GMC 2009 Sierra - Manual (Page 243)

BAND: Press this button to listen to the radio when a
CD or a DVD is playing. The CD or DVD remains inside
the radio for future listening or viewing entertainment.
DVD/CD AUX (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 (RSE) System on page 3-109
for more information.
If a MP3/WMA is inserted into top DVD slot, the rear
seat operator can turn on the video screen and use the
remote control to navigate the CD (tracks only)
through the remote control.
