Although numerous factors combine to
impose inherent limitations on the
reception quality available from mobile
radios, specially designed systems can
be employed to minimize their effects:
The "Radio Data System" (RDS) makes
sure that, for broadcast stations send-
ing on several frequencies, the radio
automatically tunes to the frequency
with the best reception quality.
The Diversity Antenna system employs
several FM antennas integrated within
the rear window. An integral processor
automatically selects the antenna with
the best FM reception quality at any
given time. The selection of the antenna
takes place within milliseconds, and is
therefore not noticed by the radio lis-
tener.
BMW seats are configured for your or-
thopedic well-being. The active seat is
an engineering enhancement of BMW's
seats, designed to ensure less fatigue
during extended trips while sitting with
little movement. The seat is no longer a
passive element between the road, the
running gear and the passenger. In-
stead, it creates minor and impercepti-
ble shifts in your weight by an active
change in the contour of the seat sur-
face. The basic seat position is not
changed as this occurs.
Fluid cushions are located below the
surface of the seat in the seat's uphol-
stery on the left and right. The fluid is
circulated slowly back and forth be-
tween the two cushions by means of a
pump. This causes a movement of the
spinal column which is virtually imper-

ceptible, resulting in an improved flow
of blood to the vertebral discs and the
muscles in the area of the spinal col-
umn. Vehicle occupants can experience
less muscle cramping, back pain in the
spine's lumbar region and fatigue. The
active seat thus provides a significant
contribution to your driving comfort and
safety.
