Operation Manual
Vehicles that Cannot Obtain
Speed Pulse Data
The speed pulse data comes from the speed
sensing circuit. The location of this speed
sensing circuit depends on your vehicle model. In
some cases, it is impossible to make a
connection to it, and in such a case we
recommend that the ND-PG1 speed pulse
generator (sold separately) be used.
• Be sure to connect the speed pulse lead. If
not, vehicle location error will increase.
Conditions Likely to Cause
Noticeable Positioning Errors
For various reasons such as the state of the road
you are travelling on and the state of reception of
the GPS signal, the actual position of your vehicle
may differ from the position displayed on the map
screen.
Some types of vehicle may not output a speed
signal while driving at just a few kilometres per
hour. In such a case, the current location of your
vehicle may not be displayed correctly while in a
traffic jam or in a car park.
• The current vehicle position cannot be
displayed exactly under all conditions, due to
variations in satellite reception, road
conditions, the vehicle's condition, and any
objects in contact with the aerial.
• Also, GPS reception may be unavailable during
certain weather conditions, when driving in
tunnels or garages, or when signal
interference may occur such as when driving
between tall buildings or near large vehicles.

Handling and Care of the Disc

Appendix of the Some basic precautions are necessary when
handling your discs.

Navigation map discs

• Do not use discs other than those intended for
this product. Use only discs approved by
Pioneer.

DVD drive and care

• Use only normal, round discs. If you insert
irregular, non-round, shaped discs they may
jam in the DVD drive or not play properly.
• Check all discs for cracks, scratches or
warping before playing. Discs that have cracks,
scratches or are warped may not play properly.
Do not use such discs.
• Avoid touching the recorded (non-printed side)
surface when handling the disc.
• Store discs in their cases when not in use.
• Keep discs out of direct sunlight and do not
expose the discs to high temperatures.
• Do not attach labels, write on or apply
chemicals to the surface of the discs.
• To clean dirt from a disc, wipe the disc with a
soft cloth outward from the centre of the disc.
• If the heater is used in cold weather,
condensation may form on components inside
the DVD drive. Condensation may cause the
DVD drive to not operate properly. If you think
that condensation is a problem turn off the
DVD drive for an hour or so to allow the DVD
drive to dry out and wipe any damp discs with a
soft cloth to remove the moisture.
• Road shocks may interrupt disc playback.

If you wish to use other navigation discs,
first check that they are compatible with
this equipment and approved by Pioneer.
