Using the Auxiliary Input Jack
Your 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. You can however, connect an
external audio device such as an iPod, laptop computer,
MP3 player, CD changer, or cassette tape player, etc.
to the auxiliary input jack for use as another source for
audio listening.
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
car speakers.

counterclockwise to increase or decrease the volume of
the portable player. You may need to do additional
volume adjustments from the portable device if

Navigation/Radio System
Your vehicle may have a navigation radio system.
The navigation system has built-in features intended to
minimize driver distraction. Technology alone, no
matter how advanced, can never replace your own
judgment. See the navigation system manual for some
tips to help you reduce distractions while driving.

vehicle for the rst time.
If THEFTLOCK

if stolen. The radio will display LOCKED. If this occurs,
the radio will need to be returned to your GM dealer.
