As part of fitting my ambient/map lights I found that there's an OEM mic fitted in the unit. As far as I know there's no Bluetooth fitted to the car (no "phone" plug on the back of the OEM head unit). It seems a bit odd - but maybe they are all like it? Anyone know how I can access the "other end" of the mic connection? - I could do with plugging it into my Parrot kit and pulling out the cheapo looking clip mic.
