Cause
The GPS antenna is in an unsuitable
location.
Obstacles are blocking signals from
the satellites.
The position of satellites relative to
your vehicle is inadequate.
Signals from the GPS satellites have
been modified to reduce accuracy.
(GPS satellites are operated by the
US Department of Defense, and the
US government reserves the right to
distort positioning data for military
reasons. This may lead to greater
positioning errors.)
If a vehicle phone or cellular phone
is used near the GPS antenna, GPS
reception may be lost temporarily.
Something covers the GPS antenna. Do not cover the GPS antenna with spray
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.
An improper value has been set on
"Brightness".
An improper value has been set on
"Brightness".
The volume level is low.
A speaker lead is disconnected.
MULTI-CONTROL is used to adjust
the volume.
Action (Reference)
The quality of signals from the GPS satellites
is poor, causing reduced positioning accu-
racy. Check the GPS signal reception and the
position of the GPS antenna if necessary.
The quality of signals from the GPS satellites

position of the GPS antenna if necessary, or
continue driving until reception improves.
Keep the antenna clear.

paint or vehicle wax, because this may block
the reception of GPS signals. Snow buildup
can also degrade the signals.
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
