2. Connect black 1-pin coupling (12.1) of TMC navigation module antenna line (12a) to FM/TMC antenna splitter (A2/98).
3. Route TMC navigation module antenna line (12), as shown, along existing wiring harnesses and fasten in place using cable ties.
4. Install GPS antenna adapter line (5) into free contact cavity of white 2-pin coupling (12.3).

   The GPS antenna adapter line (5) was routed into the front passenger footwell when installing the GPS antenna.

5. Remove on-board antenna line (FM2) (13b) from contact cavity "1" of white 2-pin coupling (13.1).

   The on-board antenna line (FM2) (13b) is connected later on with an adapter line to the FM/TMC antenna splitter.

6. Install the angled connector of the 1600 mm long antenna line (FM2) (9) into contact cavity "1" of the white 2-pin coupling (13.1).
7. Route the 1600 mm long antenna line (FM2) (9), as shown, along the vehicle wiring harness to the previously installed FM/TMC antenna splitter.
8. Connect black 1-pin coupling (10.2) of 4700 mm long antenna line (FM2) (10) to black 1-pin plug (9.2) of 1600 mm long antenna line (FM2) (9).
9. Connect white 1-pin coupling (10.3) of 4700 mm long antenna line (FM2) (10) to FM/TMC antenna splitter (A2/98).
10. Loop the 4700 mm long antenna line (FM2) (10) and 1600 mm long antenna line (FM2) (9) that are connected to each other, as shown, behind the floor covering, and then fasten in place using felt tape (14).

11. Fasten the 4700 mm long antenna line (FM2) (10) using cable ties to the vehicle wiring harness.
12. Fasten the 1600 mm long antenna line (FM2) (9) using cable ties to the vehicle wiring harness.
13. Fit the white carrying element previously removed from the 1600 mm long antenna line (FM2) (9) to the on-board antenna line (FM2) (13b).

    The antenna line (FM2) (13b) was installed in the white 2-pin coupling (13.1).

14. Connect white 1-pin plug (11.1) of 1700 mm long antenna line (FM2) (11) to white 1-pin coupling (9.1) of antenna line (FM2) (13b)
