This label is needed to activate the service. If this message is received when tuned to channel 0, there may be a receiver fault. Consult with your GM dealer.

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, see "Care of Your CDs" later in this section. If there is no apparent damage, try a known good CD. 3-87 Unknown Chk XMRcvr Playing a CD (Single CD Player) Insert a CD partway into the slot, label side up.
