The radio could begin playing while it is scanning the disc
in the background. When the scan is finished, the CD-R
or CD-RW begins playing again.
Once the disc has been scanned, the player defaults to
playing MP3/WMA files in order by artist. The current
artist playing is shown on the second line of the display
between the arrows. To listen to MP3/WMA files by
another artist, press the pushbutton located below either
arrow tab. Continue pressing either button until the
desired artist is displayed.
To change from playback by artist to playback by album,
press the pushbutton located below the Sort By tab. From
the sort screen, push one of the buttons below the album
button. Press the pushbutton below the back tab to return
to the main music navigator screen. The album name
displays on the second line between the arrows and
songs from the current album begins to play. Once all
songs from that album are played, the player moves to
the next album in alphabetical order on the CD-R/CD-RW
and begins playing MP3/WMA files from that album.
To exit music navigator mode, press the pushbutton
below the Back tab to return to normal MP3/WMA
playback.

BAND: Press 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 to cycle through
DVD, CD, or Auxiliary when listening to the radio.
The DVD/CD text tab 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 does 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 AUX, and Rear AUX
(if available). See "Using the Auxiliary Input Jack(s)" later
in this section, or Rear Seat Entertainment (RSE) System
on page 3-109 Rear Seat Entertainment System,
"Audio/Video (A/V) Jacks" 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.
