I Use my cars bluetooth funtion to listen to music, change the tunes from my steering wheel, and to answer calls. My problem is that sometimes, if I'm listening to music, it will play on the backgroud if I answer the call and it's super annoying bacause I cant hear the person I'm trying to have the convo with. I've tried restoring my phone, I've actually changed phones since I got the car and I've always had this problem. I can't reproduce the problem but I'm guessing it's an iOS issue. Help, it's annoying! :/
