CarPlay not working after iOS 16.5 Update

Verify the infotainment firmware is current, and then contact Mercedes Benz. Again, even assuming this is an Apple issue — which is not certain — Mercedes Benz is still in the best position to isolate and identify what happened here, and to then work with Apple toward resolution.

Whether it's iOS or not isnt necessarily the issue. Honda is the one who made the infotainment system in your car and Honda needs to ensure it works with iOS. Perhaps Apple changed something. They provided the API to Honda in advance of an update. And Honda is the only one who can update their infotainment system in a Honda car. Apple has no control over Honda software at all.

Or the manufacturers are using some common third-party framework, or using some older Apple and deprecated framework, or using some common component vendor, and that somehow got it wrong.

Nobody here knows. This could well be Apple. This could be something else.

The folks that have access to the failing gear for troubleshooting are the vehicle manufacturers.

Or to rephrase this, and here assuming this is an Apple issue (which is unclear), who do you want complaining about this issue to Apple?

You and a few others of us here in a forum?

Or, well, Honda?

Most modern cars, even cars dating back a few years, have the ability to take software updates. CarPlay didn't become ubiquitous until around 2018 or so. By then, infotainment systems were designed with updatability built in. You may not be able to do the update yourself, but usually, the car dealership has the ability to update an infotainment system. Newer cars now have Over the Air update options. And this doesn't just apply to Tesla.

if the infotainment system has CarPlay, it almost certainly has firmware. Whether it can be updated by the owner?

I updated the infotainment firmware in a decade-old pickup a while back, which cured various issues it had, and that infotainment system well predated CarPlay. It used a screwy setup and a USB stick, but it updated.

Check and update your infotainment firmware. Then un-pair, and re-pair, and try again.

2021 rav4… same issue..I have always use apple cords. I have taken it back to the dealer for a hard reset and even had the usb port replaced. I agree that the 16.5 IOS is the culprit and hope to have our issues resolved soon.

CarPlay disconnected in my BMW after I downloaded iOS 16.6. I am unable to re-connect CarPlay or Bluetooth on my iPhone 14 Pro Max.

Have you un-paired and re-paired? If not, start there.

After the update, my vehicle showed no phone connected and the phone will not connect via Bluetooth or CarPlay.

So, there was nothing to disconnect and reconnect.

Is the iPhone also showing as un-paired?

Settings > General > CarPlay

My BMW has no listing for my phone. It’s like there was never a phone paired with my vehicle.

So to confirm, you accessed Settings on the iPhone, General, and CarPlay, and there are no pairings listed there?

As stated earlier, This cannot be something the carmanufacturer(s) need to solve. This is an apple thing. How do I know? Well I bought a refurbished XR and this phone upgraded to IOS 16.6 Now suddenly my car (throught carplay) states that I need to Activate Siri ( which i do not want or need) and after that carplay worked normally again !!

I havent tried to update the iphone 8 to 16.6 to see if my hypothesis is true..

As long as I've used CarPlay, Siri has been required. CarPlay is a voice based interface to car infotainment systems and thus requires Siri as that is iPhone's link to voice activation. I think you are remembering something which isn't how it ever it worked.

No. It was not required in my 8 before I updated to 16.5.1. Never used Siri before…

You clearly were not using Siri, but it was available.

Siri is a fundamental part of CarPlay, and is also always part of Bluetooth connectivity, and very commonly has a driver-accessible control to summon Siri. Beyond the one button to summon Siri, the CarPlay interface is available entirely hands-free.

Yes, even on iPhone 8. My iPhone 6s was working fine with Siri and a Bluetooth infotainment system—not even CarPlay—in a ~decade-old truck.

For details of the particular infotainment system, check the owner’s manual. For many vehicles, there’s a voice command button on the steering wheel. This button for various Bluetooth infotainment systems, and for CarPlay support. (I suspect it’s even required for CarPlay support, but don’t have access to the CarPlay specs.)

Hi all, so I know this post has grown since my posting….

but to say after spending time on the phone to the Apple support team my car play is working again in my civic

we went through a series of resets…. And found that during one of the IOS updates a change to my network settings was causing my phone not to connect to the car for more than a second or two.

so reset of network and it’s back!!

I had the same issue with my iPhone 14 and 2020 Toyota Rav4. It worked fine before updating to IOS 16, but after, only maps would work when connected to CarPlay. I could see my song playing, but no sound. I tried the methods recommended by Apple several times with no luck.

What did work is resetting my infotainment system to factory default. I had to do a search on YouTube learn how to reset it, but it did the trick.

Hope it works for you!

Ok Toyota Hilux 2022 and I had the same issue with my phone and my wife’s phone.

After updating no more connection with Carplay.

So here is what I did to get it working again.

On the infotainment press Setup / General / Preferred Service

Here Toyota Online was selected.

So I changed it to Apple CarPlay and boom everything working again.

Hope this can be of any help here.
