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 have been unable to make phone calls after upgrading to iPhone 16 Pro Max. Maps and everything else works with CarPlay. Audio crackles, has static and drops every other word. I have a Toyota Sienna and I have done everything  everyone has suggested, to no avail. I have checked  Privacy/Content, new cords (from Apple and Amazon), uninstalled my phone from my Toyota and reinstalled it. I STILL cannot use my phone with CarPlay to make calls. If I do, all of the above happens, and worse yet, CarPlay won’t let me disconnect the call. The red disconnect button on CarPlay is frozen and when it finally disconnects on its own it randomly dials someone on my favorites list. Any additional suggestions will be greatly appreciated. Apple Support has poorly addressed at this entire debacle with CarPlay and I’m not sure, after this mess, that I will continue to be an Apple customer. Their support on this, and other products I have, has fallen way below par in the past year. They are not the company they used to be.

I think I figured out where my issue is with CarPlay not working. I use WiFi for my CarPlay connection and the iPhone seems to disconnect from the WiFi since there isn’t data. If I keep my phone open to settings, and then once the CarPlay disconnects, I can manually select that WiFi network again and the CarPlay immediately reconnects and works for another 5 minutes.


The same issue is true for another device I own that uses a WiFi network to function but doesn’t have data. It’s like the iPhone senses that there isn’t data and then tries to change to another WiFi network or decides to use cellular, which is weird since I am actively having input from this network (it’s a medical device camera that is giving a video to my phone). I have to forget the regular WiFi networks that are also there so my phone doesn’t try to change over to them.


For me, it seems like some type of WiFi system setting on the iPhone 16 that is causing the CarPlay problems.

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.

It sounds frustrating! Since your iPhone charges but doesn't connect to CarPlay, try these steps:

  1. Check for Updates: Ensure both your iPhone and your Mazda's infotainment system have the latest software updates.
  2. Try a Different Cable: Sometimes, a different USB cable solves connectivity issues, especially if the original cable shows wear.
  3. Enable CarPlay: Go to Settings > General > CarPlay on your iPhone to see if your Mazda appears on the list. If not, reset CarPlay settings.
  4. Restart Both Devices: Reboot your iPhone and turn your car's system off and on.

If none of these work, Mazda support might have specific troubleshooting steps.

My new iPhone 16 worked perfectly on a newer rental car. Will not work on our 2020 Tundra or 2020 Telluride. Would not be recognized by my iMac. Spent hours trying to figure this out. Used cable that came with the new phone. Used multiple different cables. Spent hours on the phone with Apple and actually scheduled an appointment with Toyota. I had a little epiphany(wife suggested), I tried this little adapter and it’s worked perfectly with my computer and on the car.


I used a USB-C to USB-C cable with a small adapter from USB-C to USB. Seemed like a cheap hack.

I have a RAV4 and recently upgraded to an iPhone 16 with IOS 18.1.1 and was having the same issue. I tried some of the suggestions here with phone settings but decided to go with a data transfer and charging cord and it worked immediately. I got this one at Walmart for $6 rather than paying ridiculous Apple prices for one. This was in the auto section so it’s obviously an issue. Whatever cord you buy, be sure it doesn’t just charge but also transfers data. That seems to be the key. I’m guessing USB-C cords don’t automatically do both like lightening cords. I wonder how many landfills are polluted with old cords because Apple and other electronic companies want to find ways to make more money by creating new cords and charging a fortune for them. Does Apple claim to be an environmentally friendly company? I hope not.
