RADIO MODE, FUNCTION - GF82.60-P-2001B
MODELS 163, 168, 170, 203.0 /2 /7, 208, 209.3 /4, 210 with CODE (353) Audio 30 APS
The ultra-short wave (FM), medium wave (MW) and long wave (LW) high-frequency signals are received from
the radio antenna mounted on the vehicle. The music, voice and/or data signals are modulated upon the high-
frequency signals received. The high-frequency signals are forwarded by the radio antenna over a coaxial cable
to the radio receiver in the radio and navigation unit (A2/56). The radio receiver demodulates the high-
frequency signals, i.e. it separates the useful information from the high-frequency carrier signal. The
demodulated audio signals are amplified and converted to sound signals by the vehicle speakers. Possibilities
for radio station selection:
Direct frequency input
Manual station search
Automatic station search (the stations on a waveband are played for approx. 8 s)
Station selection from the memory (6 stations for each frequency range)
Radio Data System (RDS), function
Many radio stations, e.g. (FM) transmit in addition to the program additional information such as the station
name, type of program (e.g. pop, culture, etc.), traffic station identification and alarm messages. This
information is evaluated and shown on the radio and navigation unit (A2/56) display, provided that:
the "RDS" function is switched on
an RDS station is set and received.
When an RDS station is received with a traffic broadcast in the background the abbreviation "TP" (Traffic

Program) appears on the radio and navigation unit display (A2/56).
Even when the RDS function is deactivated, the traffic station recognition and station following function remain
in operation (if activated). RDS alarm messages are still issued. In this case, CD playback or radio reception is
automatically interrupted.
2-tuner technology function
If interference occurs to reception while driving, the system attempts to receive the selected station on an
alternative frequency with the aid of the second (integrated) receiver and switch over when reception is better.
Moreover, the second radio receiver automatically generates a list of the receivable FM stations after switch-on,
and this list is continuously updated during operation. The stations contained in the list can be called up sorted
in alphabetical order with the station search buttons.
The station list is only available when the "RDS" function is activated.
At certain times, some radio channel programs are subdivided into regional programs.
Since the system automatically switches to an alternative frequency in the event of reception interference, this
can lead to a change in the regional program (not the radio network). If this is not desired, the regional program
function can be activated in the menu "REG". Switchover to an alternative frequency is then accomplished only
within the regional program.
FM antenna diversity function (models 209.3/4)
The antenna diversity function undertakes a reception-specific switchover between the FM antennas on the rear
window for model 209.3 (FM antennas of windshield for model 209.4). The function runs automatically and is
executed by the window antenna amplifier module 1 (A2/71) for model 209.3 (left antenna amplifier module
(A2/64) for model 209.4).
The radio tuner of the radio and navigation unit (A2/56) only generates the intermediate frequency (ZF) signal,
which serves as a reference to change the FM antenna for the window antenna amplifier module 1 (A2/71) on
model 209.3 (for model 209.4 left antenna amplifier module (A2/64)).
RDS Diversity/2-receiver technology function
The system consists of 2 FM receivers, a radio receiver and a search receiver. After turning on the radio system,
the search receiver automatically generates a list of FM stations received, which is continually updated during
operation.
Data such as reception quality, programs and alternative frequencies are stored. The audio receiver can therefore
switch over inaudibly to an alternative frequency. The list appears in alphabetical order when the "FM station
list" is called up. The stations which are displayed can be activated by selecting and confirming.

Activating anti-theft alarm
During initial operation of the radio and navigation unit (A2/56) it is necessary to activate the anti-theft
alarm with the aid of the hand-held tester.
After activation has been accomplished, deactivation is no longer possible.
Only after activation is it necessary to enter a 5-digit code after interruption of the power supply. When entering
the code observe:
After the code has been entered incorrectly three times the message "Wait" appears. The radio and
navigation unit (A2/56) is then disabled for ten minutes. ?
Following the next three incorrect entries operation is not possible for ten minutes again. ?
Then after an additional 3 incorrect entries the unit is disabled for 1 hour in each case.
The waiting time expires only with the radio and navigation unit (A2/56) switched on.
Inserting and ejecting CD
CDs can be inserted and ejected (audio or navigation CD) in all operating states. After pressing the "eject
button" a CD already inserted is ejected by a motor. If the CD is not removed within approx. 14 seconds, it is
pulled back in automatically.
After inserting a CD it is necessary to push it a slight distance into the CD opening; it is then pulled in the rest
of the way automatically.
When a navigation CD is inserted the menu for entering destination is activated automatically. However,
this applies only when the system has previously requested that the navigation CD be inserted.
The eject button for the CD drive also functions when the radio and navigation unit (A2/56)is in the "code
wait state". This means that a CD can be removed in spite of the request to enter the anti-theft code.

Indicator and warning signals

Indicator lamps for left turn signal (A1e1) and right turn signal

(A1e2)
The signal in models 129, 140, 170, 202 comes from the

combination relay (turn signals with trailer coupling, rear

window defroster, wiper motor, anti-theft alarm system)

(N10/2), and in model 210 from the multifunction control

module (N10-1) or the driver's side signal acquisition and

actuation module (SAM) (N10/1).

In model 168 the entire turn signal control is located in the

instrument cluster (A1).

Brake fluid / parking brake warning lamp (A1e7)

The signal for the brake fluid comes direct from the brake fluid level switch (S11) (except model 163).

(The signal for the parking brake comes over CAN.)

When the reserve fuel level is reached, this lamp lights up and

goes out again only after refueling is detected. If the vehicle is

refueled with the ignition ON, refueling is detected only if at

least 7 liters of fuel are added.

See document: Terminal 61 and terminal 61e, charge indicator

lamp, exterior lamp failure, function

Seatbelt/backrest lock warning lamp (A1e9)

The seat belt warning lamp is only used in a few national

versions, and is actuated direct by a seat belt buckle switch
(normally closed contact). After engine start, the lamp flashes

for a short time (approx. 6 seconds).

In model 129 if this lamp fails to go out after flashing briefly, but

continues to shine constantly, then the seat backrest is not

locked.
