Iphone 15 with Aux Cable
I have an older car and have used an aux cable to connect my iPhone 11 to my car stereo for years. It works great for music, audiobooks, phone calls, everything. I recently upgraded to an iPhone 15. Now the USB C to Aux cable works for music, audiobooks, anything i want to listen to. It even works for Siri and voice to text. But with phone calls, I can hear the caller but they can't hear me. It seems to shut off the microphone.
Any help would be appreciated.
