CarPlay not working with iPhone 16 Pro

I upgraded my iPhone 12 Pro to a 16 Pro, and the new phone will not connect to my 2018 Mazda CX-5 with CarPlay. When I plug it in, it charges but makes no sign of connecting.

iPhone 16 Pro, iOS 18

I am so disappointed! My new iPhone 16 Pro does not work connect to my Carplay in my Toyota CHR. Had I known this, I would have upgraded to an iPhone 15 Pro instead. :(

If you already have a solid data/charge cable that you are certain was working before in your car with a previous iteration of iPhone, it is likely NOT a USB-C type cable, hence the need to attach an adapter to it so that it will be usable with your new iPhone 16 -- which as you properly note ONLY works with USB-C. Many users are buying the Apple USB-C to Lightening Adapter (USB-C to Lightning Adapter - Apple) because their prior phone used a lightening plug that inserted into their phone, with the other end being a USB-B plug that went into the car via (again) a data/charge cable. Using your old cable, you just need to attach this adapter to the old cable and it should work well with your new iPhone. Many users in this thread report doing that and it works totally okay. I'm one of those users. The only other thing I had to do in my vehicle was I did have to reset my car's internal "infotainment" (i.e. entertainment/audio/visual/etc) system again to default settings and set up the phone again as a new device, and then add back all the other car settings that you want. Hope this helps.

Try this:


  1. Go into your iPhones settings and turn off everything related to CarPlay and restart the iPhone.
  2. Do a factory reset on your car's screen.
  3. Go back to the iPhone and reactivate CarPlay.
  4. Back to the car's CarPlay set-up menu: When prompted, select Forget This Device.
  5. Then, re-sync your iPhone to CarPlay.

I had this same problem and doing a "Reset to factory settings" on the car radio is what fixed it for me.

I have three GM vehicles (two 2017 Chevy Cruzes and a 2019 Chevy Traverse) that I had been using with my iPhone XR via CarPlay for years. When I upgraded to an iPhone16 Pro the Traverse and one of the Cruzes worked immediately, but the second Cruze wouldn't recognize the phone via CarPlay no matter what I did. After two days of fiddling I finally did "Reset to factory settings" after which it instantly recognized the new phone.

Yes my Mercedes too only has USB-A inputs thus I had to buy the USB-A to USB-C Adapter from the Apple Store.

USB-C to USB Adapter - Apple. Separately -- I went to my internal Mercedes Infotainment center, and to "Systems" and completely reset the infotainment center to its default settings. Using the same cable (data plus charging) that I knew worked earlier for Apple CarPlay, but now with the new USB-A to USB-C adapter attached, and after having rebooted the infotainment system to default setting then attached my new iPhone 16 Pro to the system and it then did recognize the new phone and I was able to proceed to set up the new phone. The only real downside is that one will need to completely set up all the other in-vehicle settings that one wants inside the vehicle but that only took me just a few minutes to re-establish. I hope this works for you.

OP update (2018 Mazda CX-5). I found that the cable I had borrowed from another device in my home was one of those that provide power but not data.


So CarPlay “works” now. But very oddly. I’ve seen this pattern repeat for the past three days:


  1. Plug it in and nav comes up, but no music. A few seconds later, “mobile device error” pops up on the car and it disconnects.
  2. Unplug/plug it back in. Nav comes up, and music starts playing out of my phone’s speaker instead of the car’s sound system.
  3. Unplug/plug it back in. Nav and music come on, but the music sounds tinny, like I have an old transistor radio sitting on my dash.
  4. Give up and leave it like that. Five minutes into the drive, the music cuts out for 2-3 seconds then resumes using the full sound system. All is fine after that.


It’s so bizarre, and completely repeatable. You would think it would either work or not work.
