Playing a CD (in Either the
DVD or CD Slot)
If the ignition or radio is turned off
with a CD in the player, it stays in
the player. When the ignition or
radio is turned on, the CD starts
playing where it stopped, if it was
the last selected audio source. The
CD is controlled by the buttons on
the radio faceplate or by the RSA
unit. See Rear Seat Audio (RSA)
System on page 7 49 for more
information. The DVD/CD decks
(the upper slot is the DVD deck and
the lower slot is the CD deck) of the
radio are compatible with most
audio CDs, CD-Rs, CD-RWs,
and MP3s.
When a CD is inserted, the text tab
DVD or CD symbol displays on the
left side of the radio display. As
each new track starts to play, the
track number displays.
The CD player can play the smaller
8 cm (3 in) single CDs with an
adapter ring. Full-size CDs and the
smaller CDs are loaded in the same
manner.
DVD/CD AUX (Auxiliary): Press to
cycle through DVD, CD, or Auxiliary
when listening to the radio. The
DVD/CD text tab and a message
showing the track or chapter
number will display when a disc is in
either slot. Press the DVD/CD AUX
button again and the system
automatically searches for an
auxiliary input device; see Auxiliary
Devices on page 7 34 for more
information. 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 does
not indicate No Aux Input Device.
If a front auxiliary device is
connected, the DVD/CD AUX button
Infotainment System
cycles through all available options,
such as: DVD slot, CD slot, Front
Auxiliary, and Rear Auxiliary
(if available). See Using the
Auxiliary Input Jack in Auxiliary
Devices on page 7 34 or Audio/
Video (A/V) Jacks under Rear Seat
Entertainment (RSE) System on
page 7 39 for more information.
If a disc is inserted into the top DVD
slot, the rear seat operator can turn
