Retrofit optical waveguide cable harness - AN82.70-P-0002-01AM

Depicted with sound amplifier (A2/13) and CD changer (A2/6) special equipment 

Subscriber sequence before  installation:

• Radio (A2) or  COMAND operating, display and control module (A40/3)
• • a. Sound amplifier (A2/13) or CD changer (A2/6)
  • b. Sound amplifier (A2/13) and CD changer (A2/6)
• Radio (A2) or  COMAND operating, display and control module (A40/3)

Depicted with sound amplifier (A2/13) and CD changer (A2/6) special equipment 

Subscriber sequence after  installation (must be complied with):

• Radio (A2) or  COMAND operating, display and control module (A40/3)
• Sound amplifier (A2/13)
• CD changer (A2/6)
• Telephone transmitter/receiver D2B (A35/13)
• Radio (A2) or  COMAND operating, display and control module (A40/3)

  Optical waveguides are given new consecutive numbers after installation of a new ring subscriber (note information flow).

Vehicles without sound amplifier (code 810) are converted in identical manner. In this case there is no M2 module.

1. Unplug connector housing of CD changer (A2/6).
2. Release connector housing and withdraw white insert (ws) from connector housing for CD changer (A2/6).
3. Insert new optical waveguide module M3 (new) together with white insert (ws) into the connector housing for the CD changer (A2/6), lock the housing and connect again.

   Observe special routing guidelines for optical waveguides.

4. Remove white (ws) insert of present M3 optical waveguide module from connector on CD changer (A2/6) and insert into new connector housing. Optical waveguide module M4 is thus created.
5. Insert new M3 optical waveguide module with red (rt) insert into new connector housing and lock housing

   The M3 optical waveguide module should be just long enough to establish a connection to the CD changer (A2/6) with the CTEL transmitter/receiver D2B (A35/13).

   Observe special routing guidelines for optical waveguides.

6. Route the closed new connector to the CTEL transmitter/ receiver D2B (A35/13) along the existing lines.

   Route any excess lengths in the area of the device plate under the right rear seat in a loop that corresponds to the routing guidelines for optical waveguides.

7. Route optical waveguide (M3, new) along existing wiring harnesses (M1, old) from trunk to cable duct on rear panel and on to the left rear cable duct.

8. Route optical waveguide modules (M1, M3 and M4) as shown in figure into the cable ducts in the vehicle interior and fasten in place using adhesive felt.
