Hey, I have a 2018 Sierra SLE 4x4 half ton. It’s fully loaded other then leather. Recently I switched from Samsung to the new I14 mini IPhone. I synced it ran the new contacts and everything was good. Then one day I hooked the phone to the centre council and it asked to update the new IPhone sync. I excepted the update and since my mic stopped working. I can push the call button and it asks me the usual. But when I tell it who to call nothing happens. So I tried calling direct from phone and I hear it ring, and the other people but they don’t hear me. What’s going on and how do I fix it?????
