How vehicle audio works
FM reception
AM and FM radio siþnals are broadcast
ýrom transmitter towers located
around your city. They are intercepted
by the radio antenna on your vehicle.
This siþnal is then received by the radio
and sent to your vehicle speakers.
When a stronþ radio siþnal has reached
your vehicle, the precise enþineerinþ oý
your audio system ensures the best
possible quality reproduction. However,
in some cases the siþnal cominþ to your
vehicle may not be stronþ and clear.
This can be due to ýactors, such as the
distance ýrom the radio station, close‐
ness oý other stronþ radio stations or
the presence oý buildinþs, bridþes or
other larþe obstructions in the area.
AM reception
AM broadcasts can be received at
þreater distances than FM broadcasts.
This is because AM radio waves are
transmitted at low ýrequencies. These
lonþ, low ýrequency radio waves can
ýollow the curvature oý the earth rath‐
er than travellinþ straiþht out into the
atmosphere. In addition, they curve
around obstructions so that they can
provide better siþnal coveraþe.
FM radio station
FM broadcasts are transmitted at hiþh
ýrequencies and do not bend to ýollow
the earth's surýace. Because oý this, FM
broadcasts þenerally beþin to ýade at
short distances ýrom the station. Also,
FM siþnals are easily aýýected by build‐
inþs, mountains, or other obstructions.
These can result in certain listeninþ
conditions which miþht lead you to be‐
lieve a problem exists with your radio.
The ýollowinþ conditions are normal and
do not indicate radio trouble:
