CarPlay Not Working for Some iPhone 15 Users, Possibly Because of USB-C Cables

CarPlay is not working as expected for some iPhone 15 users, an issue that is likely linked to the transition to USB-C. There are multiple complaints from MacRumors readers and Reddit users who are unable to get ‌CarPlay‌ to work with their new devices.

CarPlay SharePlay
Cable type and available port options are a common theme in the ‌CarPlay‌ reports, with many of the functionality problems linked to USB-A to USB-C cables. Many cars, even some that are more recent, have only USB-A ports and not USB-C ports, so a USB-A to USB-C cable is required.

Unfortunately, it appears that not all USB-A to USB-C cables on the market will work, and some that work in certain vehicles will not work in others. A Reddit user explains:

I got in my car this morning and plugged my phone in with a USB-A to USB-C cord in order to use Carplay, and found it does not connect. It charges, but no Carplay. In my Carplay settings on my phone, it says the name of my car as if it were connected, but nothing shows up on the screen.

I work at a dealership so I tried it in a bunch of different cars and nothing worked. My car doesn't have any USB-C ports, so I tried the Apple-supplied C to C cable in a 2023 model and it worked no problem. So it seems that either USB-A to USB-C does not allow Carplay, or it simply does not work anymore with non-Apple chargers.

Other ‌CarPlay‌ users chimed in and mentioned having the same problems, though some were able to get ‌CarPlay‌ to work with USB-A to USB-C cables like those from Belkin. Several people had success getting ‌CarPlay‌ working with a USB-A port using Belkin's BoostCharge USB-A to USB-C cable, but others had no luck.

Having tried 2 good quality cables I called Apple Support about this. They proceeded through various potential remedies which didn't work. The call ended with me agreeing to try the cable supplied with the phone, after getting a suitable adaptor. When I got home I tried 4 more cables. 3 of them worked, these being ones from Sony, Samsung and Nintendo (I think). Today I tried the Apple cable + adaptor and that works as well. The good quality cables (3 of) all previously gave me no problems, mainly charging but also a high speed PC to VR headset connection. iPhone to Windows PC connection worked fine with one of them (I could connect to my phone in iTunes). I suspect that there is a specification point that the 3 "good quality" cables have missed. If so, I don't know if it is the car or the iPhone that is particular about this spec. point!

Trying a variety of cables, specifically those from known brands and with data transfer support, seems to be the best way to get ‌CarPlay‌ to work, but it is worth noting that some people have not been able to get ‌iPhone 15‌ ‌CarPlay‌ to work even with Apple's adapters and cables. From Reddit:

I have the exact same problem. Have tried (and bought) several different high quality cables, nothing works. Been through all the troubleshooting scripts and AppleCare+. Seems like either an iPhone 15 or an iOS 17 problem.

One MacRumors reader that contacted us said that the issue had been reported to Apple and that Apple is working on a fix for the problem. Apple could perhaps implement a software update that improves compatibility with some cables, or the company could better explain which USB-C cables will work with the new iPhones.

While most of the complaints have been from car owners who are limited to USB-A connection ports, there are also reports from some who have vehicles with USB-C ports and even some complaints about wireless ‌CarPlay‌. One MacRumors thread suggests that VPNs may be responsible for some recent connection issues, though turning off a VPN did not work for all users.

Oy, I just went to my car to check and am having the same issue. If a VPN is activated when the car starts, the car will not pick up CarPlay at all. If the VPN is disabled, CarPlay starts, then if I turn the VPN back on CarPlay crashes.

With the wide range of reports, there appear to be multiple ‌CarPlay‌ issues at the current time. ‌CarPlay‌ users may need to transition to different cables, but Apple may need to release a software update to solve some of the ‌CarPlay‌ problems.

Maybe with certain cables the iPhone is trying to charge the car battery ?

The old USB A-to-C cable that I got from IKEA several years ago works just fine for CarPlay in my 2018 Chevy Volt. What kind of janky cable is everyone else using?

It's not just iPhone 15 users. I have an iPhone 12 Pro Max and it's a mess right now after the iOS 17 upgrade. Siri is sending duplicate texts and continues to listen when she talks, then she texts what she said back to you. Example:

Butler Trumpet: "I'm on my way home from work"
Siri: "Sending I'm on my way home from work"

The text arrives to the recipient and they get two separate texts "I'm on my way home from work" and "Sending I'm on my way home from work"

Another time this happened:

Butler Trumpet: "I'm on my way home from work"
Siri: "Here's what I heard "I'm on my way home from work" Do you want to send it or change it?"
Butler Trumpet: "Send it"

The recipient got one text that said "Here's what I heard I'm on my way home from work do you want to send it or change it? Send it"

You're drunk Siri. Go home!
