So the CarPlay has been randomly disconnecting for a while now which started back around new years but has been getting really bad in the last few months. I went to the dealer for an oil change and mentioned this issue. I was not expecting much, and the dealer did not disappoint (even with video of the issue). They did however rebook the infotainment hoping that would fix it (it didn't).

My wife's Chevrolet has no issues with wireless CarPlay, and am amazed how many variations of CarPlay there are among brands. For example Subaru and Chevrolet mute the speakers when you summon Siri; not Toyota. I really like how Chevrolet even stops the HVAC fan from blowing during communications with Siri. Anyways I digress.

Realizing the dealer was going to provide zero help, I dug a bit further, and it seems IOS 18.X has been a bit flaky with Toyota. Looking into some of the settings on my phone I have made a few changes that appear to resolve the problem.

In the Settings => CarPlay => Toyota Land Cruiser there are a couple of changes I made that made things more stable.

1 - Disable Enhanced Integration. I really do not know what it does but I did not see any change.
2- Remove Home Screen Icons. I suspect some of the issue is potentially one of the apps; I do not know which; but I removed all the optional apps except my calendar. The apps removed included 3 X for EV charges (wife's Bolt) Sirius XM (not really needed with the head unit) Google Maps (I use Apple Maps for better or worse) and a few restaurants which I have never ordered from on the head unit.

A Couple hundred miles later it seems CarPlay works (again).

To be fair, I think part of the issue is the IOS 18 update. I am just shocked how every manufacturer has such different CarPlay without some standard functionality a lot of the issues. That said, My (previous) Honda and Subaru never had an issue and our Chevrolet is fine with IOS 18. That said, some of the changes I did reduced the issue from almost constant to a handful over the past couple weeks.
 
I also believe iOS 18 has created issues with CarPlay. Since I updated to 18 I have had a lot of issues where CarPlay is no longer shown and I have go through and start the whole install again and or go into the settings in the cruiser and tell it to enable CarPlay. I never told it to disable it.
ALSO my CarPlay does not work when I try to select it as CarPlay from the “sources” on the LC multimedia screen. I have pick the top option which as I recall just states Bluetooth. Then I have “enable “ CarPlay. If I select CarPlay from the sources options the next screen I see is asking me for a subscription. As I understand it CarPlay is not a premium paid for add on and should not need a subscription.
I am in the US.

This all could be true, mine has started disconnecting at least every other day. Sometimes the screen even goes completely black. And I know my iPhone just updated last week or so.

While iOS (may/is) partially responsible; the same iPhone has had no issues in my wife's Chevy Bolt (also wireless CarPlay); so there is some element of this which is Toyota based.

With some of the changes, I have had fewer issues, but I started to carry a USB C cord to see what happens next time it acts up. Not that it will really do much as Toyota Service is useless unless they have a TSB to work from.
 
Good point about using a USB cord, I did not think that would work as the car seems to want only bluetooth for Apple Play. Yesterday I had no issues, worked all day, but this was after I had to go through the steps I listed in my first post.
What I don't understand is why if I try to use the "Apple Play" selection in the multimedia selection screen, I get the screen telling me I need to subscribe. The only way I can get it to work is selecting the top selection which I believe is bluetooth, then find the screen within that selection that asks if I want to enable ApplePlay.

The CarPlay through the head unit when it is brought up to have a subscription is using the Toyota data plan. So if you were to run out without your phone ... ... ... Really, if you leave the house without your phone AND you have Toyota's data plan you can play your Apple Music.
 
I have also turned off enhanced CarPlay integration as I don’t think Toyota is using this feature.

AI overview:
Enhanced CarPlay integration, as demonstrated by Aston Martin and Porsche, aims to make the iPhone the primary control system for a vehicle's infotainment and digital gauges, offering a more personalized and seamless driving experience.
  • Full Infotainment Control:
    The next-generation CarPlay aims to replace the car's default infotainment system and digital gauges with the iPhone's interface.
From Apple Support:
With Enhanced Integration enabled, your iOS device will be able to work quickly with your car’s audio system to identify which installed apps are compatible with CarPlay, and how to best display those apps on your car’s screen. This is an optional feature that you can enable as CarPlay will work similarly with this feature disabled.
 
I turned off the enhanced, and still have to reconnect all the time. It was worth the shot though

I am still having issues; but they are less frequent. I have noticed that in my current setup when it acts up, after rebooting things seem to work. I "THINK" CarPlay has issues when some other app is open on my phone and it is contributing to the issue. It still should not occur. We just got back from Denver and had a Mercedes that had no issues and my wife's Chevy is flawless too.
 
I’d say it’s got to be the iOS-18, mines been squirrelly as hell ever since, I’ve even lost certain “buttons” in my apps. Like on Spotify, on the now playing screen it’s a crap shoot whether it will show the album art and the shuffle and like and whatever buttons aren’t there anymore, just boxes with question marks. And google maps can’t display any buttons either when navigating. Both apps will also not work unless I open the app on my phone first, and google maps will randomly just freeze and not show my movements on the map, which when driving the endless maze of highways in Houston is not ideal at all!
 
Downloaded this morning, everything worked fine droppping the kids off at school, but that’s about a 7 min drive. But so far so good!
