from these stations and only works when the
information is available. While the radio is tuned to
an FM-RDS station, the station name or call letters
display. In rare cases, a radio station could
broadcast incorrect information that causes the
radio features to work improperly. If this happens,
contact the radio station.

Playing a CD (In Either the DVD or
CD Slot)
Insert a CD partway into the slot, label side up.
The player pulls it in and the CD should begin
playing (loading a disc into the system, depending
on media type and format ranges from
5 to 20 seconds for a CD, and up to 30 seconds
for a DVD to begin playing).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. The DVD/CD decks, (upper
slot is the DVD deck and the lower slot is the
CD deck) of the radio are compatible with most
audio CDs, CD-R, CD-RW, and MP3s.
When a CD is inserted, the text label DVD or CD
symbol appears on the left side of the radio
display. As each new track starts to play, the track
number appears on the display.
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 can 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 can be an increase in skipping,
difficulty in nding tracks, and/or difficulty in loading
and ejecting. If these problems occur, check the
bottom surface of the CD.

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
boosts 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.
FM Stereo
FM stereo gives the best sound, but FM signals
only reach about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals,
causing the sound to fade in and out.
XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada. Just as with FM,
tall buildings or hills can interfere with satellite
radio signals, causing the sound to fade in and out.In addition, traveling or standing under heavy
foliage, bridges, garages, or tunnels could cause
loss of the XM™ signal for a period of time.
The radio might display NO XM SIGNAL to
indicate interference.
Care of Your CDs and DVDs
Handle CDs carefully. Store them in their original
cases or other protective cases and away from
direct sunlight and dust. The CD player scans the
bottom surface of the disc. If the surface of a
CD is damaged, such as cracked, broken,
or scratched, the CD does not play properly or not
at all. If the surface of a CD is soiled, take a
soft, lint free cloth or dampen a clean, soft cloth in
a mild, neutral detergent solution mixed with
water, and clean it. Make sure the wiping process
starts from the center to the edge.
Do not touch the bottom side of a CD while
handling it; this could damage the surface. Pick up
CDs by grasping the outer edges or the edge of
the hole and the outer edge.
