Problems with voice during CarPlay calls since iOS 11.3

iOS 11.4 pubblic relase installed and the problem is solved. From the changelog: “Fixes an issue where CarPlay audio could become distorted”.

Dear all,

I'm experiencing the same problems when calling using CarPlay on 11.3.

I have done the following actions trying to resolve the this:

1. Turned Siri on

2. Restarted phone

3. Official Apple USB Cable

4 And have the latest version of 11.3

This unfortunately resulted in no change and still have the issues. After these actions, I have restored my phone back to IOS 11.2.6 and the problems when gone.

Please Apple solve this issue because this is really annoying for people when I call, and I have to switch to bluetooth to have a normal call.

Happy to report back that after a week on the public beta 11.4 (15F5061d) (this is the version prior to the most recent one), everything has returned to normal on my iPhone SE. Short of installing the beta, your only other possible solution is to make calls via FaceTime or Skype or other service when connected to CarPlay... Siri will set it up for you and for whatever reason, these were clear for me even when using the cord. I am still not 100% convinced this problem is defeated, because my first test after installing the beta I thought was a fail. However, later in the week I realized that I was using CarPlay and no one was complaining. This made me think that maybe it as an app or combination of apps being open that caused the problem--and it was only a matter of time before it returned... Except for one unexpected piece of good news... One person said that I had had a subtle echo for TWO YEARS that he just decided not to bother me about...and now this is gone as well. Will come back to report more if: a) it all falls apart, and b) after I upgrade to the latest public beta.

Just remember--this has NOTHING to do with your car or head unit, and always make sure you read the later comments before following instructions of the inevitable first post that says "Thanks for reaching out to the Apple Support Communities! It sounds like....(your specific problem), I recommend taking a look at this article...." The intention is good, but the laundry list of things to try is posted despite the poster having never heard of your problem before and having no knowledge of whether the list of solutions will work in this specific case. In other words, the helpful person SHOULD say "I have never heard of this problem, but here is a general list of things to troubleshoot." By not saying that, the implication is that following the (often time-consuming) listed steps has solved the problem for some people and might solve it for you. It is often a good idea to try the basics first, but it is even better to read ahead and decide if trying the basic troubleshooting path still makes sense.

My iPhone X was already updated to 11.3.

Kenwood was using 1.3 (2016/17?). I updated it to 1.4, Oct 2017 release, which is still quite outdated.

Quality went from completely illegible to tolerable, similar to BT quality.

Looking forward to 11.4...might try it next week.

Hi all,

I'd like to point the "newcomers" to ios 11.4. After installing the beta release the problems are gone and according to some news portals the official release should be soon (what ever this means).

So please be patient (or switch to the beta version 😉)

Cheers,

11.4 solves it. But it sure would be nice if Apple would put out a statement while the problem is happening and let us know it is a known issue and going to be fixed.. but instead, we all have to come into the forums, try to establish that we are not alone, Buy new cables unnecessarily, reset and restart our devices… And waste our time trying to fix something we have no way to fix. I’m glad they fixed it in 11.4,

Hi All,

I had a the same issue with crackling noise on the receiving end using my Iphone 7 in a VW Arteon 2018.

I sounds like an software problem with the noise cancelling failing. I soon as you speak yourself, the noise is gone.

I did the following:

I tried an Iphone 5s : works

I tried an Iphone 6: works

I tried an Iphone 7: works:

I tried an Iphone 7 plus: works

All different service providers and sim cards

Convinced it was my phone (my specific phone) I went I trying a new Iphone 7 plus. On entering my sim card. same issue again.

Then I tried my simcard in my wifes Iphone 6: and suprisingly It was bad too.

How on earth can the simcard be an issue here? I cleaned my simcard using contact spray, placed it back in my 7. Gone was the problem. It took me a week to get here.

I am still somewhat surprised. What also can be the case. I have read on other forums that specific providers might have issues. So the answer in my case might be eighter the simcard itself making a bad connection. Or more likely: by chaning the simcard you force your phone updating the service provider settings, whilst setting things right.

I am still in a bit in disbelieve that this is what sorts out the problem. I will be testing more next week. This is what I did. Maybe it helps for some of you too.

Good Luck!

Hi All

I had the same problem - had all the hardware and wires checked. Updating to iOS 11.4 sorts it!

I am having the same problem as everyone else. This started the minute after upgrading to 11.3. I even tried the new upgrade to 11.3.1 with no fix.

I contacted Kenwood support to see if they knew anything and this is their response:

There is a problem we are seeing since the 11.3 update . Waiting for apple to fix and do update .

Use bluetooth till update is posted .

Thanks Rory

Good news – at least in my case!

With iOS 11.4 Beta 3 (15F5061d) on an iPhone 7 my earlier described phone call audio problems within CarPlay and a KENWOOD DMX7017DABS are gone. I did three longer phone calls and every callee could understand me.

*Phew* :-)

I have KENWOOD DNX694S. Looks like a lot of people are having issues with KENWOOD. Interesting. I downloaded the 11.4 beta. I’m using a iPhone 7. My problem was when I called a land line. I could here the other person but they couldn’t here me or it was very garbled. Cell phones didn’t seem to be a problem. Once installing the beta the problem went away. Here’s hoping the problem is fixed.

Here’s the link. Obviously it’s at your own risk..... it’s a beta. https://idmsa.apple.com/IDMSWebAuth/login.html?appIdKey=4b98a8e6a3a3ce265b93c902 07c442b53c45a1afa9ff1dc9bde8bb6928078d3b&path=%2F%2Fbetaprogram%2Flogin_to_legal &rv=2&view=3

I can also confirm that the problem is fixed with iOS 11.4. Kenwood ddx9704s.

after the iOS 11.4 update the CarPlay works.

update to iOS 11.4 and you'll see that the problem you had after the 11.3 update resolves.

Greetings, XWB!
Thanks for reaching out to the Apple Support Communities! It sounds like you are having an issue with your voice to be distorted with the connection from your iPhone to your vehicle through CarPlay and I’m happy to help! I recommend taking a look at this article with steps to Set up CarPlay with your iPhone. Specifically:

If CarPlay doesn't work like you expect, here’s what you can check. After each step, try using CarPlay again.

1. Make sure that Siri is turned on.
2. Restart your iPhone and your car. Depending on your car, you might see the CarPlay Home screen when you turn it on. If you don't, look for the CarPlay logo on your car’s display.
3. If possible, connect your iPhone to a different USB port in your car.
4. Try a different Lightning to USB cable. Make sure that the cable is certified.
5. Update to the latest version of iOS.
6. Check your car’s manual for help. You might need to install firmware updates for your stereo.
