How vehicle audio works
FM reception
AM and FM radio signals are broad-
cast from transmitter towers located
around your city. They are intercept-
ed by the radio antenna on your vehi-
cle. This signal is then received by
the radio and sent to your vehicle
speakers.
When a strong radio signal has
reached your vehicle, the precise
engineering of your audio system
ensures the best possible quality
reproduction. However, in some
cases the signal coming to your vehi-
cle may not be strong and clear.
This can be due to factors, such as
the distance from the radio station,
closeness of other strong radio sta-
tions or the presence of buildings,
bridges or other large obstructions in
the area.

Features of your vehicle
AM (MW, LW) reception
AM broadcasts can be received at
greater distances than FM broad-
casts. This is because AM radio
waves are transmitted at low fre-
quencies. These long, low frequency
radio waves can follow the curvature
of the earth rather than travelling
straight out into the atmosphere. In
addition, they curve around obstruc-
tions so that they can provide better
signal coverage.
