• In memory navi mode, map scale data that

cannot be read in the memory cannot be dis-
played. Accordingly, the edge of the map will
appear cut off along the point it was not read
into memory. This simply indicates the edge of
the map data, and is not a malfunction.

• If you keep driving or scrolling the map to a

point where the map can no longer be dis-
played, the scale automatically switches to a
range possible to display. If you would like to
continue driving or scrolling the map at the
same scale, set the DVD Map Disc in the navi-
gation system.

• You cannot reroute to avoid traffic jam or clo-

sure.

• If you continue to drive outside the route for a

while, you may not be able to perform map
matching.

• If you deviate from the route during memory

navi mode, the set route will be rerouted, but
only to return you to the original route calcu-
lated within the memorised area.

• Although an enlarged map of the intersection

will be displayed, no special motorway illustra-
tion (illustration of motorway junctions) will be
displayed.

• Voice recognition functions face some limita-

tions compared to DVD navi mode.

• In memory navi mode, the voice function to

inform you of traffic jam or closure forming on
the route does not function.

Cautions relating to auto reroute

in memory navi mode

Auto rerouting in memory navi mode is designed
to return you to your original route wherever pos-
sible.
In memory navi mode, persistently deviating from
the route may result in one of the following:
• A clearly circuitous route
• Leaving a toll road and returning to the toll

road from where you left it.

In the above case, if the set route seems unsuita-
ble, insert the DVD Map Disc. Setting the DVD
Map Disc to navigation automatically resets the
route from your current location to your destina-
tion.

TMC icon during the memory

navi mode

• TMC-related data for one country only can be

memorised. Therefore, if

appears on

the screen when crossing an international bor-
der, you will need to insert the disc to use the
RDS-TMC function. Touching

allows

you to check the locations of the traffic infor-
mation along the route. However, you cannot
perform rerouting.

Operation outside the memo-

rised area

When the vehicle leaves the memorised area, the
functions will be limited.
• The auto reroute function does not work.
• You can only display a larger scale map. The

map display will automatically change to a 50-
km (or 100-km) scale.

• The map matching function will not be availa-

ble. Therefore, the position of your vehicle may
be misaligned.

• Only the navigation guidance when arriving to

your destination will be available; no other
guidance is possible (this includes no display
of direction arrows).

To cancel these limitations, reset the DVD Map
Disc to the navigation system.

Positioning Technology

The navigation system accurately measures your
current location by combining the positioning by
GPS and by Dead Reckoning.

Positioning by GPS

The Global Positioning System (GPS) uses a net-
work of satellites orbiting the Earth. Each of the
satellites, which orbit at a height of 21 000 km,
continually broadcasts radio signals giving time
and position information. This ensures that sig-
nals from at least three can be picked up from
any open area on the earth’s surface.
