NAVIGATION

1.

The navigation screen will be shown, and items “Display Longi-
tude & Latitude”, “Speed Calibration”, “Angle Adjustment” and
“Initialize Location” will become selective.

2.

Select each switch on “NAVIGATION” screen to display the rele-
vant diagnosis screen.

GPS ROM 
malfunction
GPS RAM 
malfunction

Contents of ROM (or RAM) in GPS substrate are malfunctioning.

Location detection accuracy of the navigation 
system will deteriorate, depending on the error 
area in the memory, because GPS cannot 
make correct positioning.
(Location correction using GPS is not per-
formed.)

Perform self-diagnosis.

When the NAVI control unit is judged normal by self-diagnosis, 
the symptom may be intermittent, caused by strong radio inter-
ference.

GPS RTC 
malfunction

Clock IC in GPS substrate is malfunctioning.

Correct time may not be displayed.

After the power is turned on, the system 
always takes some time until GPS positioning 
becomes possible. (The GPS receiver starts 
positioning without re-collecting the whole sat-
ellite information when it judged the data 
stored in the receiver is correct.)

Correct time of error occurrence may not be 
stored in the 

Error History

.

Perform self-diagnosis.

When the NAVI control unit is judged normal by self-diagnosis, 
the symptom may be intermittent, caused by strong radio inter-
ference.

GPS antenna 
disconnected

Malfunctioning connection between GPS substrate in NAVI control 
unit and GPS antenna.

Navigation location detection performance 
has deteriorated.
(Location correction using GPS is not per-
formed.)

GPS receiving status remains gray.

Perform self-diagnosis.

When connection between NAVI control unit and GPS antenna 
is judged normal by self-diagnosis, the symptom may be inter-
mittent, caused by impact or vibration.

Low voltage 
of GPS

The power voltage supplied to the GPS circuit board has 
decreased.

Navigation location detection performance 
has deteriorated.
(Location correction using GPS is not per-
formed.)

GPS receiving status remains gray.

Perform self-diagnosis.

When connection between NAVI control unit and GPS antenna 
is judged normal by self-diagnosis, the symptom may be inter-
mittent, caused by impact or vibration.

DVD-ROM 
Response 
Error

Malfunctioning NAVI control unit.

-

Dedicated map DVD-ROM is in the system, but the data cannot be 
read.

The map of a particular location cannot be dis-
played.

Specific guidance information cannot be dis-
played.

Map display is slow.

Guidance information display is slow.

System has been affected by vibration.

Is map DVD-ROM damaged, warped, or dirty?

If damaged or warped, the map DVD-ROM is malfunctioning.

If dirty, wipe the DVD-ROM clean with a soft cloth.

Perform self-diagnosis.

When NAVI control unit is judged normal by self-diagnosis, the 
symptom is judged intermittent, caused by vibration.

Angle adjustment 

Adjusts turning angle output detected by the gyroscope.

Speed Calibration

During normal driving, distance error caused by tire wear and
tire pressure change is automatically adjusted for by the auto-
matic distance correction function. This function, on the other
hand, is for immediate adjustment, in cases such as driving with
tire chain fitted on tires.
