CarPlay iOS17 not working

Okay, so far on iPhone 13 Pro Max after iOS 17, 17.1.2 and 17.2 updates CarPlay doesn't work on 2021 SYNC3 Mustang, 2024 Opel SUV Hybrid in Europe, and on external screen device link with bluetooth. I can pair, verify, load data, but CarPlay never launches on vehicles. The first two say connected the third never indicates it's connected. Tried factory resets on all vehicles and external devices and clearing of CarPlay and Bluetooth Connections on iPhone, but still no CarPlay. Reset iPhone network connections, changed network access setting on iPhone as directed. Literally nothing works. So, I installed my wife's Apple 14 Pro with some version of iOS 16? on it and magically everything works on the same CarPlay devices.

So that essentially proves this is caused by iOS 17. If I had an iOS 16 backup, I'd revert, but unfortunately backup on iOS 16 started failing which is why I upgraded to iOS 17. It appears that Apple stopped testing software before launching, we're all beta testers.

Also have loaded latest firmware multiple times, so that's not the problem either.

I've also tried changing cables but that shouldn't have affected my wireless CapPlay connection device, so still iOS 17 issue.

I literally had to pull up an old iPhone mount and install on the front dash so I can navigator or borrow my wife's phone.

So Apple, please fix defective CarPlay on iOS 17 so we can stop wasting time and drive safety with handsfree.

To thise who have been unsuccessful with “powering off” the Infotainment system:

Did you hold the power off until it asks if you want to reboot?

I don’t believe it will work if you simply power off and power on.

admittedly this is what worked for a Honda. I don’t know about Toyota as it seems this is where most of the posts have come from.

If you need to restart the infotainment system, that proves the issue in your case is not with the iPhone but with your car's infotainment system, and only your auto manufacturer can fix it with a firmware upgrade.

It’s not just cables(I always connect by Bluetooth). I have an Apple 14 and a 2021 F-150 Lariat. Since the latest iOS update, CarPlay does not work properly. The main symptom is that when I turn the truck on, my phone appears to connect okay, but the large panel on the left where my Google map normally is and the upper panel on the right (I never use it but it has something to do with the microphone) show nothing but the Google logo. I then go into my phones Bluetooth settings for the truck, toggle off CarPlay and back on again. This appears to fix the problem, but in Bluetooth settings on my phone my truck still shows not connected, so it’s never connected, but after I do this CarPlay works. I have to do this every time I start my truck. I’ve called Ford 3 times - every time they walk me through a reset procedure that involves opening the door, hitting the lock, closing the door, and repeating a sequence of holding the power button and seek forward buttons until the panel restarts (I think I repeat this four times). It seems to fix the problem until I turn off the truck and restart it.

Basically, as Apple updating their software they start to disregard "older" car models. I was told that by an Apple representative on my call last evening.

However, I got 2 more suggestions:

1. Try connecting another iphone to my car and see if the CarPlay works with that iphone. If it does, then my phone probably got a glitch while updating and may need a full factory reset.
2. If it still doesn't solve the issue, then I may try my car's factory reset.

If nothing works, then basically Apple is saying that my car is too "old" for them to care for.

I have had some mixed progress. I found limited success with turning off my VPN. It’s not intuitive since my connections were Bluetooth or hardwire USB. Some CarPlay devices like Ford Sync and have a conflict with Hardwire USB and Bluetooth. To use their required Hardwire connection, you must not connect Bluetooth at any time. I bought two third party iPlay devices one uses Bluetooth, the other initially connects with Bluetooth and then connects through WIFI. Both of these worked right out of the box with VPN disabled and somehow at least temporarily reset the connection on the Ford and Sony devices. Since the iPlay devices are so easy to use and wireless I don’t use the other devices for anything than music.

No change still trying any listed suggestions. All have failed

Have you tried to reset your car "media" settings (could be "radio", "cable", "media", etc anything that sounds like that)? I posted it a few weeks ago and it was my solution after EVERYTHING else failed.

Thanks. This worked for me in my Renault Koleos. Pressed the on/off button for about 3 seconds and the system reset and started recognising CarPlay again.

not for me :( I was looking forward to it, but it changed nothing.

I just did the 17.3 update and my CarPlay is finally working again. Hopefully all of yours will as well.

I can confirm this works, I’ve been stuck for 2 days, changed cables and tried everything Apple suggested. Just rebooting the infotainment system works on Honda Civic 2019

Update 17.4.1 sorted the issue for me after many months of frustration (Lexus NX & iPhone 13 Pro). Have update 17.5 to install now & im a bit scared.

That's because if it's due to your USB-C cable, they can't do anything about it.

Make sure your cable is a data rated USB-C cable before anything else.

Then make sure you delete your phone from your car and your car from your phone - reset your car's head unit to factory defaults if you've the ability and it's not too big a hassle.

Many have found a good cable in conjunction with creating an all new pairing does the trick.

Restarting the infotainment does the trick, however this was not the case previously on iOS 16.

You shouldn’t need to restart infotainments to get the carplay to work - should just connect and work rather than faff around with the infotainment while driving.

I have an iPhone 13 Pro Max with iOS 17.4. Wireless CarPlay wont re-connect on Hyundai Sonata 2024 each time I start the car. Tried all suggestions available on the web and nothing works.

The only thing I found to be working is to restart the iPhone every time I am in the car.

Software updates such as this do not break older versions of software.

If you have a new car, more features may be available via CarPlay than in older cars or with older head ends (if they cannot be updated) but that in no way means CarPlay stops working in older vehicles.

One of the first troubleshooting steps should be to delete all traces of your current phone from your car head end's memory, and delete all references to your car's connection from your phone, allowing each to make a fresh association.

Finally, always check with your vehicle's maker as many do update their automotive head end systems regularly.

Beyond that, if you have an iPhone 15, you must use a USB-C cable and/or adapter rated to pass data, not just the voltage required to charge your device.
