Radio Reception; Fixed Mast Antenna - Chevrolet 2015 City Express Owner's Manual

7-6 Infotainment System

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.
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.
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.

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.
