CarPlay voice audio quality when connected via USB is poor vs. Bluetooth on Pioneer AVH-4200NEX

I have the same problem with poor call quality when using CarPlay on my 2017 BMW 430xi. If, on the phone, I switch the audio source from CarPlay to iPhone then immediately back to CarPlay it fixes the staticky noise. Anyone have a solution? Not too impressed with CarPlay so far. Seems super buggy.

Yep, I too have this problem.

I purchased a Kenwood DDX-9017-DABS (particularly for its CarPlay capability) but am disappointed to find that the telephone call quality when plugged-in via USB and CarPlay is significantly poorer than via Bluetooth. In my case it seems that outgoing audio is particularly affected, with incoming less so. I had originally assumed there were problems with the supplied microphone or its placement!

I have now been back to the retailer three times and he has advised that he is now aware that this is an issue known to Kenwood. There is no known fix as they are uncertain as to whether it is a Kenwood or Apple problem. From what I've now read here on Apple Communities I suspect that it's an Apple one.

The retailer also suggested that the forthcoming iOS 11 update (which does include a number of changes in CarPlay) may help. It's not too far away so I'm happy to wait at this stage. I'll try some new cables etc. too but don't hold out any great hope that they will solve it all.

I'm having the exact same issue. I just upgraded to iOS 11 (IPhone 7), and I have a brand new 2018 Audi A3 and the carplay sounds horrible with the USB cable. This is a high quality cable provided by Audi, but it sounds amazing on bluetooth, and horrible on the cable. Can you guys please fix this issue?

I am in the same boat!

BRAND NEW Hyundai iLoad MY18 model... Apple CarPlay in factory head unit!

Phone calls through the USB cable running CarPlay is UNUSABLE!!!

It is quiet... static... and just BAD!!!

One of the reasons I upgraded to the new model iLoad (already had a 2013 model) is to have the CarPlay features...

And well it is CRAP!!!

Apple is losing its quality in EVERYTHING!!!

COME ON APPLE!! RESPOND PLEASE!!!

FIX YOUR S#*T!

I received an interesting piece of information from the Genius Bar tonight and I think it may be the root of all of our problem here. Under Cellular | Cellular Data Options | Enable LTE, there is the choice of Off | Voice & Data | Data Only. My phone was set to Voice & Data and was advised to change that to Data Only should I experience any robot like phone quality. She said it hits iphone 7 and 8's (I assume X as well) especially hard.

So try turning that setting to Data Only and see if the phone quality improves. My initial tests didn't show any robot-ing but I haven't tested it long enough to tell for sure if it solves the issue.

Kenwood DNX-994S with an iPhone 8+

Update: Apple engineering requested logs of this issue which I have uploaded. Hopefully they will have a fix in a future IOS 10 release. I'll provide another update when I hear anything.

Honda Accord 2016, which was working fine in terms of quality of sound during phone calls until approx. the time I upgraded to iOS 10.

I'm having the same issue. Bluetooth music is crystal clear, the second I connect my iPhone 6 to CarPlay with a cable the music soundS horrible. My car being a 2017 VW Passat with OEM MIB II

Yeah, it's pretty pathetic. I have just downloaded iOS 11 so I'm going o see if that helps at all.
