In order to ensure the operational reliability of your vehicle, do not use radio telephones or other portable radio communication devices whose antenna is located inside the vehicle or is not secured to the outside of the vehicle.
Remove the antenna before loading into trucks or before passing through automatic car wash machines.
Radio reception
The quality of reception and reproduction of sound by a car radio depends on the distance of the radio station, as well as the position of the car during reception and the orientation of the antenna.
Despite the perfect protection against interference created by the vehicle's own systems, during reception while driving, unsuppressed extraneous noises occur due to external influences, the sources of which are high-voltage power lines, buildings or natural obstacles in the path of radio waves. Natural influences such as the intensity of solar radiation, fog, rain or snowfall can also interfere with radio reception.
Car or portable telephones not recommended by BMW may also cause interference. This interference manifests itself as a low-pitched hum from the loudspeakers.
Installation and handling of the radio receiver are described in the enclosed operating instructions.
