7-18 AM Infotainment System Cellular Phone Usage Cellular phone usage can cause interference with the vehicle's radio. Audio Players CD/DVD Player The player can be used for CD, MP3, and DVD audio, and as a DVD video player. With the vehicle on, insert a CD/DVD into the slot, label side up. The player pulls it in and begins playing. While playing, the navigation system is available. The vehicle must be in P (Park) for video to display. The DVD player is only compatible with DVDs of the appropriate region code printed on the jacket of most DVDs. 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. Static can occur when things like storms and power lines interfere with radio reception. When this happens, try reducing the treble on the radio. Multi-Band Antenna The multi-band antenna is on the roof of the vehicle. The antenna is used for the AM‐FM radio, OnStar, the XM Satellite Radio Service System, and GPS (Global Positioning System), if the vehicle has these features. Keep the antenna clear of obstructions for clear reception. 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 may cause loss of the XM signal for a period of time.
