Wired CarPlay won't connect iPhone 17 Pro Max after iOS 26 update

After 8, yes 8 cords I went onto this forum to find answers. And another guy said he had the same thing along with like 250 other ppl, lol, and he found a cord, Morphie. It is absolutely the ONLY one that finally worked. Others worked for like 2-5 days and then started acting up. I personally also didn’t download or pair my phone with car ( Subaru 2020 Forester) bc I noticed with the other cords as soon as I introduced my headphones into car, it got all confused. I should try but I was just so grateful I got a consistent connection that I didn’t want to mess with it. With that said, if I plug my phone in and start asking to do things too fast like my Tidal music or Maps it has stalled. Always give it 30 seconds to kinda acknowledge the cord and then after that you’re golden. I was Devastated for 2 months not fining an answer. When I did, I bought 4 cords, lol

Thank you soooo much ! The mophie usb c to a was the only cable to connect to my apple carplay (I have a 2019 Honda civic ex-T) and for some reason my iPhone 17 pro max that I just got wouldn’t connect. I tried everything apple support, Honda, google, Reddit. And this is the only comment that helped me.

Resetting the network settings will affect the wired connection as well. It's worth a try.

My current car doesn't have wireless CarPlay. I bought a wireless CarPlay adapter from Amazon and it works great.

Once every couple of months it will hang up, but unplugging it and plugging it back in clears that up. It consistently happens in the same areas, so I suspect RF interference from something in that area is to blame.

Chevy Colorado 2019, same issue. (almost)

My "old" 16 Pro Max still conencts,... and works as it should. Using the same iOS 26.0 / 26.01. 16 Pro Max works, 17 not connecting at all.

iPhone 17 Pro Max, refuse to connect data, only charge.

No VPN

Network settings reset

Car infotainment box reset

Hard resets of device

Different cables

Removed Carplay connection profile from vehicle

nothing seems to work.

The Chevrolet infotainment system cannot be updated, but this should not be neccessary since 16 Pro Max (and 14 and 13) works perfectly fine. Since Apple has not said anything about wired CarPlay being restricted on 17 Pro Max, I am confident a fix will be made... just hope it happens soon - I need it for navigation and messages whilst on the road.

The only thing I did noticed, was that buy default the new 17 Pro Max had "Ask for New" under Wired Accessories the first time I tried connecting it. iPhone 16 Pro Max had "Always" -

In the Car infotainment settings I did see the device show briefly less than half a second. After that - no signs of it. Of course I changed the settings to "Always Allow" and of course I try connect with phone unlocked. and yes, I have forced rebooted a few times.

Yes - I have also tried to factory reset the phone - did not help

I might have to return this iPhone to Apple if not resolvable.

Called support - they did the same as me, googled and saw what other users suggested. So either support also don't know, or - they don't want to deal with it.

Seeing how many reports of this same issue on the internet is troublesome.

No, under the circumstances I would NOT assume the issue isn’t with the car. Is there a firmware update available for the car?

For me this also resolved my issue. I used the cable that was supplied with my iPhone 17 Pro in the box.

I’ve been having the same problem, there is definitely a bug in iOS26 that is preventing data transfer via the USB-C port. It’s impacted my iPad, my 5 month old phone twice (including 3 weeks after having the hardware replaced,) a new phone to replace the 5 month old phone within 3 days… it’s been a saga. I’ve spoken to about 6 engineers about it and at this point everyone is fairly convinced there’s a software bug.

Check with Ford if it needs an update.

Test a phone that still has ios18 if a friend has one.

It’s worth a shot! I actually had a USB-A /C cable that actually worked once I updated CarPlay on my car & CarPlay settings on my phone. It only works on my main USB port under my dash. However, I wanted to use my new C to C cables so I purchased USB-A to C adaptors on Amazon so I could use the C/C cables. They’re inexpensive so you wouldn’t be out much if it doesn’t work. You put the adaptor in your USB port & it converts to C. The cable that came with my phone & another C-C cable I have work good on them. There’s particular brands that call out CarPlay so you can search that but others will work also. They were $6 each at my auto store nearby but Amazon had better deals & I needed more than one. They delivered the next day

I disconnected phone from Bluetooth on 2020 vehicle and I’ve had no more issues so far.

Have you successfully used the same cable previously to connect the phone to the car? Many USB A-C cables are charge only and do not carry data.

Also, if there is a reset button on the head unit, press it to reset the system (you shouldn't lose anything like presets.

I am experiencing problems as well. I have a 2021 jeep and when I purchased the iPhone 17 pro, my wired CarPlay stopped working. I first contacted Apple support and they stated the diagnosis tests were fine. They did encouraged me to call uconnect to see if it’s an issue on their end. I’ve checked to see if I needed any software updates on my car system but, apparently it’s up to date. I’ve also erased any memory of my phone on the system, as well as, all uconnect connections on my phone. Unfortunately, it is not a uconnect problem. It is in fact a problem with iOS 26. I use CarPlay every day to navigate. Now, I have to look down on my phone for directions which is completely unsafe. I love everything about this phone but, if I knew CarPlay would no longer work, I would have NEVER purchased this phone.

Hi, for those people who are using wired, go to your carplay settings in your phone. Tap smartdisplay link something then choose forget this network. After that, reset the network settings of your phone. Wired carplay should be working after that.

I went thru a lot as well. Eventually it came down to having to use the USB. My Nissan has multiple USB ports. I purchased some USB to C adapters on Amazon. If you add CarPlay to your search, particular ones say works well with CarPlay. I think the ones I got were sold by Basesailor. The Apple cable that comes with the phone works on that & I also use braided Belkin C. Though I have multiple USB’s in my car, carplay only works on the main one under my dash. I did the remove the phone & forget this car but that didn’t work at all. I also updated CarPlay on my phone info & updated the Nissan CarPlay. Seems to work fine now but only on the main USB

Not one person has mentioned to update Google maps! This just happened to me and after five minutes of doing the things other people mentioned I checked if an updated needed to be downloaded and boom! It's working now
