iOS 15.1 broke connectivity to my car stereo

No one’s trying to belittle or bully anyone.

I have a 2011 Toyota and a 13 Pro Max running iOS 15.1 that works perfectly with USB audio, so your list of vehicles is in no way all-inclusive.

I’ve also tested on a friend’s Mercedes and another Toyota, also with no issues, nor are there any with home stereo equipment from Denon or a 24 channel mixing board made by Mackie.

You list a wide variety of auto manufacturers, but this issue is not even universal among all of their models and head end units.

Remember also that this is not a place to “vent” - social media and other websites are for that. This forum is for people to ask technical questions which are then answered by other Apple users.

The correct approach is one I have advised in multiple responses; if you are seeing this issue, contact Apple Support directly:

Contact - Official Apple Support

I own an Opel Astra GTC 2013. A few minutes ago, I called to support and the girl on other side tells me that I should update my stereo. I told her that I can’t update stereo in 8 years old car (cd400). Then she told me that she can’t help me, and I can write to apple.com/feedback. I think this is ridiculous. Almost a month we have that issue, but they told same sings that in october.

Hey all I brought a lighting aux cord for the aux port, it does allow you to listen to music and hear navigation but it does not charge and you have to change your by the phone only; does not have a great sound and you have turned up really loud to hear certain songs. Still sucks that our features are not available or accommodating

I have a 2015 chevy Cruze and once I updated my iPhone to iOS 15.1 it will no longer connect to my car stereo via USB cord. It was working fine right until I updated. I hope it’s a big and apple gets it fixed soon. The radio has to many commercials and such. I like it better commercial free

I have the exact same issue. I was able to connect my iPhone via USB port to my 2012 Holden Cruze and play music, now that I have updated to iOS 15.1 it no longer allows me to do it. My partner hasn’t updated his phone, and he is still able to connect.

Just got off the phone with support: 

They mentioned that iOS 15 does not support connecting through the dock with some GM models. They provided the car manual to update the software. To update the software, you have to go to a dealership and get it done by them. My local dealership was charging me $188 for this and they mentioned it might not fix the issue. I declined. Not spending $188 for a **** software update when it should be FREE but thats a GM issue. 

The owners manual suggested to reset radio settings to factory default. I did that and still did not work. I am not willing to pull out the fuse cause I dont think its going to work as my sisters iPhone X running iOS 14.8 still plays music properly. 

As a former Apple technician, I ALWAYS wait before updating iOS cause there are ALWAYS issues. I monitor websites to make sure that those issues have been fixed and I was unaware that this was happening to GM cars at the time. When I updated to iOS 15.1 the next day they stopped signing downgrades to iOS 15.0.2 and now I am stuck on 15.1.1. 

This absolutely ***** and might or might not be fixed by Apple. Apple has a habit of doing dumb stuff like this and I dont get it and thats why I ALWAYS wait for a stable version of the latest iOS before updating. I dont know why they have to removefunctionality in the software instead of just adding functionality. 

Anyways, the only choice many of us have is to keep complaining to Apple Support and constantly escalating it. Remember, those technicians are here to help you but at the same time, getting a new infotainment center and getting a new car are unacceptable answers by anyone and especially a technician. 

Only option we have now is to wait for future updates and hope it solves them.

I will update if I find another solution.

I’m having the same issue. It worked fine yesterday I upgraded and now it doesn’t work at all to play music. The car can’t even detect the USB port with my phone in it. I also have a Chevy Cruz. A 2015. I’m gonna see if I can Google how to downgrade

I figured it out with a '20 Subaru Outback with factory head unit. CarPlay worked with the USB cable plugged in. Unplugged the cable to establish BlueTooth connectivity. I had to delete my iPhone from the car and delete the car from my iPhone in BlueTooth settings. Then I had to add the iPhone back to the car and reestablish connectivity with the car in the iPhone. Basically, delete all BlueTooth connections between the car and the phone and start from scratch.

IT dinosaurs are already acquaint with this "reset that solves" solution (but not). It was a jokes years ago, so-called "Microsoft solution". All my respect for anyone who thinks otherwise, or get success. But I think we shouldn't waste our time trying solving a problem created by Apple. Our case results from an intentional modification in this feature, probably a technological evolution that cause old hardware stop working to force consumer to buy something newer (and all Apple's users knows what I'm talking about). In this case, they did it without anounce, and they didn't expect the impact will be so great. Now let's pray to new iOS release reverses what they did.

following…..because i’m having the same issue. hope this is fixed soon.

Apple only very rarely acknowledges issues; instead they mention in the release notes when an issue has been fixed.

...Anyone willing to Verify turning off the bluetooth thats already upgraded with broken connectivity??

..I downgraded to get mine to work..it was not easy to do...

Have you done a full pull the fuse for 30 minutes factory reset of your car radio?

I also have a 2015 Chevy Cruze and since the update can not connect my phone. I have also changed cords an no app or website will work. I’m beyond frustrated.

There is a fix above if you have iTunes but if you don’t have a look here
