   Observe special routing guidelines for fiber optic cables.

4. Insert red (rt) insert from new (M1) fiber optical cable module into new connector housing on CD player with changer (A2/6). Insert white (ws) insert from new (M2) fiber optical cable module into new connector housing on CD player with changer (A2/6) and lock connector housing.

   The telephone interface (A34/4) (with code 852 complete portable CTEL preinstallation on dome or  code 854 MB portable CTEL) or  D2B telephone transmitter/receiver (A35/13) (with code 853) MB standard telephone or  TELE AID control unit (A35/8) (with code 855 TELE AID) can represent the next ring component and are called "next ring component" in the following.

5. Remove connector housing from next ring component and unlock.
6. Remove red (rt) insert from old (M1) fiber optical cable module (no longer required).
7. Insert red (rt) insert from new (M2) fiber optical cable module into old connector housing on next ring component and lock connector housing.
8. Reconnect connector housing to next ring component.
9. Route (M1) fiber optical cable module (new) from radio (A2) or  COMAND operating, display and control unit (A40/3) to shift gate through opening on noise insulation (arrow) and below ventilation duct.
10. Route (M1) fiber optical cable module (new) at right on shift gate along present lines and continue on center duct to rear and fasten.
