7-10 Infotainment System Multi-Band Antenna Vehicles with OnStar have a multi-band antenna located on the roof of the vehicle. The antenna is used for the AM/FM radio, OnStar and the XM Satellite Radio Service System. Keep the antenna clear of obstructions for clear reception. If the vehicle has a sunroof, the performance of the AM/FM radio, OnStar, and the XM system may be affected if the sunroof is open. Audio Players CD Player Care of the CD Player Do not add labels to a CD. It could get caught in the CD player. Use a marking pen to write on the top of the CD if a description is needed. Do not use CD lens cleaners, they could damage the CD player. Notice: If a label is added to a CD, or more than one CD is inserted into the slot at a time, or an attempt is made to play scratched or damaged CDs, the CD player could be damaged. While 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 displays, see "CD Messages" earlier in this section. Care of CDs 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 or CD-RW has been handled. Handle them carefully. Store CD-Rs 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. 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. If the surface of a CD is soiled, clean it with a soft, lint‐free cloth or dampen a clean, soft cloth in a mild, neutral detergent solution mixed with water. Make sure the wiping process starts from the center to the edge.
