SERVICE

To set Service schedule, change Journey distance with joystick.
At the same time, the marker of journey distance will be moved.

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 “History of Errors”.

Perform the self-diagnosis.

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

GPS antenna
disconnected

Malfunctioning connection between GPS substrate in AV and
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 the self-diagnosis.

When connection between AV and NAVI control unit and GPS
antenna is judged normal by self-diagnosis, the symptom may
be intermittent, 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 the self-diagnosis.

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

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 the self-diagnosis.

When AV and NAVI control unit is judged normal by self-diagno-
sis, the symptom is judged intermittent, caused by vibration.
