Took my Skoda Fabia into the dealership today for another issue and asked them to update the firmware of the head unit and it resolved the issue. Skoda know and there is a TPI out so it’s covered by warranty.


Anyone who tells you to change cables or changing anything on your phone is a moron. It has nothing to do with your phone but with your head unit.


head unit software version is now 8755. It works. Finally.

This actually makes a lot of sense.


Streaming relies upon a constant solid data connection which is the opposite of what a mobile data connection is.


If the next block of data for your song comes in a few milliseconds too late for smooth playback, what is the audio codec supposed to do?


Yet if the playback software buffers too much to avoid this, you’re left waiting for seconds before your song starts playing.


Perhaps their audio player needs to put up a spinning “buffering” cursor like you get on YouTube whenever this occurs.

Just a reminder - by saying "Apple, sort it out" here you are literally talking into the wind.


No one from Apple Engineering reads these forums, we are just other Apple users here.


You can contact Apple in either of these ways:



Note also if it's a Pioneer or other third party company issue, Apple isn't going to break iOS to make it compatible with their products.

It sounds like my issue is slightly different to others in this thread, butI think it must be related nonetheless.


I purchased my car (2016 Peugeot 208) last September, and since then I’ve noticed that any kind of audio played through Apple CarPlay via the USB connection (it doesn’t support wireless CarPlay), skips / stutters every 2-3 minutes. Playing audio through the radio and Bluetooth is absolutely fine, so this made me realise that it must be a CarPlay problem.


I initially decided to ignore it but a few months ago I’d had enough and decided to take the car to a Peugeot dealership to see if there was anything that could be done. They updated the car’s infotainment system software to its latest version and claimed that this had fixed the issue. 2 minutes after testing in my car, I could clearly tell that the problem was still there.


This prompted me to think that the problem could be to do with the actual USB port in my car, as I had already tested the issue with multiple different phones and cables. I therefore took my car back to the dealership and got them to replace the USB port. Again they claimed that this had fixed the issue, but it was clear as soon as I had been driving for about 2 minutes that the problem wasn’t fixed.


Finally I took my car to a different dealership to see if there was anything they could do, however after testing themselves while I was away, they said that they couldn’t notice any problems and that it must be an issue with Apple. Unsurprisingly about 2 minutes after driving my car afterwards, I could notice the problem was still there.


I’ve spent too much time, money and energy getting Peugeot dealers to look into this, and it’s clear that it isn’t in their interest to try and fix it. I have since tried all the steps mentioned recently in this thread (changing phone’s Apple Music settings to High Efficiency Audio, changing EQ settings, turning off Sound Check etc.) but this hasn’t fixed anything. The problem isn’t with Apple Music as the problem still persists when listening to podcasts, talking on the phone, when Siri is reading things out etc.


I honestly don’t think it’s a problem with the car, and the issues others have been facing have been similar to mine. I think it must be something to do with my phone’s IOS, as I haven’t been able to test my car with any IOS older than last September (when I bought the car).


If anyone has any advice or suggestions to help, that would be much appreciated. I spend around 5 hours a week in my car and as an avid music fan, this problem drives me insane. Hopefully Apple address this soon.

Very interesting. I've gone back to the theory that it could be a problem with the infotainment system in my Peugeot 208 - with every car I've been in recently I tried using my phone with CarPlay, and they all worked perfectly. I've finally convinced the dealership to order me a whole new infotainment system after a lot of back and forth, and it arrives at the beginning of July when they'll install it. I'll post an update here once it's been installed and see what happens.

I’ve had the same experience. The Waze app has had known issues in the past with CarPlay and playback volume/quality. So I think this is the most plausible cause for those who have updated the head unit to the latest software, but are still experiencing playback issues. It’s on the dev’s of these navigation apps and Apple to come up with the solution at this point

I have the same issue in my BRAND NEW 2021 Ram 1500. The issue is exactly as described in this thread. Its fine at the beginning but once it gets the first *crackle* around 5-10 minutes into the drive, it becomes a constant nagging presence until I unplug my phone. Even when I unplug my phone, it just comes back again 5-10 minutes later. I've replaced the cord twice, tried different usb/ usb-c ports, updated my phone, restarted my phone. Nothing works. It 100% has to be a software problem and I think the others in this thread can agree. It makes Carplay unusable. Its a nuisance that makes this wonderful feature useless.


Apple.. Please fix this issue! IOS 15 came out recently with no mention of a fix on this bug. We don't need fancy maps or other novelty features. We need reliable function of your most commonly used offerings. Carplay being one of them. Please fix this issue this so I can start using Carplay again.
