It must be a microphone as it is only connected through a small wire. I unclipped it and below is a closer image. There is sticky tape on the back but it was just laying on the floor. Is this the microphone to the entune hands free dialing or voice activation? If so, why is it under my seat and not in a better location? I can't tell what it was connected to without removing the carpet. Is there a way to do that?
Found what it was connected to after pulling out all my trim and weather stripping. This must be that sensor the reverse sensor that beeps whenever my rear bumper gets close to something. I always thought that came from the camera. So I am guessing what I pulled out is a speaker and not a microphone. Is this not stock?
