Cellular phone Radio reception
Mobile communications systems (cellu-
lar phone, radio, etc.) are permitted with
an output up to 10 watts only. Even
these systems may trigger malfunctions
in the operation of your vehicle if they
are not specifically designed for use
with the vehicle. BMW can neither test
nor assume responsibility for every indi-
vidual product being offered on the
market. We recommend that you con-
sult your BMW center before purchas-
ing any device of this kind.
To ensure that your BMW continues to
provide reliable and trouble-free opera-
tion, refrain from using a cellular phone
or other radio device with an antenna
located inside the passenger compart-
ment. The antenna should always be
mounted on the outside of the vehicle.
Before loading the vehicle on a
car-carrier train or driving it
through a car-wash, remove the an-
tenna.<
The reception and sound quality ob-
tained from mobile radios varies ac-
cording to a variety of factors, including
the broadcast range of the transmitter
and the directional orientation of the
antenna. Interference factors such as
high-tension power lines, buildings and
natural obstructions can all lead to un-
avoidable reception interference, re-
gardless of how well the vehicle sound
system is operating.
Climatic factors such as intense solar
radiation, fog, rain and snow can also
interfere with reception.
Cellular phones without official BMW
approval can also generate interfer-
ence. This phenomenon assumes the
form of a low-pitched hum emanating
from the speaker system.
Please refer to the supplementary oper-
ating instructions provided with your
sound system for detailed information
on its use.
