Safety Precautions
WARNING
•The main unit requires a 12 V DC power supply. The main
unit should not be installed in any vehicle which does not
have a 12 V power system with a ground-connected
negative side. An installation other than the one intended
may cause severe damage to the main unit, and electric
shock or serious injury to the users.
•Even when using the route guidance of the navigation
system, be sure to drive by following the actual traffic
regulations. If you drive by following only the route
guidance of the navigation system, you may violate the
actual traffic regulations and cause a traffic accident.
•To ensure safety, the driver should not operate the
navigation system while driving. Operating the navigation
system while driving may result in an accidental steering
wheel operation or otherwise cause an accident. Stop the
vehicle before operating the navigation system. Also, do not
watch the screen while driving. Because doing so is
dangerous and may be unlawful. Inattention to road
conditions ahead may result in an accident.
•The driver should not perform operations such as volume
adjustment while driving. Inattention to road conditions
ahead may result in an accident, so be sure to stop the
vehicle in a safe place before performing the operation.
•The driver should not change discs while driving.
Inattention to road conditions ahead may result in an
accident, so be sure to stop the vehicle in a safe place before
performing the operation.
•The driver should not perform operations such as adding a
location or setting the memory while driving. Inattention to
road conditions ahead may result in an accident, so be sure
to stop the vehicle in a safe place before performing the
operation.
•Before viewing a video, be sure to stop the vehicle in a safe
place and apply the parking brake. To ensure safety, videos
are not displayed during driving.
•To ensure safety, never operate a cell phone while driving.
•Do not let foreign objects enter the disc slot or SD memory
card slot. Doing so may result in a fire or electric shock.
•Do not disassemble or modify the unit. Doing so may result
in an accident, fire or electric shock.
•Do not let water or foreign objects enter the internal parts of
the unit. Doing so may result in smoke, fire or an electric
shock.
•Do not use the unit when it is malfunctioning, such as when
the screen is not lit or no sound comes out. Doing so may
result in an accident, fire or electric shock.

Introduction 9
Before Use
•Always replace fuses with fuses of the same specified
capacity (amperage). Using a fuse with a higher capacity
than the specification may result in a fire.
•If a foreign object or water enters the unit, smoke or a
strange odor may be emitted. If such an abnormality occurs,
stop using the unit immediately and contact your SUBARU
dealer. An accident, fire or electric shock may result if you
continue to use the unit under these conditions.
•In a thunderstorm, do not touch the antenna line or the unit.
Lightning may cause an electric shock.
•Do not park or stop in prohibited areas to use the unit.
•If direct sunlight shines into the vehicle, light may reflect off
the product. Be very careful while driving.
•Never use headphones or earphones while driving. Driving
while not being able to hear sounds from outside the vehicle
may result in a traffic accident.
CAUTION
•Although the unit can be used when the ignition switch is
set to either ON or ACC, to protect the battery, start the
engine before using the unit.
•Do not use the unit anywhere other than in a vehicle. Doing
so may result in an electric shock or other injury.
•While driving, keep the volume low enough for you to hear
outside sounds. Driving while not being able to hear sounds
from outside the vehicle may result in an accident.
•Be careful of the volume when turning on the power. If a
loud noise is emitted suddenly when you turn on the power,
it may damage your hearing.

operation will return after a short time.
•Immediately after turning on the heater when the temperature is low, dew
(water drops) may adhere to the lens of the CD reader (condensation). If this
happens, leaving the unit for about an hour should remove the condensation
and return the unit to normal operation. If the unit does not return to normal
operation even after several hours, contact your SUBARU dealer.
•When using the unit for the first time after purchase, or after the battery was
removed for a long time, the current position may not be displayed correctly.
Wait a short time until the GPS positioning corrects the displayed position.
•This device is precision-engineered equipment and the recorded data can be
lost as a result of static electricity, electrical noise, vibration, or other
influences. To protect the device against data loss, we recommend keeping a
separate record of the data that you record after purchase.
•Note that the following events are not covered by the warranty.
1. Corruption or loss of the data recorded on the “SD memory card” by the
purchaser resulting from failure, incorrect operation or malfunction of the
unit, or any problems associated with it, or due to the effects of electrical
noise or other influences.
2. Corruption or loss of the map data or basic program stored in the “SD
memory card” resulting from the incorrect use of the unit by the
purchaser or a third party.
3. Corruption or loss of data recorded on the “SD memory card” by the
purchaser resulting from the malfunction or repair of the unit.
* Note that by installing or using the unit, you are regarded as having
consented to the points above.
•The unit has been designed to withstand electrical noise from other
electronic devices. However, if an electronic device that emits strong noise is
used next to the unit, the unit may show malfunctions such as screen
interference or noise. If this happens, stop using the electronic device that
you think is causing the problem.
