To use a portable audio player, connect a 3.5 mm
(1/8 inch) cable to the radio's front auxiliary input jack.
When a device is connected, press the radio CD/AUX
button to begin playing audio from the device over
the vehicle speakers.
O (Power/Volume): Turn clockwise or
counterclockwise to increase or decrease the volume
of the portable player. Additional volume adjustments
might need to be made from the portable device if
the volume does not go loud or soft enough.
BAND: Press to listen to the radio when a portable
audio device is playing. The portable audio device
continues playing, so you might want to stop it or
power it off.
CD/AUX (CD/Auxiliary): Press to play a CD when a
portable audio device is playing. Press again and
the system begins playing audio from the connected
portable audio player. If a portable audio player is
not connected, No Input Device Found or No Aux

DVD/CD AUX (CD/Auxiliary) (Radio with CD
and DVD): Press to cycle through DVD, CD, or
Auxiliary while listening to the radio. The DVD/CD
text label and a message showing track or chapter
number displays when a disc is in either slot. Press
again and the system automatically searches for
an auxiliary input device, such as a portable audio
player. If a portable audio player is not connected,
"No Aux Input Device" displays. If a disc is in both the
DVD slot and the CD slot the DVD/CD AUX button
cycles between the two sources and does not indicate
"No Aux Input Device". If a front auxiliary device is
connected, the DVD/CD AUX button cycles through all
available options, such as: DVD slot, CD slot, Front
AUX, and Rear AUX (if available). See "Using the
Auxiliary Input Jack(s)" later in this section, or Rear
Seat Entertainment (RSE) System on page 3-99,
"Audio/Video (A/V) Jacks" for more information.
