I thought that this on the dash was perhaps a mike and mute button for a phone but never checked into it. Now ,looking into it,there is no phone input or Bluetooth. It is perhaps the mike for the overly complex,unexplained security system. A loud noise (or dog bark !! ) will see off the alarm. Now what does the button do??
