Notes on installation of GPS antenna
The GPS antenna should be installed only in a vertical position with a maximum deviation of 10° from
horizontal.
The GPS antenna should always have a free view of the sky. Thermal insulated windows can significantly
reduce the function of the GPS antenna.
When installing the GPS antenna, always ensure that the arched surface points away from the vehicle.
Changing the installation location inside of the vehicle after the system is put into operation has no effect on the
GPS reception.
NOTES ON RADIO CONNECTOR PIN ASSIGNMENT - AH82.61-P-0001-05A
Model 163
The pin assignment in the radio connector has been changed on vehicles as of 07.99 (model year 2000)
Fig. 1: Identifying Radio Connector Pin Assignment

Check pin assignment
If the pin assignment is the same as listed in the table above, it is not necessary to install the adapter
wiring harness and CAN bus adapter when installing the Audio 30 APS navigation system.

Vehicles with telephone code 316 or 317 can be retrofitted with an Audio 30 APS navigation system.
Ensure that the Audio 30 APS navigation system is a unit with part number A 208 820.....Older units with part
number A 168 820 .. .. are not capable of assuming the master function in the D2B- ring.

The Audio 30 APS does not have a number pad. For this reason, it is not possible to control the telephone over
the radio (see operating instructions).
On vehicles (as of approx. 07.99) with multifunction steering wheel (telephone control with keys on steering
wheel) this function is then also possible with the Audio 30 APS navigation system.

Customer information, installation position for GPS antenna
There are two different installation locations for the GSP antenna:
1. Standard GPS antenna from DaimlerChrysler on roof or trunk lid. This version offers the best reception
and is therefore preferable.
2. Use of magnetic antenna in vehicle passenger compartment. This version is part of the kit from the
Becker company and installation is described in Becker installation instructions.
Notes on installation of Becker GPS antenna
The GPS antenna can only be installed horizontally with a maximum deviation of 10° from horizontal.
The GPS antenna should always have an unobstructed view of the sky. Tinted windows can reduce the function
of the GPS antenna considerably.
When installing the GPS antenna always ensure that the arched surface of the antenna points upwards.

Position of the identification
For vehicle models 170, 202, 203, 208, 210, 215, 220, 230, 463 an identification plate is located on the fiber
optic cable wiring harness behind the radio on which the fiber optic cable modules (1, 2, 3, 4) specially fitted to
these vehicles are specified together with their exact length.
With models 129, 414 the identification plate is in the trunk next to the CD changer.
With model 168, the identification plate is in the passenger footwell in the area of the control unit box. If there
is no length specification on the identification plate, the respective fiber optic cable module must be removed
and the necessary length measured.
Vehicle model 163 does not have any identification plate.
With repairs, the individual fiber optic cable modules with corresponding length specification can be ordered
(see spare-parts documentation Group 82).

Routing
The inserts (5) of the fiber optic cable modules may only be routed as in production. The fiber optic cable
modules must always be pr ovided with a protective cap when routing. For every vehicle model, the sequence of
components in the D2B ring is specifically predetermi ned. The components are connected by fiber optic cable
modules. They are secured to a wiring ha rness with an orange-colored casing.
Fig. 4: Identifying Fiber Optic Cable Modules Insert

Danger of breaking! Do not kink fiber optic cable, route over sharp edges or be nd in radii smaller than 25
mm. Tensile forces on inserts must not exceed 65 N.
The fiber optic cable must not be exposed to temperat ures greater than 85°C or lower than -40°C. Do not
squeeze fiber optic cable, in other words do not compress with clamps or cable ties.
Connection between the devices
The Digital Data Bus ring (D2B) connects the new ra dio generation and COMAND (monitor) to the CD
changer (CDC) (USA preinstallati on), telephone and portable CTEL. The sound amplifier remains wired as
COMAND (monitor) to the CD changer (CDC) (USA preinstallation), telephone and portable CTEL. The sound
amplifier remains wired as befo re with Models 129, 170, 202, 208 and 210. The radio and COMAND as head
unit (HU) performs the master function and also forms the interface to the Control Area Network bus Class B
(interior) (CAN-B) (for vehicles wi th multifunction steering wheel).

Fig. 5: Identifying Digital Data Bus (D2B), Function
Digital Data Bus (D2B)
The Digital Data Bus (D2B) is a data transmission system for the communication and information components,
which utilizes the optical data transfer options. Data transfer is conducted by means of optical pulses, which are
transferred over fiber optical cables to the connected communication and information components. Audio and
command signals are converted in the source components into optical pulses and transmitted via fiber optical
cables. The optical signal is converted back to an electronic signal in the target component. Because of the high
transfer rate, the Digital Data Bus (D2B) can transfer audio and command signals simultaneously. Simultaneous
transfer of source data and command data over the Digital Data Bus (D2B) significantly reduces the amount of
cabling. The connected components require 2 lines for the voltage supply (electrical) and 2 lines (input/output)
for the fiber optical cable of the Digital Data Bus (D2B) and one line for the wake-up signal (electrical).
In addition to this the fiber optical cable can transfer several pieces of source data simultaneously (e.g. music
and voice from 2 components), without compromising the data content.
Functional sequence on example of "Play CD" on model 220
Pressing "Play" on the radio (A2) sends a command signal over the Digital Data Bus (D2B) to the CD player
with changer (in trunk) (A2/6), for vehicles with code (819) 6-disc CD changer. The audio signals from the CD
player with changer (in the trunk) (A2/6), for vehicles with code (819) 6-disc CD changer, are then sent over the
Digital Data Bus(D2B) as source data to the Sound amplifier (A2/13), or for vehicles with code (810) to the
sound system. The target components, the Sound amplifier (A2/13), or for vehicles with code (810) the sound
system, the source data are then converted back to electrical signals and reproduced as sound.
Data transfer using fiber optic cables has the following advantages:
Extremely high data transmission rate
Prevents tapping and cross talk
Insensitive to electromagnetic radiation
