Apple CarPlay not working with iPhone 15 (USB-C issue?)

My issue is different than everything I find online. mine works fine with my Sony aftermarket Carplay head unit (XAV-AX210) - but only AFTER the head unit is on and booted up. I can not plug in until after the "beep" of the unit being booted up. Anytime before that and it simply doesn't recognize the phone is plugged in. BUT this was never an issue with my iPhone SE 2nd gen that I had right before the iPhone 15. There are almost zero settings for CarPlay on the phone and I've forgotten the vehicle numerous times and have a different name on my phone than my old phone. Has anyone seen this issue?? Again, it works fine - but only if I plug it in after everything is on. That's not my normal process - I used to get in, plug it in, then turn on the vehicle. By the time I'm ready to take off everything should be up and running - now I have to turn on the vehicle and wait for the head unit to boot up before I can plug in and get started. It's crazy and makes no sense.

After spending and hour and a half in the car I was told that I had to go to the dealership to update my 2017 Buick envisions firmware to enable CarPlay with the iPhone 15. I did, paid $215 and four hours later with four Buick advisers, Onstar and Apple it still doesn’t work.

i phoned apple today to speak with a Tier one person who after asking me if I did this, did I do that told me that Apple is aware of the problem and their engineers are working it. But it’s important that people let them know of their particular issue.

so basically we are the Guinea pigs for the Apple engineers and doing their troubleshooting for them. They’ve known of this issue since November 2023 and they are still selling iPhone 15s without a resolution.

shame on Apple.

Same problem, wired connection in a 2020 subaru, i have a iphone pro max 15 and Carplay won't recognize the phone

Be sure to tell Apple about it, either by contacting Apple Support directly:

Contact - Official Apple Support

or by leaving feedback:

Feedback - iPhone - Apple

Did you buy a cable which is data and charge capable and is MFi (made for iPhone)? Not all cables are.

Check to see what order in which you are seeing posts.

There is an option near the top of the web page to change ordering:



Done, thanks for the links.

Lobster great advice. You should work for GM or apple. I called both and neither didn’t have any idea how to fix it.

Great Job!

I'm glad it was helpful!

Did you read the advice I offered another poster above?

Agreed. Happy for MC10M, but both my OEM and Anker cable only connect after numerous attempts. My 15 Pro never overheated, that doesn’t mean the there wasn’t a problem.

Thank you for coming back and letting us know things are now working and that we helped you!

VPN is simply the worst thing you can have an iPhone. Don't just turn it off, REMOVE it. VPN causes all sorts of issues on iPhone and is simply not needed or helpful.

You must have slept at a Holiday Inn Express (old commercial);-) I don't know what else to suggest. It's working great in my 2023 Genesis.

Absolutely, even after 17.1 it intermittently works. Plug in, plug out, plug in plug out 🔌. It will eventually connect, and work. But this has to be an iOS issue.

regards.
