Playing a CD If the ignition or radio is turned off with the CD in the player, it will stay in the player. When the ignition or the radio is 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. You may experience an increase in skipping, difficulty in finding tracks, and/or difficulty in loading and ejecting. If these problems occur try a known good CD. Do not add paper labels to CDs, they could get caught in the CD player. If an error appears on the display, see "CD Messages" later in this section.
