14 Navigation
Before Use
■Points to note before use
Starting the engine before using the system
The navigation system can be used with the ignition key in either the
ON position or the ACC position. To preserve the battery, however, it
should be used with the engine running whenever possible. Using
the system for a long time with the engine off can cause the battery
to run down.
Delay before display of current position
The system will not immediately display a correct indication of your
vehicle's current positio n after being switched on for the first time or
after the battery has been disconnected for a long time. It will display
a correct current position indication as soon as it receives Global Posi-
tioning System (GPS) signals.
Program reloading after battery disconnection
The navigation program will be erased from the system's memory if
the battery is disconnected. If th is happens, load the provided DVD-
ROM disc in the system's main unit and turn the ignition switch to
the ON or ACC position. The system will automatically reload the pro-
gram and start operating normally again.
Incorrect operation on rough roads
The system may operate incorrectly or be unable to read the data on
the DVD-ROM disc when subjected to severe vibration caused by
driving on rough roads.
Handling the GPS antenna
Do not paint the antenna. Doing so could impair or prevent signal
reception. Disabled switches
Some switches are disabled during operation of the system. These
switches are displayed in fainter colors and no messages are dis-
played for them.
Risk of damage to the main unit
Be mindful of the occupant compartment temperature. Using the
system when the occupant compar tment temperature is extremely
high or low can damage it or cause it to malfunction. Also, note that
the system's main unit can be da maged by strong vibration and by
any metallic object or water that gets inside.
Condensation
Condensation can form on the lens inside the main unit when there
is a rapid change in occupant co mpartment temperature (for exam-
ple, when the heater is switched on in cold weather). Such condensa-
tion can cause the system to operate abnormally. If you wait an hour
or so for the condensation to di sappear, the system should start
working normally again. If normal op eration is still not restored after
several hours, we recommend that you contact the nearest SUBARU
dealer.
Replacing the DVD-ROM disc
If you need to replace the DVD-ROM disc, make sure the replacement
disc is compatible with your system's main unit. Inserting an incom-
patible disc could damage the unit.
