Car bluetooth not working correctly after IOS update 15.2
My 2017 Buick Enclave bluetooth worked perfectly in my car until the recent update. The bluetooth connects BUT nothing comes out of the speakers. I will get a call normal I would push "accept" on the screen of my car and it routes the call through my car speakers. Now when I hit accept on my screen it brings it to my iPhone 11. Also, same thing with music. It shows selected music on screen of car, I can pause, play etc but nothing comes through speakers anymore.
So far I have done the following:
-unpaired and repaired
-turned on and off my phone
-turned my bluetooth completely off and then on. (it has no problem connecting to bluetooth only a problem coming through speakers.)
This is beyond annoying! I work out of my car and need these features to work. Please help!
