Problems with voice during CarPlay calls since iOS 11.3

I have this problem too. My iPhone 7 with iOS 11.3 does not work any longer with CarPlay. When I call the voice is fully distorted. My wife's iPhone SE with 11.2.x does not have any problems, it's fully functional. I am really shocked that such a mess could happen with all the testing.

I’ve got same issue on VW Golf 67 plate

Was working fine until upgrade of iOS

I’ve changed cables and rebooted everything with no joy

Bluetooth works perfect so definitely an issue with CarPlay in iOS 11.3

Please Apple fix this asap

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.

It looks much better since iOS 11.3.1 now. I have a BMW 4 series with wireless CarPlay and it was really slow and not useable since 11.3. Since yesterday it is fluid like before 11.3. Can anybody confirm?

Hello all,

Same issue I noticed about a couple weeks ago. I have a Kenwood DDX9904S, Bluetooth works fine all apps work fine except for phone calls. When talking people complain that they cannot understand me or it sounds like alien talk. I have tried new iPhone lightning cable, resetting and different iPhone same IOS 11.3 and about everything else I can think of. This is a problem. To talk while in carplay you have to disconnect the lightning cable then Bluetooth kicks in and you can talk fine.

UPDATE: I just did a firmware update to my head unit. No good still does not work. Went back to where I had this unit installed they tested with a iPhone 8 same issue. They did say they have had some complaints. I have emailed Kenwood about this and waiting for a reply. Also did the 11.3.1 software upgrade to iPhone 6s and no good. Apple is responsible for all of this. I am ready for an upgrade and thinking about getting an Android. This is not acceptable at all.

I have just got my Seat Ateca back from Seat, they replaced the USB ports and still having the same issue on both mine and my wifes iPhone 7 apple says its the car but Seat says it apple! So annoying!

I have exactly the same problem on my Iphone 6S since i upgraded to IOS11.3 . I can make and receive voice calls via bluetooth perfectly. But when connected to USB my carplay plays my voice distorted. I have tried all the fixes. Its definately the new version IOS problem. I tested other iphones on older version IOS and these work 100%. Come on Apple get your act together.

Have a SEAT LEON FR 2017 and an iPhone6s and have the same problem since 11.3.

Updated to 11.3.1 and still the same issue.

My wife's iPhone still on 11.2.x has no issue on the same car with the same cable.

Please correct this issue asap as it make CarPlay unusable (need to connect via Bluetooth only) and creates a potentially dangerous situation as now needing to touch the phone while driving.

From reading all the replies it is apparently a software issue and you should offer a solution that you have tested with IOS 11.3 or IOS 11.3.1. I have emailed you and no reply.

My phone worked great with 11.26 but you forced an upgrade on us and now a lot of phones aren't working because the software broke them.

I have the same issue and I’m on IOS 11.3.1with an Anker lightning cable and Kenwood head unit.

Maps & Spotify are great via Carplay. Voice calls are great via bluetooth but as soon as I try a voice call via carplay it is distorted and unintelligible.

I have tried all the usual i.e. turn on Siri, turn phone off/on, tried different lightning cables, update IOS etc.

problem persists - come on Apple what are you doing? This is a fundamental feature of carplay!

Same here on VW Golf with Discover Media 2017, on different iPhones (SE, 6S, 7) after updating them to iOS 11.3.

Older Discover Media infotainment in my wife’s VW Touran works fine. Looks like iOS 11.3 broke CarPlay audio call quality on several but not all infotainment systems.

Come on Apple, fix it quickly!

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

Rory,

Same reply Kenwood gave me yet yesterday Apple Techs on Twitter asked if I had done a firmware update on Kenwood radio, apparently they don't read the forums anymore!

Android Auto works flawlessly was my reply 😁 why doesn't iPhone?

Same issue here. Ever since upgrading to 11.3 and now 11.3.1, CarPlay on both my Tiguan and GTI doesn’t work anymore. Calls are distorted. Other people can’t hear me. For sure it’s a Apple issue because I used a friend’s phone on 11.2.6 and the reception is all clear. Calls over Bluetooth works fine. So I don’t even bother with CarPlay anymore and just use Bluetooth. Hope there’s a fix from Apple soon.
