Bluetooth phone calls

[AC Question]

When making or recieving phone calls in my truck, I can hear everything fine like the ringing of the phone and I can also hear the person on the other end. They however cant hear me at all. If I turn Bluetooth off I can call them and everything works fine. Why cant people hear me when I answer the phone via my trucks Bluetooth?

Welcome to Android Central! Which truck do you have? Do you know where its mic is located? If so, make sure it isn't blocked. Can you tell if the truck's mic works with other devices?
