Crackle and Pop using CarPlay

I am having an issue with audio quality when using CarPlay. This issue affects playback using both iTunes and the Podcast app. Every 3 - 15 minutes the audio will skip for about half a second and very often, but not always, comes back highly distorted with crackling and popping. Very occasionally it will skip and not experience an audio drop.


The only work around I have found is to either turn off the car and restart it, or unplug the phone from the USB and re-plug it. This works until the next skip, which are occurring more frequently in recent days.


Switching to a different podcast or album results in a clean signal until another skip occurs. Switching from an affected podcast or album to a clean one, then back again, does not fix the issue. Once corrupted the audio remains corrupted until the phone is disconnected then reconnected.


I have tried the following with no success -

  • Rebooting the phone
  • Using a new lightning cable

iPhone 6s, iOS 11.3

SOLVED!!!


Hello everyone. First of all I wanna say I’m sorry about any English mistakes. I am Brazilian so not a native speaker.


I was having the same crackling and popping problem with an iPhone X in a Mercedes Benz A200. My first guess it was a hardware issue, so I got to an authorized apple dealer and asked for warranty. They exchanged instantly for a new iPhone. The phone was working fine when I have installed as a new iPhone, but when I reseted and installed from a iCloud backup the crackling came back, what made me suspicious the problem was a software and not hardware problem. I got in touch with apple support by phone and dozens of tests were made. We got to the conclusion that the issue was some corrupted file in my backup, so I have backed up my photos, contacts and notes in iCloud once again, reseted the iPhone and installed as a new iPhone logged to my iCloud account. This way, I lost every files and settings I had but manteined the photos, notes and contact (they automatically download once you log in iCloud). I did this 3 days ago and didn’t have the problem one single time yet!!! Hope work for you guys too!!


Regards fom Brazil,


Raphael Freitas

Called Apple support again referencing existing cases and creating a new one. They 100% assure me they are aware and working on the issue however have no ETA. Advised that 12.0 and bet as in between haven’t resolved the issue.


Not sure there’s much else we can do but keep bugging them to fix their bugs.


You would think with a Trillion Dollar company they could quite easily isolate this in the car models mentioned. The Hyundai Tucson has been brought up at least half a dozen times in here. I shouldn't have to go to a car yard and start fiddling with another car similar to mine, afterall they have now been replaced with the 2019 models. Surely it's easier for them to get a loan car from Hyundai or even rent one with the same specs.


I have documented this to Apple

Supplied Video of the fault, in fact multiple videos of different iPhones

Have tried different USB cables

Have tried Phone reset on multiple iPhones

Have tried Software Upgrade on both iPhone and Carplay Head Unit fitted to my Hyundai Tucson

Have supplied log files of phone to Apple Engineers

Have had contact with Apple Support personnel nearly every day about the problem.


I'm not going to a Hyundai dealership and walking around asking for a 2018 Hyundai Tucson to test if that car has the same problem as well. We already know it will from the responses in here. I think I have done enough, and provided enough evidence for Apple to get off their backsides and investigate it themselves.


Right now I am pondering whether to upgrade my iPhone X to a iPhone XS Max. This problem is making me reconsider my choices, and perhaps buying a Samsung Note 9, Google Pixel 3 or a 1 Plus 6T.


Android Auto works perfectly fine. If they can get such a small program working with the fragmentation issues Apple claims they have, then why does Apple have so much trouble? I don't need silly Memoji's on my phone, but I do need Apple Carplay.

Come on. What is the problem with Apple nowadays? I m having the same problem in Brazil with a Mercedes-Benz A200 2018. I even took my phone to an authorized apple dealer with a video of the problem. They instantly exchanged my iPhone X for a new one which was worked fine when I seted up as new iPhone, but when I restarted and chosen to install from a iCloud backup, the problem came back. It’s obviously a software problem. I know a friend who has a Jeep Compass and have no problem at all. If you reset your phone and chose to setup as a new phone, I may think it’s some kind of app doing the interference. What the problem apple?

It's amazing that Apple can't solve a problem like that. They blame the car radio.. A problem that not even an IPhone 6 has.. I wonder if even the new Xs we have the same problem


All iPhones suffer the same problem. If yours doesn't then I suggest you have a different problem or maybe an iOS that is not affected like below 11.3


I have personally tested iPhone 5s, iPhone 6, iPhone 7, iPhone 7 Plus and iPhone X. All running iOS 11.4.1 and above. If you think you have the same issue then contact Apple Support so you can talk to someone there and help resolve it. No-one here on this forum from Apple will solve it for you as they don't respond to this thread.


Just FYI, I can tell you it will sound similar to having a bad sound driver installed in windows where the codecs don't work properly, so you get some popping, clicking etc.


This problem will persist in CarPlay, iTunes, Music, Youtube, Spotify.

Out of interest, has anyone purchased the nw iPhone Xs or Xs Max and tried it in their vehicle which had the issue with iPhone 6 to iPhone X? Logically it would be the same but I am curious.

Not willing to spend $1800 upwards on a phone that is going to crackle and pop when I listen to music. I'm giving Apple a chance to resolve this issue first before I do anything.

Been dealing with this issue on my 18' Subaru Crosstrek for almost a year. iPhone 7, ios 12.1.2, Apple lightning cable, firmware Rel2.17.43.20. I get horrible crackling noises after about 10 minutes of playing from the phones music library and it only gets worse to the point where I have to unplug it in favor of Bluetooth which takes a few minutes of playback itself to clear itself of any remaining audio distortion until it's perfectly clear again. No issues at all if just using Bluetooth from the start.


Very frustrating as Sirius was not an option on the factory radios in 18 which is why I want to use CarPlay.

Apple Support finally got back to me after a long hiatus. They asked me if I had managed to hear about or find a fix for the problem. I have installed the firmware that is going around currently on this and other forum sites and it does appear ro fix the issue for the people with Cartronics TL-01 head units.


Unfortunately Apple's communication with me was pretty poor to useless in the last 2 months, and because of this I told the person from support that my family, except 1 member, had changed over to Android. Samsung, Oppo etc gained 5 new sales from Smartphones and watches. I may go back to Apple in 12-18 months time but for now I am happy that I had music working throughout all this problem without the clip clopping noises.


Good to see a fix was eventually found for the rest of you. Kudos to those that didn't sit back and just let this blow away.

Me too having the same problem with my 2017 Hyundai Tucson. I have an iPhone 7plus with latest update. Been to the dealer twice and updated the firmware in the cars radio, issue still continues. Each time they just shrug their shoulders and say it’s an Apple issue. Tempted to go to consumer affairs with this. You pay good money for a car and it’s not up to par.


As far as I see it I didn’t buy the car from Apple I bought it from Hyundai. The blame game is not my concern.
