Hi. I bought a 2014 Kia Sorento LX, 4 cylinder (in Canada). I can not get the basic voice commands working like "Help", "FM 1", etc. I believe the microphone is disabled. It does not understand what I say. Also, When placing phone call, I can hear the party very good. But the other end, they don't hear me at all. Again this is why I believe that the microphone is not enabled Please help. How do I enable the microphone? Thank you.
