station frequencies to interfere with
each other. Static can also occur when
things like storms and power lines
interfere with radio reception. When
this happens, try reducing the treble
on the radio.
Digital Audio Broadcasting (DAB)
If equipped, Digital Audio
Broadcasting (DAB) is a universal
broadcast system that indicates
stations by the radio program name
on the infotainment display. The DAB
signal produces a constant volume
and is not affected by interference
from nearby frequencies. The
reception quality of DAB improves if
the signal is reflected by natural
obstacles or buildings. If the DAB
signal is unclear, reception is
interrupted completely.
Mobile Phone Usage
Mobile phone usage, such as making
or receiving phone calls, charging,
or just having the phone on may
cause static interference in the radio.
Unplug the phone or turn it off if this
happens.

Multi-Band Antenna

The roof antenna may be used for
radio, navigation, and OnStar,
depending on the equipped options.
Keep clear of obstructions for clear
reception. If the vehicle has a sunroof,
and it is open, reception can also be
affected.

Avoiding Untrusted Media

Devices

When using media devices such as SD
cards, USB devices, and mobile
devices, consider the source.
Untrusted media devices could
contain files that affect system
operation or performance. Avoid use if
the content or origin cannot be
trusted.

USB Port

Audio stored on a USB device may be
listened to.
The vehicle may be equipped with two
USB ports in the center console under
the armrest. These ports are for data
and charging. There may also be two
USB ports for charging only at the rear
of the center console.
Caution
To avoid vehicle damage, unplug all
accessories and disconnect all
accessory cables from the vehicle
when not in use. Accessory cables
left plugged into the vehicle,
unconnected to a device, could be
damaged or cause an electrical
short if the unconnected end comes
in contact with liquids or another
power source such as the accessory
power outlet.
Playing from a USB
A USB mass storage device can be
connected to the USB port.
Audio extensions supported by the
USB may include:
MP3
AAC
OGG
3GP
