No voice for phone or navigation
I have just purchased a 2013 Megane with a Carminat system. I have connect my phone to Bluetooth however when making or receiving calls I cannot hear any voices. Also have no GPS voices despite trying several tests from the menu. Bluetooth works fine with everything being visible as you would expect. Bluetooth music streaming works fine and I can hear phone alerts. Adjusting the phone volume works fine. I have been through every setting possible and tried a second phone. I am using iPhone 7s and 8s. It is very weird and very frustrating. I have also reset the system and removed the sd card. Help!
