The design and the placement of the microphone hasn't changed for most owners since 2012 when it was introduced so much of the information applies to the 2016 as well as the upcoming 2017. The only drastic things that have changed are the headunit and the Eyesight (as the assembly holding the microphone has changed) feature.
The noise seems to be coming wind noise off the roof and the low amounts of insulation (ie none) between the roof and the microphone assembly.
BTW. Welcome to the forum!
