GMC 2007 Acadia - Manual (Page 295)

O (Power/Volume): Turn this knob clockwise or
counterclockwise to increase or decrease the
volume of the portable player. You might need
to do additional volume adjustments from
the portable device if the volume does not go
loud or soft enough.
BAND: Press this button 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.
DVD/CD AUX (CD/Auxiliary): Press this button
to cycle through DVD, CD, or Auxiliary when
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 this
button 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 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
Auxiliary, and Rear Auxiliary (if available).
See “Using the Auxiliary Input Jack(s)” later in this
section, or “Audio/Video (A/V) Jacks” under,
Rear Seat Entertainment System on page 311 for
more information.
Using an MP3 (Radio with CD or
Six-Disc CD Player)
MP3/WMA CD-R or CD-RW Disc
The radio plays MP3/WMA files that were recorded
on a CD-R or CD-RW disc. The files can be
recorded with the following fixed bit rates: 32 kbps,
40 kbps, 56 kbps, 64 kbps, 80 kbps, 96 kbps,
112 kbps, 128 kbps, 160 kbps, 192 kbps,
224 kbps, 256 kbps, and 320 kbps or a variable
bit rate. Song title, artist name, and album
are available for display by the radio when
recorded using ID3 tags version 1 and 2.
Compressed Audio
The radio also plays discs that contain both
uncompressed CD audio (.CDA files) and
MP3/WMA files. By default the radio shows the
MP3 label on the left side of the screen but
plays both file formats in the order in which
they were recorded to the disc.
