Symptom Possible cause Possible solution
Names of roads and locations differ between Plan
view and Birdview™This is because the quantity of the displayed information is
reduced so that the screen does not become too crowded.
There is also a chance that names of the roads or locations
may be displayed multiple times, and the names appearing
on the screen may be different because of a processing
procedure.This is not a malfunction.
The vehicle icon is not displayed in the correct
position.The vehicle was transported after the ignition switch was
pushed off, for example, by a ferry or car transporter.Drive the vehicle for a while on a road where GPS signals can
be received.
The position and direction of the vehicle icon may be incor-
rect depending on the driving environments and the levels of
positioning accuracy of the navigation system.This is not a malfunction. Drive the vehicle for a while to auto-
matically correct the position and direction of the vehicle icon.
“CURRENT VEHICLE LOCATION” (page 10-4)
When the vehicle is traveling on a new road, the
vehicle icon is located on another road nearby.Because the new road is not stored in the map data, the sys-
tem automatically places the vehicle icon on the nearest road
available.Updated road information will be included in the next version of
the map DVD-ROM.
The screen does not switch to the night screen
even after turning on the headlights.The daytime screen was set the last time the headlights were
turned on.Set the screen to the night screen mode using the Day/Night
button when you turn on the headlights.

The location of the vehicle icon is misaligned from
the actual position.When using tire chains or replacing the tires, speed calcula-
tions based on the speed sensor may be incorrect.Drive the vehicle for a while (at approximately 19 MPH [30 km/h]
for about 30 minutes) to automatically correct the vehicle icon
position. If this does not correct the vehicle icon position, con-
tact a NISSAN dealer.
The map data has a mistake or is incomplete (the vehicle
icon position is always misaligned in the same area) .Updated road information will be included in the next version of
the map DVD-ROM.
