Using the Auxiliary Input Jack
AUX IN (Auxiliary Input): The radio system has an
auxiliary input jack located on the lower right side of
the faceplate. This is not an audio output. Do not plug
the headphone set into the front auxiliary input jack.
An external audio device such as an iPod, laptop
computer, MP3 player, CD changer, or XM™ receiver,
etc. can be connected to the auxiliary input jack for
use as another source for audio listening.
The auxiliary input jack also accepts cell phone
connectors. Plug the cell phone connector into the
auxiliary input jack to hear a person speck on a
cell phone during a conversation through the vehicle
sound system.
Drivers are encouraged to set up any auxiliary device
while the vehicle is in PARK (P). See Defensive Driving
on page 4-2 for more information on driver distraction.
To use a portable audio player, connect a 3.5 mm
(1/8 inch) cable to the radio's front auxiliary input jack.
While a device is connected, turn the portable audio
player on and press the radio CD/AUX button to
hear audio from the device over the vehicle speakers.
O (Power/Volume): Turn this knob clockwise or
counterclockwise to increase or decrease the volume of
the portable player. Additional adjustments on a portable
device might be needed to get the desired volume.
CD/AUX (CD/Auxiliary): Press this button once to play
a CD while a portable audio device is playing. Press
this button a second time for the system to begin playing
audio from the connected portable audio player. Once
in this mode, Auxinput displays. If the auxiliary jack does
not detect the presence of an output jack, the auxiliary
mode does not display.
