ESP NISSAN FRONTIER 2007 D22 / 1.G Navigation Manual

.If waypoints are set, the system calculates
multiple routes between waypoints simulta-
neously, and the following may result.
— If one section between waypoints cannot
be calculated, none of the route will be
displayed.
— The route may not connect completely at
some waypoints.
— The route may require a U-turn close to
some waypoints.
.Route calculation may not be completed in
the following cases.
— If there is no main road within a range of
1.5 miles (2.5 km) from the vehicle, a
message saying so will appear on the
screen. Try recalculating when the vehi-
cle is closer to a main road.
— If there is no main road within a range of
1.5 miles (2.5 km) from the destination or
waypoint, a message saying so will
appear on the screen. Try setting the
location closer to a main road.
— If the vehicle is too close to the
destination or if there are no roads to
the destination, a message saying so will
appear on the screen.— If it is impossible to reach the destination
or waypoints because of traffic regula-
tions, etc.
— If the only route to reach the destination
or waypoints is extremely complicated.
— If the destination, current vehicle position
or waypoint is within the “Avoid Area”.
— If a part of the route is included in the
“Avoid Area”.
.The following may occur when the route is
displayed.
— If you calculate a route on a main road,
the starting point of the route may not
exactly match the current vehicle loca-
tion.
— The endpoint of the route may not
exactly match the destination.
— If you calculate a route on a main road,
the system may display a route from
another main road. This may be because
the position of the vehicle icon is not
accurate. In this case, park the vehicle in
a safe location and reset the vehicle
icon, or continue driving to see if the
position of the vehicle icon is automati-
cally adjusted before recalculating the
route.— There are cases in which the system
shows an indirect route to reach the
destination or waypoints, if you set them
from stored or facility information. In
order to correct this, you must be careful
about the traffic direction, especially
when lanes with different travel direc-
tions are shown separately, such as
interchanges and service areas.
— This system makes no distinction be-
tween limited traffic control and total
control (blockage) . It may show an
indirect route even if the road is usable.
— Even if the freeway preference is set to
OFF, a route that uses the freeway may
be suggested.
— Even if the preference is set to OFF, a
route that uses a ferry line may be
suggested.
— Ferry lines, excluding those that are only
for pedestrians, bicycles and motor-
cycles, are stored in this system. Take
into consideration the travel time re-
quired and operational condition before
deciding whether to use them or not.
9-10General system information

INFO:
The announcement of the street name during
route guidance is available only when English is
set as the language for the system. Street
names are not announced if French is set for the
system.
BASICS OF VOICE GUIDANCE
Voice guidance announces which direction to
turn when approaching an intersection in which
a turn is necessary.
NOTE:
.There may be some cases in which
voice guidance and actual road condi-
tions do not correspond. This may
occur because of discrepancies be-
tween the actual road and the informa-
tion on the DVD-ROM, or it is due to the
vehicle’s speed.
.In case voice guidance does not corre-
spond to the actual road conditions,
follow the information obtained from
traffic signs or notices on the road..Route guidance provided by the navi-
gation system does not take carpool
lane driving into consideration, espe-
cially when carpool lanes are separated
from other road lanes.
DIRECTIONS PROVIDED AND THE
DISTANCES TO GUIDE POINTS
Directions will differ, depending on the road
type.
INFO:
Distances may vary, depending on the vehicle
speed.
ROUTE GUIDANCE
General system information9-11

The display is a liquid crystal display and should
be handled with care.
WARNING
Never disassemble the display. Some
parts utilize extremely high voltage.
Touching them may result in serious
personal injury.
CHARACTERISTICS OF A LIQUID
CRYSTAL DISPLAY
.If the temperature inside the vehicle is
especially low, the display will stay relatively
dim or the movement of the images may be
slow. These conditions are normal. The
display will function normally when the
interior of the vehicle has warmed up.
.Some pixels in the display are darker or
brighter than others. This condition is an
inherent characteristic of liquid crystal dis-
plays, and it is not a malfunction.
.You may also notice a remnant of the
previous display image on the screen. This
screen burn is inherent in displays, and it is
not a malfunction.
INFO:
The screen may become distorted by strong
magnetic fields.
MAINTENANCE OF THE DISPLAY
CAUTION
.To clean the display, never use a
rough cloth, alcohol, benzine, thinner
and any kind of solvent or paper towel
with a chemical cleaning agent. They
will scratch or deteriorate the panel.
.Do not splash any liquid such as water
or car fragrance on the display. Con-
tact with liquid will cause the system
to malfunction.
If you need to clean the display screen, use a
dry, soft cloth. If additional cleaning is necessary,
use a small amount of neutral detergent with a
soft cloth. Never spray the screen with water or
detergent. Dampen the cloth first, then wipe the
screen.
HOW TO HANDLE THE DISPLAY
9-20General system information

Symptom Possible cause Possible solution
An indirect route is suggested. If there are restrictions (such as one-way streets) on roads close to the
starting point or destination, the system may suggest an indirect route.Adjust the location of the starting point or destination.
The system may suggest an indirect route because route calculation
does not take into consideration some areas such as narrow streets
(gray roads) .Reset the destination to a main or ordinary road, and
recalculate the route.
The landmark information does not
correspond to the actual information.This may be caused by insufficient or incorrect data on the DVD-ROM. Updated information will be included in the next version
of the map DVD-ROM.
The suggested route does not exactly
connect to the starting point, waypoints,
or destination.There is no data for route calculation closer to these locations. Set the starting point, waypoints and destination on a
main road, and perform route calculation.
10-8Troubleshooting guide

Symptom Possible cause Possible solution
Voice guidance is not available. Voice guidance is only available at certain intersections marked with
.
In some cases, voice guidance is not available even when the vehicle
should make a turn.This is not a malfunction.
The vehicle has deviated from the suggested route. Go back to the suggested route or request route
calculation again.
Voice guidance is set to off. Turn on voice guidance.
Route guidance is set to off. Turn on route guidance.
The guidance content does not correspond
to the actual condition.The content of voice guidance may vary, depending on the types of
intersections at which turns are made.Follow all traffic rules and regulations.
