Cellular phone* Radio reception
Mobile communications systems (cellu-
lar phone, radio, etc.) are only allowed a
power output of up to 10 Watts. Mobile
communications devices not specifi-
cally designed for use in your vehicle
may trigger malfunctions during vehicle
operation. BMW can neither test nor
assume responsibility for every individ-
ual product being offered on the mar-
ket. We recommend that you consult
your BMW center before purchasing
any device of this kind.
To ensure that your BMW continues to
provide reliable and trouble-free opera-
tion, do not use a cellular phone or
other radio device with an antenna lo-
cated inside the passenger compart-
ment. The antenna should always be
mounted on the outside of the vehicle.
The reception and sound quality
obtained from mobile radios vary
according to a variety of factors, includ-
ing the broadcast range of the transmit-
ter 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 recep-
tion.
Cellular phones without formal 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 Owner's Manual
provided with your sound system for
detailed information on its use.
