I purchased this
adaptor for less than £10 from ebay. It ticks all the boxes for me and is the most discrete adaptor I could find. The 3in1 adaptors like this
one dont come with a mic so wont work as a hands free without additional adaptors.
My intention is to have the plug fixed to a Brodit mount. The cable is no thicker than headphone cable. This 90cm cable will route to behind the steering wheel on the cowling. The adaptor is flat and low profile with the answer/hang up button on the top. Easily pressed through the steering wheel spokes. The audio 3.5mm and mini USB leads plug in at right angles to each other but will easily route out of site, behind the dash to USB car charger and 3.5mm MP3 In socket on the head unit.
It all works as expected, and even at Motorway speeds callers can hear me clearly. Voice Command works fine, TomTom and Media Player sound great. My only problem is alternator whine when charging, which I think is just an earthing problem. When I get it all properly finished I will post some photos.
After work, wife, kids etc. have finished with me.
