964 Blue Tooth Mic install

[r4_rick]

I've just taken a nice alpine head unit out of my van and want to put it in the 964, would like to get the full use of the Blue Tooth too, any ideas on how to run the wire from the head unit upto the top of the a pillar, the trim doesn't look to come off too easily! back in the day I would have thought many an alarm installer has tackled this challenge for the movement sensors?

Just mount it at the base of the A pillar, access through the aerial hole
