I have an iPhone 6 with iOS 11 and a 2017 Honda Civic. Recently the Bluetooth in my car will not allow me to make or answer calls over Bluetooth. The phone is paired to the car, I can play music and listen to voicemails over Bluetooth, but not make and receive phone calls. When using the phone and it will not even give me the option to switch to handsfree. How do I fix this problem?
