Permission to use mobile communication systems (car phone, walkie-talkie, etc.) power not more than 10 watts. However, such devices may interfere with the normal operation of your vehicle unless specifically designed for your vehicle. BMW cannot control all products of this kind and therefore cannot be held responsible for them. Before purchasing these systems, we recommend that you consult a BMW workshop.
To ensure the operational safety of your vehicle, do not use cordless telephones or other portable radio communication devices whose antenna is located inside the passenger compartment or is not attached to the outside of the vehicle.
Remove the antenna before loading onto road transport vehicles or before passing automatic washers.
