7-6 Infotainment System 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. Radio Reception Frequency interference and static can occur during normal radio reception if items such as cell phone chargers, vehicle convenience accessories, and external electronic devices are plugged into the accessory power outlet. If there is interference or static, unplug the item from the accessory power outlet. Fixed Mast Antenna The multi-band antenna is on the roof of the vehicle. The antenna is used for AM, FM, and navigation System, if equipped. Tall buildings, hills, trees, heavy foliage, tunnels, bridges, and garages will affect reception. Keep the antenna clear of obstructions for clear reception. Make sure there is sufficient clearance when entering garages or parking structures. 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. AM 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. For better radio reception, most AM radio stations 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.
