NAVI CONTROL UNIT

NAVI control unit connects to the display unit and NAVI switch
with communication lines.

The gyro (angular speed sensor) and the DVD-ROM drive are
built-in units that control the navigation functions.

Signals are received from the gyro, the vehicle speed sensor,
and the GPS antenna. Vehicle location is determined by com-
bining these data with the data contained in the DVD-ROM map.
Locations information is shown on display unit.

NAVI control unit outputs ON signal and voice guidance signal to
audio unit.
DVD-ROM Drive
Maps, traffic control regulations, and other pertinent information can
be easily read from the DVD-ROM (1).
DVD-ROM

The DVD-ROM has maps, traffic control regulations, and other pertinent information.

To improve DVD-ROM map matching and route determination functions, the DVD-ROM uses an exclusive
Nissan format. Therefore, the use of a DVD-ROM provided by other manufacturers cannot be used.
Gyro (Angular Speed Sensor)

The oscillator gyro sensor is used to detect changes in vehicle steering angle.

The gyro is built into the NAVI control unit.
GPS ANTENNA
The GPS antenna receives and amplifies the radio waves from the
GPS satellites, and then transmits the GPS signal to NAVI control
unit.

HANDS-FREE PHONE SYSTEM

For Hands-free phone system operation information, refer to Owner's Manual.

TEL adapter unit has Bluetooth® module. It can perform wireless hands-free telephone calls using a cel-
lular phone in vehicle compartment.

5 or less cellular phones can be registered into the TEL adapter unit.

Hands-free phone mode starts by transmitting steering switch signal to TEL adapter unit when pressing
button.

Hands-free phone mode ends by transmitting steering switch signal to TEL adapter unit when pressing
button.

When uttering to the TEL microphone, TEL microphone signal (audio signal) is transmitted from the TEL
microphone to the TEL adapter unit and transmitted to the cellular phone with the Bluetooth
® communi-
cation.

Audio signals from a party at the other end are transmitted from the cellular phone to the TEL adapter unit
with the Bluetooth
® communication, and transmitted from the TEL adapter unit to the audio unit, then the
party's voice is output from the front door speaker.

Audio unit switches the voice from front speaker RH to TEL voice when receiving TEL ON signal from TEL
adapter unit.
