I have searched the forum with no definitive answer but why would it be that Siri does not function correctly in my early 2015 GTD with Discover Pro? It intermittently works (I am aware the cable needs to be plugged in) but also if responding quickly to a message it will not allow dictation when either microphone button is pressed on the iphone. Is this is known issue that cannot be worked around? Does an upgrade to MIB2 or 2.5 sort this out? Thanks in advance.
