I have just replaced my mobile with a Samsung J3 17. Through Bluetooth have paired it to the car and all works well. That is to say it makes and receives calls etc. When I speak the other hears me when they speak they do NOT come through the car speakers until I select from the cars system Freespeach. When the call is over Freespeach is disconnected until the next call when I have to select it again. Non of this happened with my old phone so in pairing the new I seem to have somehow changed the car settings. Its not the phone settings cos it works well in my brothers car and his phone also does not work in mine. Can anyone help please.
