En
Cause
Something covers the GPS antenna. Do not cover the GPS antenna with spray
Signals from the vehicle's speed
pulse are not being picked up prop-
erly.
The navigation system may not be
mounted securely in your vehicle.
The navigation system is installed
with an extreme angle exceeding
the installation angle limitations.
Indication of the position of your ve-
hicle is misaligned after a U-turn or
reversing.
The navigation system is unable to
obtain past average fuel mileage
data, so "Eco Graph" cannot be dis-
played.
"Day/Night Display" is set to
"Day".
The orange/white lead is not con-
nected.
Picture quality adjustment of the
display is not correct.
The vehicle's light is turned ON, and
"Automatic" is selected on "Day/
Night Display".
Picture quality adjustment of the
display is not correct.
The volume level is low.
The attenuator or mute is on.
A speaker lead is disconnected.
VOL (+/–) button or Multi-control is
used to adjust the volume.
The voice from the person on the
other end of the phone call is output
from the speakers and then picked
up by the microphone again, creat-
ing an echo.
Action (Reference)
paint or vehicle wax, because this may block
the reception of GPS signals. Snow buildup
can also degrade the signals.
Check that the cables are properly connected.
If necessary, consult the dealer that installed
the system.
Check that the navigation system is securely
mounted and, if necessary, consult the dealer
that installed the system.
Confirm the installation angle. (The naviga-
tion system must be installed within the al-
lowed installation angle. For details, refer to
Installation Manual.)
Check whether or not the reverse gear signal
input lead (violet) is connected properly. (The
navigation system works properly without the
lead connected, but positioning accuracy will
be adversely affected.)
Drive about 10 km on a road without obstruc-
tions. Then park your vehicle in a safe place,
turn off the navigation system and turn the
power to the navigation system back on.
Check "Day/Night Display" setting and
make sure "Automatic" is selected. (Page
