CarPlay keeps failing

[mattski2112]

Counterpoint: in 6000 miles and 2.5 months of ownership, I’ve not had one instance of unintended disconnection. Pretty pleased with how my iPhone works with the head unit.

What model of phone and OS version are you running?

Apparently iOS 18.4.1 resolves this issue.

Does anyone else have the issue where once a month the radio just randomly disconnects your phone from Carplay. I have to go back into the settings and turn carplay back on manually. No rhyme or reason to when it happens. Is there a software update for the truck.

Update your phone to 18.4.1. Specifically this update fixes some CarPlay connection issues. If havent already.

Yeah mine was very flakey before.
much better after that update.

no glitch’s for 5 days now.

Some of of my glitches are predictable and readily duplicatable. Hasn’t changed with the update to 18.4.1. Maybe moving to an iPhone 17 in Q4 will help.

Just completed about 1,200 miles of travel over the last week, flipping over 10k during my many travels. Was running software 18.4.1 on a NEW phone and STILL had persistent CarPlay dropping issues. Happened both wirelessly and while plugged into the head unit. It‘s the only thing I don’t like about the truck. As an aside, with all the highway travel, my overall MPG is creeping up and is now at 19.5 since purchase about 11k miles and 5 months ago.

Like @mikeymtbs I never have any problems with CarPlay. I am running 18.4.1 on an iPhone 15 and it never disconnects. It is really strange that for some of us it is perfect and for others it is flaky as hell.

I reported 3 posts ago that mine improved with the update. That was short-lived.

Now its flaky again. At least give me a button on the main screen that reconnects it so i dont have to dive 4 menus levels down.

You can restart CarPlay with a voice command - quick and easy and no menus to navigate. If your phone is disconnected you can also reconnect it with a voice command.

Thanks. I'll try it.

Thanks. I'll try it.

My truck seldom loses CarPlay anymore but relaunching it with the voice command "Hey Toyota - launch Apple CarPlay" always works for me. On a few occasions the reply was iPhone is not connected, and the command "Hey Toyota - connect iPhone" has always restored it. I see people shutting off their trucks, navigating the obscure menus or rebooting the whole interface, and there is no real need for that pain.

I have a Sport Upgrade with 14 inch monitor that was purchased in October 2024. I experienced Carplay drops like described here while using an iPhone 14 Pro, but only at times and it was not a terrible issue. Quickly fixed by resetting the radio by holding in the volume button. This did improve and no recent drops. More annoying was that music would not mute when a text came through and music played via Apple Music or Spotify was not the same quality or could reach the same volume as the radio. I recently got an iPhone 16 Pro with the latest firmware and found that CarPlay connects much quicker, no drops, music quality over CarPlay has improved, and music mutes properly when texts are read. Also the Siri signal has changed appearance from some sort of flashing glob to a flashing frame around the screen. Seems that bugs for the most part have been fixed.

I finally figured out my issue with CarPlay. I finally realized while driving it was disconnecting in the same areas in town, and I got to thinking that it had to be wifi related. In fact, my phone was dropping the CarPlay wifi for XFINITY WIFI. The below changes had completely solved my issues.

On your iPhone -> Settings ->Wifi ->Edit (top right) ->scroll all the way to the bottom to "Managed Networks" usually, AT&T, Comcast, XFINITY WIFI, etc, and TURN OFF auto-join.

OMG this is amazing!!! My CarPlay has been working great, except that about a mile from my house if I cut through a nearby warehouse area. At the same place CarPlay disconnects if I stop at the light, and will pause/skip if I catch the green light. Drives me crazy because I have been in the truck for a few minutes and usually just settling into some music or a podcast at this time. I was actually going to post about this today and saw your post. I just jumped in the truck and tried your fix, problem solved!

Who would have thunk! The old "auto-join" gremlin. Wait. Wasn't that a car a long time ago?
