The Allow "hey siri" seems to have affected my cars bluetooth. When I get into the car and device is connected to charger, I see my car in listening mode via the phone. Before, my normal radio played etc through the car. To invoke siri, I used to press home button and speak into it or when it was getting charged, it use to just listen. But for some reason, I cannot get the car to to not show the listening to phone mode off. I have to go and turn Allow siri off. I did that and car was fine. Strange.
