SymptomPossible cause Possible solution
When a cellular phone is operated to make
a call, the hands-free function becomes
unavailable. Some models of a cellular phone do not switch
to the hands-free mode when they are operated
to make a call. This is not a malfunction. Make a call again using the
hands-free function.
The other party’s voice cannot be heard.
There is no ring tone. The volume level is set to the minimum. Adjust the volume level.
A cellular phone is not connected.
Check the registration procedure, and then register
the cellular phone again.
Each volume level (ring tone, incoming
voice or outgoing voice) is different. Each volume level is not adjusted properly. Adjust each volume level properly.
The antenna display is different between
the navigation screen and a cellular phone
screen. Making or receiving a call is un-
available even though the antenna display
shows that it is possible to do so. The antenna display varies depending on the
model of cellular phone.
This does not indicate a malfunction. The antenna
display and remaining battery level shown on the
navigation screen may be different from those shown
on the cellular phone screen. Use them as a reference.
A voice cannot be heard clearly when using
a cellular phone behind tall buildings. Some structures such as tall buildings, etc. may
cause irregular reflection of radio waves or
completely shut out radio waves that are used
for cellular phones. This is not a malfunction.
Noise is heard when using a cellular phone
under/near areas of elevated railroads,
high voltage electric power cables, traffic
signals, neon billboards, etc. Electromagnetic waves that are generated from
radio devices may adversely affect the cellular
phone.
This is not a malfunction.
Noise is heard in the sound from the audio
system while using a cellular phone. Radio waves that are generated from a cellular
phone may adversely affect the sound from the
audio system. This is not a malfunction.
Sound skip. The cellular phone may have turned on wireless

VEHICLE ICON
SymptomPossible 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 cluttered.
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 period of time on a road
where GPS signals can be received.
The position and direction of the vehicle icon may be
incorrect 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 period of time to automatically correct the
position and direction of the vehicle icon.
“Current vehicle location” (page 9-59)
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
system automatically places the vehicle icon on the nearest
road available. Updated road information will be included in
the next version of the map data.
The screen does not switch to the night
screen even after turning on the head-
lights. The daytime screen was set the last time the headlights
were turned on.
