137 Controls in detail
Automatic climate control
Automatic mode
Switching on
Briefly press buttonU
(page 135).
The indicator lamp comes on. The tem-
perature, air volume and distribution
are controlled automatically.
Adjust the temperature with the tem-
perature control4 (
page 135).
Temperature control is switched off in
the extreme position (blue or red dot).
Switching off
Briefly press buttonU
(page 135).
The indicator lamp goes out. The auto-
matic mode is switched off.
Air volume control1 is set to fan
speed 2 and air distribution is set
toV.Activating basic setting
Press buttonU at least
three seconds.
All functions are switched to automatic
mode and temperature is set to 72°F
(22°C).
Changing basic setting
Set temperature control4
(page 135) to desired temperature.
Press buttonU for ten seconds.
The selected temperature value is
stored and set.Adjusting air volume and air distribu-
tion manually
Adjusting air volume
Turn air volume control1 to one of
five air volume settings.
iAdjust temperature settings in small
increments.
iIf you turn air volume control1 or air
distribution control8 (
page 135),
the automatic mode switches off. The
indicator lamp in the buttonU goes
out. The temperature control will still
be in automatic mode.
iWhen set to 0 the system is fully deac-
tivated and no fresh air is supplied. This
setting should only be selected for
short periods of time.

Fig. 6: Identifying Fiber Optic Cable Components Location
FIBER OPTIC CABLE, FUNCTION - GF82.00-P-4000-04A
The fiber optical cable consists of plastic with a fiber diameter of 1 mm. Each fiber optical cable is protected
against mechanical damage and against admission of outside light with the help of an orange-colored insulation.
The light for the data transfer in the digital data bus (D2B) has a wavelength of 650 nm; by comparison, visible
light lies in the range of blue with 400 nm to red with 800 nm. Optical attenuation of the light signal can occur
in the fiber optic cable. Attenuation of the optical signal in the fiber optical cable is dependent on:
the length of the line between the individual components
the bending radii when routing the fiber optical cable, which must have min. bending radius = 25 mm
the condition of the insulation of the fiber optical cable
A passive connector; this is used when a component is removed from the digital data bus (D2B) due to a
fault.
To ensure the functional availability of the remaining components, the digital data bus (D2B) is closed again
using a passive connector. The fiber optical cable has two different connection ends:
The fiber optical cable input, which is the output to each control unit. This is marked in "white".
The fiber optical cable output, which is the input to each control unit. This is marked in "red".

DVD drive and DVD
The DVD drive of the radio (A2) reads data from the navigation DVD inserted and makes this available to the
navigation processor via the data bus inside the device.
Audio CDs can also be played.
The following are located on the navigation DVD:
Program data for the navigation computer
Voice segments for voice output
Map data.
A distinction is made between digitized and non-digitized areas within the DVD map area:
Villages, towns, roads, intersections and their attributes (e.g. one-way streets, no turns etc.) are recorded
in the digitized map area.
Included in the non-digitized areas are, for example company/private grounds, farms, small housing
estates, tracks across fields and areas between villages.
No data is available here.
Diagnosis interface (K-line) and fault management of D2B-components
During operation, the system stores all occurring faults in the nonvolatile memory. It is not possible to output
the fault via the display of the radio (A2).
The radio's (A2) fault management also includes the D2B-components connected. For this purpose, each D2B
component has its own DTC memory. The faults are transmitted from the corresponding components via the
D2B to the radio (A2) and can then be read out via the diagnosis interface
RADIO AND NAVIGATION MODULE, FUNCTION - GF82.61-P-4109-04GI
Processing button actuations
The control buttons and switches on the function keypad on the radio and navigation module (A2/56)are read
in via the I/O ports of the microcontroller and transferred to the central processor. Depending on the system
function the button actuations are processed in the central processor or relayed to the other system components
via the digital data bus ( D2B ) in form of a data telegram.
Graphic preparation and image output
The graphics subsystem handles the preparation and output of the operating displays. The operating displays are
output internally to the display by the graphic subsystem via the RGB output ( R =red, G =green, B =blue).
The RGB signal contains information and amplitudes of the three basic colors Red, G reen and Blue as well
