I want to remove the plastic cover on my drivers side windscreen pillar to run a cable up to the sun visor for my hands free kit for my mobile phone. Has anyone done this yet. My new stereo comes with integrated bluetooth,both stereo for playing music from the phone and for making calls. the microphone is a hard wired unit and I want to fit it near the sun visor without wires showing. This will all be fitted when I upgrade my Speakers , change the bulbs on the centre console, and fit the scanga
