BMW Bluetooth interface - the requirements.
The mobile phone preparation with Bluetooth interface is available for all BMW models. As the implementation of Bluetooth standards differs depending on the mobile phone and software version, new devices and software offers are continually being tested for compatibility.
An optional snap-in adapter can also be used to successfully operate the mobile phone with the Bluetooth interface using the vehicle’s external antenna connection. This feature also reduces cellular radiation within the vehicle, and will charge the handset.
