CarPlay not working after iOS 18.3.2 update

my fix - it works again in the meantime - worked the following:

on iphone: delete/forget the car in BLUETOOTH. Next: delete Wlan (car) in WLAN settings. Do a Power/rest (the one with the tricky loud/silent followed by right button) stuff

oon/in car: delete iphone. optionally do a reset of the processor unit of the car (in a BMW it works with pressing the power/mute button for 30sec). At the end scan for new mobile and connect the phone again via carplay …

for me it still works

Here’s a couple of steps that worked for me when CarPlay stopped connecting after an iOS update:

Restart both your iPhone and Car: Sometimes, a simple reboot of both devices can fix any temporary connection issues.

Forget and Reconnect the Car’s Bluetooth: Go to Settings > Bluetooth on your iPhone, tap the “i” next to your car’s name, and select “Forget This Device.” Then, reconnect it by pairing the devices again.

Check CarPlay Settings: Make sure that CarPlay is enabled on your iPhone. Go to Settings > General > CarPlayand see if your car is listed. If it is, tap on it and select “Forget This Car,” then try reconnecting again.

Check for Updates: Sometimes, an iOS update can cause temporary bugs, but Apple usually rolls out fixes quickly. Make sure you're on the latest version of iOS by going to Settings > General > Software Update.

Reset Network Settings: If all else fails, you can try resetting your network settings. Go to Settings > General > Reset and choose Reset Network Settings. Keep in mind this will reset Wi-Fi passwords, Bluetooth connections, and VPN settings, so you'll need to reconfigure them.

Check your Car's System: Make sure your car’s software is up to date as well. Some cars need firmware updates to fully support the latest iOS versions.

If you’ve tried all of this and it still isn’t working, it might be worth reaching out to Apple Support or your car’s dealership to see if they have any additional suggestions or if there’s an issue with the update itself.

Indeed, it works again! Thanks mschl :-).

iPhone:

• delete Bluetooth entry
• delete WiFi entry
• restart iPhone

BMW:

• delete iPhone entry
• reset CPU of the car (30sec hold power/mute)

Connect everything again ...

Same here... I have iphone mini 12 with ios 8.3.2 and I drive a BYD Dolphin. Previously (7 months of ownership), I have never encountered any issue with the apple carplay. But since 8.3.2, I have encountered connection issues twice. Tried forgetting device and re-pairing without any success. The only that works in both situations I encountered were : restarting both my iphone and resetting my infotainment system.

Have you tried deleting your Bluetooth connection and recreate the connection?

After deleting connections on my iPhone with my vehicle and the connection in the vehicle and setting things back up again, then it all worked as it should. I’m just bothered that this was necessary at all.

I don't know whether this will help; right now all is working fine with the latest iPhone upgrade which for me is 18.3.2. When I did have the issue, I had to reset the system on my Honda CRV, and after that it set up fine. I figured it out myself after Honda nor Apple could help.

Upgrading to 18.4 fixed the wireless CarPlay but corded still does not work.

A guy at the dealership has a 12 on 18.3.2 and his corded worked.

idk if anyone running iOS 3 or 4 versions old to be able to ask if reverting the iOS would work and that can be a pain.

Exact same thing here. My 16 Pro has iOS 18.3.2 and connects through Bluetooth (media+tel), but can't connect with CarPlay. My wife has the exact same 16 Pro, but still with iOS 18.3.1 and her phone connects without any issues.

We're not connecting with a cable, all wireless. Brand new BMW X1 with latest iDrive version.

My iPhone 13 was working fine tell the up date 18.3. My iPhone 11 and my daughter iPhone 14 worked just fine. I also took my phone to Best Buy and I also brought my 2023 car back to the dealership to make sure it wasn’t my navigation. I was ready to just get a new phone. I did one more thing I got a cord on Amazon that said CarPlay cord and I made sure it said compatible with my (iPhone 13) it must say CarPlay

I was experiencing the loss of corded CarPlay with my 16 pro max and running 18.3.2 but it was intermittent then stopped all together. I tried to buy a wireless CarPlay adapter off amazon and same thing worked for awhile solid, sporadic then completely nothing. So I said f it I went years without it and use Bluetooth to do everything. My phone connects thru Bluetooth to my car but sometimes it will say it’s connected and play but nothing comes over the speakers. This I found I needed to forget the device on my phone and car and reconnect everything was the fix (tried various combos of forgetting, disabling and power cycling).

A friend’s 14 was acting the same as mine, cables would charge and CarPlay worked intermittently on my car for corded CarPlay and the wireless adapter.

Well today $115 later the dealership told me nothing was wrong and one of their techs had a 12 on 18.3.2 that works but the 14,15 and 16 that were tried were not functional running that. They would not connect to the wireless adapter because it was after market :-/ but after the update and 2 days at the dealership I was able to connect to wireless CarPlay. If it wouldn’t have worked I was about to go to Apple and have them revert my phone back three iOS versions so I could have CarPlay back. So fing frustrating!

I may of figured out the cord. It has to say it works with CarPlay when you order the cord not just lightning cord cause that doesn’t work CarPlay cord that works with your specific iPhone. My phone is now working in my car

This should be fixed in the next release as some of us were able to confirm the fix in a pre-release version that we had installed recently.

My personal cell is an 14 pro, was 18.3.2 and CarPlay didn’t work. Upgraded to 18.4 and CarPlay still does not work. My Work phone is a 13 and on 18.3.2 connects and Apple CarPlay works. Still haven’t figured out what the problem is.

I updated to 18.4.1 this morning. Still the same issue :-(.

I removed BT entry on my iPhone and also the connection entry in my BMW iDrive. I even did a Network Settings restore on my iPhone (as suggested here also ...).

This is really getting annoying and ridiculous. So very disappointed now in the Apple ecosystem...
