This afternoon's taskbegan with putting the microphone in place, so it was off with the ceiling light cluster.
The removal tool pictured here and the set that came with it absolutely crucial. I've used screwdrivers and the like in previous cars to remove interior trim and I've always regretted it.
With the dome cluster out, there are two torx T15 screws to remove. Once they're out you pull the remaining housing downwards so it unclips, then forward. With that bit out there was what seemed to be an original mic cable and plug, but held in with tape and with rotten foam:
That area left of the foam with three prongs is where the mic goes. You have to remove the blanking plug first, then the mic has only one way to fit.
The mic is now fitted in the picture below:
What might not be clear from the picture is that the mic wiring I was sent has the mic cable divided into a shorter bit that connects to the microphone and a long cable that goes from the housing pictured above all the way to the radio. I undid that connector then set about the mext part of the task which was threading the long cable through the passenger side A-pillar. I got this idea from this thread:
viewtopic.php?t=48421&start=30. There seems to be less gubbins in the passenger area, and the fascia there is relatively easy to remove.
First, I removed the trim next to the hinges:
Then, I prised away the A-pillar trim, getting it mucky in the process. Grrr!
I started at the base of the pillar, threading the wire as if it came from the dash. There were some loops along the inside of the A-pillar that seem purpose-built for threading wiring through, so I duly did so. Then with the wire out the top of the pillar, I pulled it across, threaded it through the ceiling housing with the mic and plugged it in. I then shoved the exposed cable stright into the headliner with a removal tool.
Afterwards I put everything back into place, except the sodding map-reading lights. I don't know what I'm doing wrong but there are some metal clips that I can't get to work! $%$&ing annoying! Mic looks good though.
Next up, I removed the dash fascia. Dead easy on this car. Pry out the trim and undo three torx screws:
It's hard to see because the cable is black and everything is dark, but the picture below shows where I threaded the loom from the passenger door side
Then I just threaded it all to the cavity above the radio and shoved the remaining loom in there, waiting to just hook it up when the radio arrives. Again, hard to see here but that cable right in the middle is what leads to the mic.
That's the story so far. To be honest, it was rather easy especially for a ham-fisted dunderhead like me. I usually f**k up terribly or ruin and break bits of trim (nearly boll*cksed up a vent today, but I got away with it), but this C5 has proven to be rather idiot-friendly, and as a bit of an idiot myself, I'm rather happy that it's the case.
Now I'm just waiting for the actual head unit. Hopefully it'll get here this week.
Until then, if there's anything that didn't seem clear in my description, let me know and I'll try to clear it up.
