"Apple CarPlay not using cars built in microphone for phone calls: I’ve tried this and it doesn’t work. From what I have read over the last two months is there are a lot of vehicles that have the same problem and it looks like it’s an Apple setting and not a vehicle setting. so I’m hopeful that Apple will help us out with this."
