BMW 7 Series: Introduction
The BMW Night Vision system provides the driver with a black-and-white image of the driving environment ahead of the vehicle in the central information display (CID).
BMW Night Vision is a 100% passive system without active infrared illumination. Objects situated ahead of the vehicle are shown in varying degrees of brightness depending on the temperature of these objects. This enables the driver to detect in good time heat-emitting objects such as people, animals, and other vehicles.
This thermal image is recorded with a Far Infrared camera (FIR) via a special imaging sensor which detects the infrared radiation in a specific wavelength range.
The BMW system is distinguished from infrared systems with active illumination by its resistance to dazzling, its long range, and its clearly structured image.

The system offers the following advantages:
- Improved vision in conditions of dusk and darkness
- No dazzling by the headlights of oncoming vehicles
- Highlighting of unilluminated, heat-emitting objects such as pedestrians, cyclists vehicles and deer, etc.
- Better overview of the driving situation thanks to the depiction of the route of the road beyond the headlight cone
- Enlarged depiction thanks to the zoom function of objects in the far distance at high speeds
- Illumination of bends/curves thanks to the bend/curve mode (pivoting of image detail)
- Illumination of dark courtyard and garage entrances
NOTE: The driving speed must be adapted to the relevant visibility conditions in each case. BMW Night Vision is designed as a supporting system, which, with a modified driving style, affords the driver an early, better overview of the road conditions ahead of the vehicle.

Principles Of Operation
The BMW Night Vision camera is a thermal imaging camera, which converts
thermal radiation into electronic
signals and then into images visible to the human eye.
The thermal image is converted first

Massage Function In Rear-Compartment Comfort Seat
The optional rear-compartment massage gives the rear-seat passenger even more
comfort than in the E65. The rear-compartment massage function is being offered
in the F01/F02 for the first time at BMW.
An electropneumatic system is used to implement the massage function.

USB/Audio Interface
The "USB/audio interface" supports the playback of audio files stored on mass
storage devices with USB
connections such as USB sticks, MP3 players etc.
USB is a serial bus system that allows fast and simple connection of terminal
devices to computer systems.
