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.
Conditions Likely to Cause
Noticeable Positioning Errors
For various reasons such as the state of the road
you are traveling 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 kilometers 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 parking lot.

About the Data being Deleted

The information is erased by pushing the RESET
button or disconnect yellow lead from battery (or
remove the battery itself), except for the following
items.
• Sensor learning status and driving status
• Memory area memorized manually
• Area to avoid
• Registered Locations
Limitation of Functions for

Displaying the Map
• Maps with a scale of between 0.02 mi and 0.25
mi cannot be displayed. (If the scale was set to
between 0.02 mi and 0.25 mi, it is automati-
cally switched to 0.5 mi.)
• When driving with Guide View, Route View
or Driver's View, upon entering an unre-
corded area the display automatically switches
to Map View. (When the vehicle re-enters an
area stored on the disc, the display returns to
the previous map mode except for Driver's
View.)
Destination Search
• You cannot search a destination in an unre-
corded area using Address Search, POI
Search, or Telephone Search. (In case of the
POI search, only "City Center" search is possi-
ble.)
• If you cannot search in a currently selected
zone, the system may forcibly switch to the
zone selection screen.
• A Freeway Search covers all areas, regard-
less of the disc on which the information is
recorded.
• If a Vicinity Search is performed on the bor-
der of an unrecorded area, the system will not
necessarily select the nearest facility. (The
search will take place only within the range of
areas recorded on the disc.)
