Root Directory
The root directory will be treated as a folder. If the root
directory has compressed audio files, the directory
will be displayed as ROOT. All files contained directly
under the root directory will be accessed prior to
any other directory.
Empty Directory or Folder
If a root directory or a folder exists somewhere in the
file structure that contains only folders/subfolders and no
compressed files directly beneath them, the player will
advance to the next folder in the file structure that
contains compressed audio files and the empty folder
will not be displayed or numbered.
No Folder
When the CD contains only compressed files, the files will
be located under the root folder. The next and previous
folder functions will have no function on a CD that was
recorded without folders or playlists. When displaying the
name of the folder the radio will display ROOT.
When the CD contains only compressed audio files, but
no folders, all files will be located under the root
folder. When the radio displays the name of the folder,
the radio will display ROOT.
Order of Play
Tracks will be played in the following order:
•Playback will begin from the first track under the
root directory.
•When all tracks from the root directory have been
played, playback will continue from files, according
to their numerical listing.
•After playing the last track from the last folder, the
player will begin playing again at the first track of
the first folder or root directory.
File System and Naming
The song name in the ID3 tag will be displayed. If the
song name is not present in the ID3 tag, then the
radio will display the file name without the extension
(such as MP3/WMA) instead.
Track names longer than 32 characters or 4 pages will
be shortened. The display will not show parts of
words on the last page of text and the extension of the
filename will not be displayed.
3-67

Playing an MP3/WMA
With the ignition on, insert a CD partway into the slot,
label side up. The player will pull it in, Loading, then
Filecheck, and then MP3 or WMA will appear on
the display. The CD should begin playing. You cannot
insert a CD with the ACC off.
As each new track starts to play, the track number, and
the song name will appear on the display.
If the ignition or radio is turned off with a CD in the player,
it will stay in the player. When a CD is in the player and
the ignition is turned on, the radio must be turned on
before the CD will start playback. When the ignition and
radio are turned on, the CD will start playing where it
stopped, if it was the last selected audio source.
The CD player can play the smaller 3 inch (8 cm) single
CDs with an adapter ring. Full-size CDs and the
smaller CDs are loaded in the same manner.
If playing a CD-R, the sound quality may be reduced due
to CD-R quality, the method of recording, the quality of
the music that has been recorded, and the way the CD-R
has been handled. There may be an increase in skipping,
difficulty in finding tracks, and/or difficulty in loading and
ejecting. If these problems occur, check the bottom
surface of the CD. If the surface of the CD is damaged,
such as cracked, broken, or scratched, the CD will not
play properly. If the surface of the CD is soiled, seeCare
of Your CDs on page 3-71for more information.If there is no apparent damage, try a known good CD.
Do not add any label to a CD, it could get caught in the
CD player. If a CD is recorded on a personal computer
and a description label is needed, try labeling the top of
the recorded CD with a marking pen instead.
Notice:If you add any label to a CD, insert more
than one CD into the slot at a time, or attempt
to play scratched or damaged CDs, you could
damage the CD player. When using the CD player,
use only CDs in good condition without any
label, load one CD at a time, and keep the CD player
and the loading slot free of foreign materials,
liquids, and debris.
If an error appears on the display, see “CD Messages”
later in this section.
All of the CD functions work the same while playing an
MP3WMA, except for those listed here. See “Playing
a CD” earlier for more information.

CD Messages
CHECK CD:If this message appears on the display
and/or the CD comes out, it could be for one of the
following reasons:
•It is very hot. When the temperature returns to
normal, the CD should play.
•You are driving on a very rough road. When the
road becomes smoother, the CD should play.
•The CD is dirty, scratched, wet, or upside down.
•The air is very humid. If so, wait about an hour and
try again.
•The format of the CD may not be compatible. See
“MP3 Format” earlier in this section.
•There may have been a problem while burning
the CD.
•The label may be caught in the CD player.
If the CD is not playing correctly, for any other reason,
try a known good CD.
If any error occurs repeatedly or if an error cannot be
corrected, contact your dealer. If the radio displays
an error message, write it down and provide it to your
dealer when reporting the problem.

Using the Auxiliary Input Jack
Your radio system has an auxiliary input jack located on
the lower right side of the faceplate. This is not an
audio output; do not plug the headphone set into the
front auxiliary input jack. You can however, connect an
external audio device such as an iPod, laptop
computer, MP3 player, CD changer, or cassette tape
player, etc. to the auxiliary input jack for use as another
source for audio listening.
The auxiliary input jack will also accept cell phone
connectors. Plug the cell phone connector into
the auxiliary input jack to hear the other side of a cell
phone’s conversation through the vehicle sound system.
To use a portable audio player, connect a 3.5 mm
(1/8 inch) cable to the radio’s front auxiliary input jack.
When a device is connected, press the radio CD/AUX
button as needed to begin playing audio from the device
over the car speakers.
CD/AUX (CD/Auxiliary):Press this button once to play
a CD while a portable audio device is playing. Press
this button a second time for the system will begin
playing audio from the connected portable audio player.
Once in this mode, “Auxinput” will appear on display.
If the auxiliary jack does not detect the presence of an
output jack, the aux mode will be prevented from
coming up.
O(Power/Volume):Turn this knob clockwise or
counterclockwise to increase or decrease the volume of
the portable player. You may need to do additional
volume adjustments from the portable device if
the volume does not go loud or soft enough.
Radio Reception
You may experience frequency interference and static
during normal radio reception if items such as cellphone
chargers, vehicle convenience accessories, and
external electronic devices are plugged into the
accessory power outlet. If there is interference or static,
unplug the item from the accessory power outlet.
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. For
better radio reception, most AM radio stations will boost
the power levels during the day, and then reduce
these levels during the night. Static can also occur when
things like storms and power lines interfere with radio
reception. When this happens, try reducing the treble on
your radio.
