NAVIGATION SYSTEM
MAP–MATCHING
Map–matching is a function that repositions the vehicle on the road
map when a new location is judged to be the most accurate. This is
done by comparing the current vehicle position, calculated by the
method described in the position detection principle, with the road
map data around the vehicle, read from the map data stored on the
HDD.
Therefore, the vehicle position may not be corrected after the vehicle
is driven over a certain distance or time in which GPS information is
hard to receive. In this case, the current-location mark on the display
must be corrected manually.
CAUTION:
The road map data is based on data stored on the HDD.
• In map-matching, alternative rout
es to reach the destination will be
shown and prioritized, after the road on which the vehicle is cur-
rently driven has been judged and the current-location mark has
been repositioned.
If there is an error in distance and/or direction, the alternative
routes will be shown in different order of priority, and the wrong
road can be avoided.
If two roads are running in parallel, they are of the same priority.
Therefore, the current-location mark may appear on either of them
alternately, depending on maneuvering of the steering wheel and
configuration of the road.
• Map-matching does not function correctly when the road on which the vehicle is driving is new and not recorded on the HDD, or when
the road pattern stored in the m ap data and the actual road pattern
are different due to repair.
When driving on a road not present in the map, the map-matching
function may find another road and position the current-location
mark on it. Then, when the correct road is detected, the current-
location mark may leap to it.
• Effective range for comparing the vehicle position and travel direc-
tion calculated by the distance and direction with the road data
read from the HDD is limited. Therefore, when there is an exces-
sive gap between the current vehicle position and the position on
the map, correction by map-matching is not possible.
GPS (GLOBAL POSITIONING SYSTEM)
GPS (Global Positioning System) has been developed and con-
trolled by the US Department of Defense. The system utilizes GPS
satellite (NAVSTAR), sending out radio waves while flying on an orbit
around the earth at the height of approx. 21,000 km (13,000 miles).
The GPS receiver calculates the vehicle's position in three dimen-
sions (latitude/longitude/altitude) according to the time lag of the
radio waves received from four or more GPS satellites (three-dimen-
sional positioning). If radio waves were received only from three
GPS satellites, the GPS receiver calculates the vehicle's position in
two dimensions (latitude/longitude), utilizing the altitude data calcu-
lated previously by using radio wa ves from four or more GPS satel-
lites (two-dimensional positioning).
Type Advantage Disadvantage
Gyroscope (angular velocity sensor) • Can detect the vehicle's turning angle quite
accurately. • Direction errors may accumulate when the ve-
hicle is driven for long distances without stop-
ping.
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.

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.
