I have a third-party Britelink Bluetooth adapter for my car. I plug in a 3.5mm audio cable into the audio-in port in my car and it becomes bluetooth. Now, when I use Siri, I THINK it thinks there is a microphone connected to my bluetooth or it's trying to use my bluetooth (which the third party adapter doesn't have a microphone). Is there any way for Siri to use the Speakerphone functionality in this instance? Am I making since?
