Multi-Band Antenna; Audio Players; Cd Player - GMC 2010 Terrain Owner's Manual

6-18 Infotainment System
AM
The range for most AM stations is
greater than for FM, especially at
night. The longer range can cause
station frequencies to interfere with
each other. Static can occur when
things like storms and power lines
interfere with radio reception. When
this happens, try reducing the treble
on the radio.
XM Satellite Radio Service
XM Satellite Radio Service gives
digital radio reception from
coast-to-coast in the 48 contiguous
United States, and in Canada. Just
as with FM, tall buildings or hills can
interfere with satellite radio signals,
causing the sound to fade in and
out. In addition, traveling or standing
under heavy foliage, bridges,
garages, or tunnels may cause loss
of the XM signal for a period of time.
Cellular Phone Usage
Cellular phone usage can cause
interference with the vehicle's radio.

Multi-Band Antenna

The multi-band antenna is located
on the roof of the vehicle. The
antenna is used for the AM/FM
radio, OnStar, the XM Satellite
Radio Service System, and GPS
(Global Positioning System); if the
vehicle has these features. Keep
the antenna clear of obstructions for
clear reception. If the vehicle has a
sunroof and it is open, the
performance of the AM/FM radio,
OnStar, XM system, and GPS can
be affected.

Audio Players

CD Player

The CD player can play audio CDs
and MP3 CDs.
The CD player will not play
8 cm (3 in.) CDs.
Care of CDs
Sound quality can be reduced due
to disc quality, recording method,
quality of the music recorded, and
how the disc has been handled.
Handle discs carefully and store
them in their original cases or other
protective cases away from direct
sunlight and dust. If the bottom
surface of a disc is damaged, the
disc may not play properly or at all.
Do not touch the bottom surface of
a disc while handling it; this could
damage the surface. Pick up discs
by grasping the outer edges or the
edge of the hole and the outer edge.
