Installing the microphone requires removal of the A-Pillar Trims, the sun visor and part of the overhead console. The final parts of the install such as the connecting to a bluetooth car kit or the RNS 510 are covered separately.
Step 2 – Pop off the screw cap using a fine screwdriver on the sun visor mount closest to the pillar and undo the torx screw, than tilt the bracket forward which will allow the sunvisor to hang from it’s harness for the illuminated mirror (if fitted – otherwise you can remove it completely).
Step 3 – Remove the light fitting using a trim removal tool and and gently levering on the side closest to the door. Now you insert the end of the microphone cable at the top of the A pillar and jiggle the wire around until you can pull it through the hole left by removing the light fitting (you may want to use a draw wire, 2.5mm home electrical cable is ideal).
Step 4 – Using a trim removal tool and working from the side that is towards the rear of the car pop the cover off that covers the area where the microphone installs (microphone installs in the rectangular area shown towards the top of the photo on the right hand side).
Step 5 -Undo the two torx screws visible in Step 4 above and gently pull the panel down working from the side closest to the rear of the car as there are a few clips at the front holding it in place. Disconnect the wires to make installing the microphone easier.
Step 6 – Using a draw wire bring the microphone cable over to the console area.
Step 7 – Remove the foam piece and install the microphone, it only goes in one way and is a tight fit.
Step 8 – To prevent rattles in the ceiling wrap the cable that runs from the A pillar with foam or rubber tape, make sure you wrap it along the length and cable tie it at each so if the adhesive fails due to the heat it won’t unwrap itself.
Step 9 – Connect the cable to the microphone and wrap the connectors with foam tape to prevent rattles. Reconnect the harness that connects to the console at this stage. And put the overhead console and mirror light back together.
Stage 10 – Cable tie the microphone down the A-Pillar as shown to prevent rattles and to keep it out of the way of the airbag.
Stage 11 – Re-install the A-Pillar following these instructions – Volkswagen Golf A-Pillar Trims – Removal and Installation
