Anyone managed to get Siri to activate via the multi function steering wheel? Or any other solution? I dont have a MFSW but what I am thinking of doing is buying one then cannibalising an iphone 5 set of headphones wiring the microswitches in the iphone headset directly up to the microswitches on a MFSW cannot see any reason why this would not work and then would have complete handsfree control over the iphone including skip forward, back, volume and siri activation using the 3 microswitches with the audio being passed to the aux in unless there is a more elegant solution like bluetooth?
