CAR Play Issues after IOS15 Update Cannot Load SiriusXM Or Amazon Music

Found a solution on Reddit that worked for me. Disable/turn off EQ in Settings>Music. I had a 12 pro with equilizer enabled and it worked fine even w IOS 15. However, the new 13 pro max would not play any music apps on Carplay until the EQ was turned off. Hope this helps others. 2021 Honda Accord wireless carplay and 13 pro max. Such a random setting...I would have never found it.

Hi FPGFHFMA,

We see after updating your iPhone to iOS 15, CarPlay no longer works properly with Sirius XM or Amazon Music.

As the iPhone has been recently updated, do you also have any updates for those specific apps in the App Store?

• How to manually update apps on your Apple device

Additionally, as CarPlay interfaces with both your iPhone and the CarPlay software in your receiver, it is possible the Alpine unit may need an update for iOS 15. If the issue persists after updating the relevant apps on your iPhone, we'd recommend reaching out to Alpine for assistance in updating the firmware of the CarPlay compatible receiver if need be, or confirm its compatibility with iOS 15.

• Alpine Support

Take care.

Based on what app developers have said (see my post earlier in this thread) I don't believe this will be fixed with an iOS update, but rather with individual app updates.

Apple made an entitlement used by CarPlay obsolete in iOS 15, so apps that use that entitlement no longer work. There is a new entitlement, but it requires Apple to grant use of that entitlement. At least according to developers Apple has been slow to grant use, so several apps have been left broken while they wait. Look up @downcastapp on Twitter for a better explanation. They are one of the apps that stopped working in CarPlay.

I expect all these apps will eventually release updates that will fix the issue, but in the meantime there doesn't seem to be a workaround.

It's been fixed in 15.0.2. Just released today.

Go to this Apple Thread regarding USB audio not working in IOS 15. Search USB AUDIO Support in IOS 15.

Disable your EQ. If already disabled, enable it and set EQ to any profile and disable it again.

if that doesn't work, reset ALL settings.

Do these steps on your iPhone ofcourse. This should solve 99.9% of the problems here. Please mark as helpful/solution if it worked, so others see it.

I turned off the equalizer in Music and Carplay works for music again. I then tried other equalizer settings and it still works but not Late Night. If I switch to that one, it boots me out of Carplay.

This is according to the developers of Downcast, another podcast app that is not working in CarPlay on iOS 15. I expect many other apps are experiencing the same issue:

"Many audio apps still use the com.appledeveloper.playable-content` entitlement, which allows you to provide metadata that CarPlay uses to generate the UI for your audio app. That was deprecated in iOS 15 and, apparently, obsoleted as well. A newer/better method of generating a UI in CarPlay was introduced in iOS 14. It requires a new entitlement: com.appledeveloper.carplay-audio`. Despite both entitlements being for audio apps, the new one isn’t automatically assigned to apps that already had access to the older one. Developers of such apps must request access to the new entitlement. While we did this some time ago, Apple has yet to respond. While the app has already been updated to use the new CarPlay framework, it can’t be tested on a device or submitted for review until Apple grants us access to the new entitlement. As soon as that happens, we’ll get the update out as quickly as possible."

Shoesstriss: You would think huh??

You would have thought this would have been caught during the beta testing. It’s hard to imagine that not a few of the beta testers have CarPlay and stumbled across this issue.

As I mentioned, I rolled back to 14.8 and no issues with CarPlay, everything loads as it should …the only issue I have is my watch and phone don’t talk to each other now but I can live with that for now.

Try a forced restart.

• Press and quickly release the volume up button

• Press and quickly release the volume down button

• Press and hold the side button.

• When the Apple logo appears, release the button.

Here's an article from MacRumors that lists the fixes.

It’s 15.0.2 and it’s already out. Actually we are already at 15.1 now. Go to settings and software update. Should come up for download.

I don’t believe the failure to load the said apps (Sirius , Audacy , etc) are the CarPlay unit’s fault (ie alpine or other cars). I am having issues including that of the Apple Music. When I updated my iphoneX to iOS 15 CarPlay in my 2015 Audi and 2018 Hyundai worked just fine. When I purchased the new Iphone13 with the updated Ios15 - Apple Music would make the CarPlay disconnect as soon as I press play. Sirius Xm, Audacy, pandora , iHeart Radio all simply won’t load up-But- it does on the phone itself. You can select the station/ music on the iPhone but cannot control or load up menus on CarPlay. After reading through numerous post, someone advised to turn Off EQ on IPhone under - Setting- Music- EQ (select none) and that made Apple Music respond on CarPlay with no problem. And no disconnect. HOWEVER, that didn’t fix Sirius Xm app or other music stream apps to load up on CarPlay. Something in the IPhone13 settings is preventing it to do so. APPLE SUPPORT needs a better response or totally dive into this issue as I strongly believe it’s within the phone’s settings not necessarily updating the CarPlay module in each car.

Clearly an IOS15 issue. My phone worked fine minutes prior to the upgrade. Post upgrade it doesn’t. It doesn’t work in a Ford Escape, a Thor Motorhome, on a Kenwood receiver, a JVS receiver or a Chevy Silverado or a Chevy Equinox. My wife’s phone, unupgraded still works fine. Issues are loss of connectivity for no reason to CarPlay. Calls switching to the blue tooth connection on the radio but with no audio for no reason. Have to unplug and replug the cable to get it back. Maps loses connectivity. Numerous audio apps like audible, Spotify have issues as well. ALL radios will report something like “error connecting to USB device”. Have also tried multiple cables, and confirmed unupgraded phones work fine on these cables. So telling everyone it isn’t your problem isn’t going to fly.

Please fix your software and issue an update asap.
