Infotainment System boost the power levels during the day, and then reduce these levels during the night. Static can also occur when things like storms and power lines interfere with radio reception. When this happens, try reducing the treble on the radio. 7-11 Fixed Mast Antenna (Multi-Band) The multi-band antenna is on the roof of the vehicle. The antenna is used for OnStar® and the SiriusXM® Satellite Radio Service System if the vehicle has these features. Keep the antenna clear of obstructions for clear reception. Make sure there is sufficient clearance when entering garages or parking structures. Fixed Mast Antenna (Care) The fixed mast antenna can withstand most car washes without being damaged as long as it is securely attached to the base. If the mast becomes slightly bent, straighten it out by hand. If the mast is badly bent, replace it. Make sure there is sufficient clearance when entering garages or parking structures. Occasionally check to make sure the antenna is tightened to its base. If tightening is required, tighten by hand. FM Stereo FM stereo gives the best sound, but FM signals reach only about 16 to 65 km (10 to 40 mi). Tall buildings or hills can interfere with FM signals, causing the sound to fade in and out. Cellular Phone Usage Cellular phone usage may cause interference with the 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.
