iOS 11.3 Carplay Call Quality Issues

Ditto. iPhone 6s on iOS 11.3 connected to a kenwood ddx9704s. Car play works great (nav, texts, music, etc) except for calls. Bluetooth calls are perfect. Using Apple lightning cable hooked to Ken woods provided usb extension.

I have the same issue with my iPhone se on IOS 11.3, really irritating. I just had a new Kenwood with CarPlay installed in my truck to specifically to use carplay with and now it is all total cr$p. I am getting really tired of investing in the apple line with it poor QAQC. My industry would not tolerate this. 😟 Might as well use an android with Bluetooth.

I have the same problem. Iphone 7 on 11.3.1. Kenwood DMX7704s. Audio and microphone work great over bluetooth for calls. When using wired CarPlay - music plays fine, Siri understands me perfectly, but on audio calls through CarPlay, I can hear the other party perfectly, but they here nothing but a garbled mess. Apple, please help ASAP.

Yes this is an issue with the 11.3 update. I swapped my phone with my daughters since she never updates and all works fine on 11.2. Kenwood has a ticket into Apple to fix it. I have DDX904S. I will not update until this is resolved. I image at some point Apple will force the upgrade then I will switch to Android.

11.3 update included this:

Telephony

Available for: iPhone 5s and later, and WiFi + Cellular models of iPad Air and later

Impact: A remote attacker may be able to execute arbitrary code

Description: Multiple buffer overflows were addressed with improved input validation.

CVE-2018-4148: Nico Golde of Comsecuris UG

I am curious what that is. Because what I hear sounds like a buffer issue.

Hi

I have a jvc kw v930 bwm the latest available head unit in South Africa from Kenwood sister company jvc..

Ever since iOS 11.3 on my iPhone 7 Plus people answering CarPlay calls via the lightning cable aren’t able to hear me.. audio is garbled on their side, I am able to hear them clearly and Bluetooth calls seem fine both ways ...

I took my phone to the car audio fitment place and tried and another iphone with iOS 11.3 and was able to replicate the issue..

Strangely However when we tried my phone on a Sony CarPlay Head unit the garbled audio issue didn’t affect the Sony unit...

This leads me to believe that it’s an issue with iOS 11.3 and JVC-Kenwood...

Note that iOS 11.3.1 does nothing to fix the issue..

I have reset my phone to factory defaults, tried various lighting cables, reset the jvc Head unit to factory defaults and still no joy..

there is another issue with jvc and Kenwood when it comes to usb flash music playback on dual usb equipped head units.. if you play music off the flash disk and an incoming call is received via lightning/CarPlay the head unit freezes up completely..

Apple JVC Kenwood I have videos to prove this

I have exactly the same problem.

When making a CarPlay phone call I can hear the person that is talking perfectly but What they hear is a garble and choppy, They tell me I'm breaking up. If I disconnect the lightning cable and make the call using Bluetooth they can hear me just fine.

Brand new Kenwood DDX6704S, New iPhone X running the latest IOS 11.3.1, using the brand new out of the box lightning cable. Rebooted the iPhone and Stereo ( actually did a cold boot of both devices) I even went as far as plugging the Lighting cable directly into the back of the car stereo. This made absolutely no difference.

My issue with 11.3.1 is now that I'm updated to the latest IOS I now have issues with CarPlay. I have an iphone x connected to a Pioneer AVH-2300NEX. My issue is all of carplay works except phone calls. The calls show up on screen of the radio but the only way to use the phone is through speaker phone directly on the phone. Yeah it's still hands free but I can barely hear my callers and they can barely hear me.

Same problem. iphone 6. 2018 aftermarket headunit from Kenwood with Apple CarPlay. Problem started with ios 11.3.0. Android Auto in same vehicle with same headunit does not have the problem. Bluetooth calls via iphone outside of Apple CarPlay does not have the problem. Problem IS APPLE.

I have the exact same problem. Brand new 2018 Jeep Wrangler Willy’s, bought yesterday...Cartoys installed a brand new Kenwood hu today. Then....every single person I tried to call and talk to today said “I can’t understand you”...every single time I had to unplug my phone and use Bluetooth...$1340 bucks for the Kenwood Hu and a couple cameras, installed....and the only real reason I bought it was for CarPlay...$1340 bucks—-oh, I said that already...I‘m a pro photographer, I have 2 Ipad pros, 9.7 and the latest model 12. I have 3 iPhones, 2X’s (one is my gf’s, and I have an 8(red) I use as a hotspot...I have a MacBook Pro as well...two years ago I swore by Apple...100%...after all the problems I’ve had lately, with the phones, the iPads, the constant useless updates and the $1000 iphoneX just having issues EVERY SINGLE time I turn around...I’m ready to have a big Apple sale, and get myself a pc and a S9. I miss you Steve.

Hi

See this thread above...

People are claiming that the beta version 6 of iOS 11.4 fixes this issue not sure when the official release will be available for download.. so try at your own risk...

That said the JVC-KENWOOD units are crap I’m swopping mine Jvc kw v 930 Bwm for the alpine ilx 702d in South Africa this weekend...

Prior to iOS 11.3 the JVc unit crashes whenever you play music of a flash disk and have CarPlay connected on dual usb JVC-KENWOOD head unit..

As for JVC-KENWOOD support that ***** big time...

I’ve been having issues since I purchased this JVC-KENWOOD product since December 2017....

Dual usb head units that support CarPlay just don’t seem to work..

It’s no wonder alpine and a few others only released single USB ports

Just installed JVC KW-V830BT and with my iPhone SE IOS 11.3.1 voice through USB is garbled however voice through bluetooth is fine. Tried 2 different Apple cables and made no difference. I tried my iPhone Se with IOS 10 and voice is good on both. If it's not the IOS it's the phone itself. Definitely not the receiver or the cable.

When a audio company finally gets into the 21 century and starts paying attention to problems and informing their consumers asap i'll be buying exclusively from that company. If I owned Kenwood and found out this was a known issue on an open board and my employees had not so much as mentioned it i would be telling them to start learning to say "would you like fries with that". Yes a representative of Kenwood should have been on the board paying attention daily and chiming in. There is no telling how many hours folks have wasted taking there cars back to an installers and having them check connections or just trying to fix it their selves. It took me 2 days of searching just to find this board. Issues like this should be easily found in a simple search. Thanks to the to the people on here i did not waste anymore time. Thank you for doing what Kenwood/JVC and Pioneer should have done their selves.

Having the exact same problem with phonecalls over carplay after ios 11.3. speech quality is unusable!!
