Radio reception

Usually, the problem with radio reception does not mean there
is a problem with your radio – it is just the normal result of
conditions outside the vehicle.
For example, nearby buildings and terrain can interfere with
FM reception. Power lines or telephone wires can interfere
with AM signals. And of course, radio signals have a limited
range, and the farther you are from a station, the weaker its
signal will be. In addition, reception conditions change
constantly as your vehicle moves.
Here are some common reception problems that probably do
not indicate a problem with your radio:

FM

Fading and drifting stations – Generally, the effective range
of FM is about 40 km (25 miles). Once outside this range, you
may notice fading and drifting, which increase with the
distance from the radio transmitter. They are often
accompanied by distortion.
Multi–path – FM signals are reflective, making it possible
for two signals to reach your antenna at the same time. If this
happens, the signals will cancel each other out, causing a
momentary flutter or loss of reception.
Static and fluttering – These occur when signals are blocked
by buildings, trees, or other large objects. Increasing the bass
level may reduce static and fluttering.
