Apple Carplay Audio Source Issue

I have an iPhone 7 running iOS 10.3.3, and my car stereo is a Pioneer AVH4100-NEX. Apple Carplay used to work fine until iOS 10.3.2, but since then sound for phone calls will not come through the radio. The incoming call displays on the radio screen and when I hit "Answer" the phone automatically goes into private mode, which means I have to pick the phone up and put it on Speaker to hear the call. I also noticed that when I pick the phone up there is no option for "Audio Source" as there used to be.

I have limited this to an Apple Carplay issue because as soon as I unplug my phone from the Radio and discontinue Apple Carplay, calls will display, and answer through the radio, and my iPhone contains the "Audio Source" button again, where I can choose the audio source to AVH4100-NEX, Speaker Phone, or Private.

Any ideas why this may be happening?

Thanks,

- Dan

iPhone 7, iOS 10.3.3

I think this was answered, I had such a hard time finding this out. The HU has a front and rear channel. The audio for phone and siri in bluetooth or carplay is the front channel. IF the rear is used then you have no audio for the phone. You can test this by playing any source and then moving your fader all the way to the front. if the sound stops then there is your answer.You have to change the hookup and use the front channel. This will go to the amp in the car and then all the speakers will work and you will have phone and siri audio.

After numerous trips to installer and updating firmware and BT software, I called pioneer and they knew about this issue immediately. Hope this helps

I just took my Kenwood DDX 9704S back to Stereo King today for the same problem. In my case the CarPlay update had changed from using all speakers to front speakers but they had routed the rear preouts for phone audio not the front. A quick wiring change and presto, I can hear incoming phone call audio.

I just bought a new after market stereo for my car. Everything works with apple carplay except the phone app. I am having the exact same issue as Dan. I only have the option to turn on my phone speaker when making or receiving calls. Audio works fine from every other app. I have an iphone 7 with IOS 11.0.3.

Did anyone find a fix for this?

I have a similar issue. iPhone 6s running 11.1. VW Golf & CarPlay. After one successful phone call the sound of an incoming call vanishes. Next time I connect all is well and then the same thing happens.

Hi Becky,

Thank you for your resonse. I have tried all of these suggestions but the problem still persists. Here is a screenshot of my phone while connected to apple carplay, both the phone and the apple carplay screen. Notice how it just has the speaker option as opposed to audio source.

Thank you

I am having the same problem. I've tried the above steps and I can get my phone to link to my car but no audio comes out. As a result, I can no longer take calls through my car speaker when I'm driving and I can't play music from my phone to the car speakers anymore. Please help!
