Bluetooth error with Kia Car and iPhone 5s
I have connected iPhone 5s with Kia car which connected okay, however when receiving calls it connects the call but then not plays the audio via car. When you make a call it works correctly. (PS connected a iPhone X and works great)
Also it will not reconnect to car without going into Bluetooth settings on phone.
Can anyone tell me what wrong or is this what should happen?
On iOS 11.4.1
