Part 2

NOTE:
Figure 18 shows the DIP switch settings for the frequency range 87.7 - 107.9 MHz as an example.

The DIP switches are arranged from the left (DIP switch 4) to right (DIP switch 1), starting from the connection side of the control unit (Figure 18 -A-).

6.3 Stick loosened protective film on the control unit.





6.4 Route wire harness --> Figure 19 -A- to the installation slot.

NOTE:
Do not confuse antenna connectors because if you do, there is no guarantee that the music player interface will function correctly.





6.5 Connect standard antenna connector from diversity control unit (angled) --> Figure 20 -D- and antenna connector (straight) from the antenna line (retrofit kit) --> Figure 20 -C- to the control unit --> Figure 20 -A-.

Plug in wire harness connector --> Figure 20 -B- and tighten locking screws.





6.6 Pull protective film off the double-sided adhesive tape on the control unit --> Figure 21 -A-.





6.7 Insert control unit --> Figure 22 -A- at the left in the PCM installation slot and press on it so that the angled antenna connector --> Figure 22 -C- is positioned between the bars of the installation slot --> Figure 22 -B-.





6.8 Wind up the rest of the wire harness (retrofit kit) and route it in the side area of the center console --> Figure 23.

7 Connect wire harness (retrofit kit).

WARNING:
Working on the vehicle electrical system

- Risk of short circuit and fire.

--> Disconnect and cover the battery.

--> Route electric wires without tension so that no chafing occurs.

--> Secure electric wires to existing wires/components using tie-wraps and/or wrapping tape.

7.1 Disconnect the battery. --> Workshop Manual '2X00IN02 Work instructions after disconnecting the battery'





7.2 Release secondary lock --> Figure 24 -A- on 8-pin connector.

7.3 Join RD 0.5(2) line (retrofit kit) to RD/GN 2.5(2) line (term. 30, chamber 4).





7.3.1 Press socket contact of RD/GN 2.5(2) line out of the 8-pin connector (chamber 4) using press - out tool 88044 --> Figure 25 -A- (--> Figure 25 -arrow-).

7.3.2 Cut socket contact. Strip the lines.

7.3.3 Join RD 0.5(2) line (retrofit kit) and RD/GN 2.5(2) line and crimp together with a new socket contact.

NOTE:
Ensure socket contact is seated securely.

7.3.4 Insert socket contact into chamber 4 of the 8-pin connector.

7.4 Connect BN 0.5(2) line (retrofit kit) to BN 2.5(2) line (term, 31; chamber 8) and WH 0.5(2) line (retrofit kit) to WH 0.5(2) line (antenna output terminal, chamber 5) as described in Step 7.2.
7.5 Lock secondary lock on 8-pin connector.





7.6 Open line bracket --> Figure 26 -C-.

Place the antenna line --> Figure 26 -A- and the wire harness (retrofit kit) --> Figure 26 -B- in the line bracket.

Close the line bracket.

8 Concluding work

8.1 Install the remaining parts of the center console. --> Workshop Manual '681719 Removing and installing center console'

8.2 Install PCM. --> Workshop Manual '911019 Removing and installing PCM display and operator control unit'

8.3 Connect the battery. --> Workshop Manual '2X00IN02 Work instructions after disconnecting the battery'





8.4 Switch on PCM.

NOTE:
When using the "Autostore" functions (AS memory level), the station with the RDS code "AUX" cannot be displayed correctly in memory fields 0-9.

Actuate the search button until the station with RDS code "AUX" for the music player interface is displayed.

Store the station with the RDS code "AUX" to any memory location in memory level A or B as required.

8.5 Read out the fault memory of all systems, correct any existing faults, and erase the fault memory.

8.6 Disconnect battery charger. --> Workshop Manual '2X00IN03 Battery trickle charging'
