I have a 2012 buick verano with intellilink. Up until yesterday my bluetooth worked fine. But now for some reason it wont work. I have unpaired and repaired my phone. The phone calls still work and come through over the radio but no audio from my phone. When i try to check the bluetooth settings in the radio it will not let me. The blue bluetooth icon at the bottom when you hit source is usually lit blue but it is grey and i cannot even go to it. I can connect my phone via bluetooth but no bluetooth audio. If anyone knows what this may be or can help please let me know. Thank you.
