Infotainment 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. 6-37 Fixed Mast Antenna The AM-FM antenna is located on the roof of the vehicle. Driving through an automatic car wash without removing the antenna could damage it. To remove the antenna, turn it counterclockwise. To replace the antenna, turn it clockwise until hand tightened. Cellular Phone Usage Cellular phone usage may cause interference with the vehicle's radio. This interference may occur when making or receiving phone calls, charging the phone's battery, or simply having the phone on. This interference causes an increased level of static while listening to the radio. If static is received while listening to the radio, unplug the cellular phone and turn it off. XM™ Satellite Radio Antenna System The XM Satellite Radio antenna is located on the roof or the rear of the vehicle. Keep the antenna clear of obstructions for clear radio reception.
