I wired up my Nokia full duplex hands free kit yesterday! here is a pic, it's mounted on a OEM MB telephone console with integrated speaker (thanks MBenzNL) - I discarded the nokia speaker and wired it up to the console speaker, the mic is mounted in the headliner and power is taken from my passenger (usa driver) side a piller distro block. It charges the phone oncee on ita nd I have set the light to stay on in the phone when it is at its cradle for maximum BLING. It also mutes my Sound system and the screen on the cd player starts to animate 'Telephone' and some other funky shiz while the radio is muted - AWESOME!!! get one now!!
