Problems with voice during CarPlay calls since iOS 11.3

Same problem over here with iPhone 7 (iOS 11.3) and Škoda Octavia 3 (2016). The communication partner can‘t understand me but I can understand her / him quite well.

If I make the call I disconnect from Carplay and use the Bluetooth connection at the moment. I don’t know if this process is quick enough for incoming calls yet. Very annoying!

I hope Apple is

working on a solution for this issue by now.

Same for me, yesterday I went through diagnostics on the phone with a Senior Advisor followed by full log upload on a special link they provided. They're going to give me a feedback in about 4 working days but I guess we'll have to wait for the next iOS update.

It's a problem they're investigating specifically about VW Group cars, but hopefully it will lead to a solution for all multimedia systems.

Support was very kind and efficient both on Twitter and then on the phone, thumbs up!

I can confirm that my call quality is only affected with a Carplay connection and not over bluetooth or a wall connection in any way.

I have changed SIMs, tried LTE, 3g and 2g and wifi. Carplay calls cut in and out in every scenario. Again I am running OS 8.4 on an iPhone 5s so the bug goes back that far. I have also tried a 5se on 10.1.1 and a 6s on 11.3 on the same Kenwood headunit with no problems.

Tested another phone on my Kenwood 573s headunit. iPhone SE on 11.3.1 no problems at all. This bug can not be only an iOS version problem, it may be in combination with certain head units and possibly carrier firmware.

This has happened to me too in my 2016 VW Jetta. I can hear all inbound calls fine, music, texts etc. Also there is no issue with my voice and my talk to text, but when I receive or make a call...the person on the other end says it sounds like I don't have good reception or my voice is garbled. If I disconnect from Apple carplay and use the VW Bluetooth phone...everyone can hear me fine. I have cleaned out my phone, USB ports, bought new cables, etc. and still experience the same issue with my iPhone 7plus. It super ***** because I do not get all the options via my car Bluetooth that I do with the carplay. Just noticed a new software update...hopefully this will address the issue.

Still the same issue as well.

11.4.1

iPhone SE

Skoda Rapid Spaceback 2015

Seems to me like mainly VW group feedback ? (skoda - seat- vw - audi - bugatti- Porsche)

In any case, it's Obvious that some software issue is at play here, since they attempted to fix it in 11.4

Hi XWB,

I have the same problem since the update to iOS 11.3. I will now make a downgrade again and tell you if it works.

Hello. Nothing will hapen i am sure about it. They will just give you the same crap. Try resetting your phone, change the cables etc.

We can strike Bluetooth off the list. Bluetooth works fine.

My CarPlay is cabled and doesn’t use Bluetooth.

Hopefully KENWOOD will come up with an update soon to keep up with Apple changing this

Bluetooth was reported to be working fine by several people. It does not seem to be part of the problem. Cabled Facetime and Skype calls also not affected. Only cellular calls.

Hello Vincent,

J'ai signalé le BUG à appel ce jour.

Apparement le problème vient de leur part.

Nous allons recevoir une mise à jour le plus rapidement possible.

Il faut donc patienter!

Two threads with the same

iOS 11.4 beta 6 sorted the JVC out... however I’m dumping it for the alpine ilx 702d

We are experiencing the same issue. We have iPhone 6 plus and iPhone 7, both upgraded to iOS 11.3. Calls using Apple CarPlay are garbled for the person on the receiving end but sound fine on our end. We also tried all the recommended fixes from Apple including resetting our phones and using a different cable. Nothing has resolved the issue and as others have already stated, this started after the upgrade to iOS 11.3.

The same problem here with a Kenwood DMX7017BTS car stereo and a iPhone SE. Worked without a problem with 11.2 after upgrade to 11.3, the voice is robotic and the callee cannot understand me. I understand everything. "Talking" to Siri is working fine.

I tried the suggested solutions, even upgraded to ios 11.4 beta, but nothing is working. It is a really bad situation atm.
