The Navigation System Professional features a sleek design and a superior range of services: The easy-to-use navigation system is perfectly integrated into the iDrive Controller and Control Display operation concepts. The system comprises the hands-free facility with USB interface and voice control, the radio BMW Professional with DVD drive, as well as a 20 GB memory for audio files. The most popular POIs (points of interest) are listed as a symbol (gas station, hotels, etc.) according to search frequency in the POI menu. A fixed, high-resolution 10.2" colour display with split-screen function guarantees optimal readability and clarity. Its intuitive operation is carried out using the iDrive Touch Controller, whose touch-sensitive surface allows the driver to easily enter destination addresses using their handwriting. Alternatively, the system can also be operated via direct menu control buttons, the eight functional bookmarks or voice control. Thanks to the three-dimensional map display including satellite images as a map background – with photo-realistic depictions of selected sights – navigation becomes an exciting visual experience.
