WARNING: Driving while distracted
can result in loss of vehicle control, crash
and injury. We strongly recommend that
you use extreme caution when using any
device that may take your focus off the
road. Your primary responsibility is the
safe operation of your vehicle. We
recommend against the use of any
hand-held device while driving and
encourage the use of voice-operated
systems when possible. Make sure you
are aware of all applicable local laws
that may affect the use of electronic
devices while driving.
WARNING: Always place your
device in a secure location in your vehicle
so it does not become a projectile in a
sudden stop or crash. Failure to follow
this instruction could result in personal
injury.

The auxiliary input jack allows you to
connect and play music from your portable
music player through your vehicle speakers.
You can use any portable music player
designed for use with headphones. Your
audio extension cable must have male
connectors at each end.

with the audio unit and the portable
music player switched off.
2. Plug the extension cable from the
device into the audio input jack.
3. Switch on the radio and select either a
tuned FM station or a CD.
4. Adjust the volume as desired.
5. Switch on your device and adjust the
volume to half the maximum level.
6. Press AUX until LINE or LINE IN

unit, while your device remains connected.
Note:The audio extension cable must be
long enough for you to safely store the
device when your vehicle is moving.
Note:For optimum performance when
