Iphone 13 pro max will not sound while driving

I have a BMW X3 and my phone will not give any sounds or notifications while my phone is hooked up to bluetooth. I have checked that focus and drive mode if off. Also if I am the passenger in my car and watching a video, there is no sound. I don't want to turn my bluetooth off because I live in a state that is hands-free. Is there a way to have your texts or other notifications come though your phone and still be hooked up to bluetooth. This is very inconvenient and never happend before getting the Iphone 13.
