Telematics.

Telematics services such as BMW Assist and BMW Online give you the information you want, when you want it. They provide you with information about your route, your destination and other useful travel facts.

Telematics is the combination of information and communications technology to send and receive data via telecommunications devices. It is used chiefly in Internet, telephone and mobile communication services as well as in vehicle telematics. Vehicle telematics can assist the driver in a wide range of situations and deliver useful information directly to the vehicle.
The BMW telematics services - BMW Assist, BMW Online and BMW TeleServices - intelligently combine the BMW navigation system with the in-car telephone and are designed primarily to improve your safety and mobility. BMW Assist for instance not only delivers a wide range of tailored information straight to your vehicle, but also provides up-to-date, location-based traffic news. It sends data gathered by roadside sensors to your BMW using GPS technology, enabling your navigation system to calculate a route that avoids traffic jams.
BMW TeleServices meanwhile monitors the condition of key wearing parts and, if required, even contacts your BMW Service Centre automatically to arrange a service.
