Apple CarPlay Random Disconnecting

When you loose your wireless connection check your phone settings to see if you're still connected to the truck. I had some issues with the wireless connection dropping and realized i had several devices fighting for connection including my dashcam, once i disable the wireless auto connect for all other devices my connection has been more stable.

This has merit............. I recently installed a "Carplay" monitor on my ebike and facetimed my brother to let him see it in action........... While the iphone was blutoothing the ebike monitor, the iphone would not transmit my video signal to the face time call. Shut off the monitor and my video was restored.
 
Our 3hr trip to West Virginia was a success with Wireless CarPlay. I did have one instance that carplay was disabled; while picking my daughter up at school. To be fair, I may have shut the car off. We will be making some shorter trips over the weekend and will see if it crashes.
 
I think the upgrade finally has kicked it. Ive been in the truck for two days now, and have not had a disconnect.
 
Well the iphone update did not fix the issue, but it is happening less and when I reconnect it, the issue no longer repeats itself.

I’m back with you on that. It is noticeably better, but last night I had my first episode of having to manually connect my car to my phone
 
Me too having the same problem.
CarPlay is not working after iOS 18.4.1 update: I did a hard restart on the phone and manually made it forget the previous car connection - rehooked it up and I was finally able to get it working with its wired connection again."

I doubt the carplay connectivity issue is primarily an Apple problem. I don't have CarPlay connectivity issue with rental cars. Toyota is obviously not great at software.
 
The issue has been resolved as a result of the recent iOS upgrade on my iPhone to 18.4.1. The integration is quick with the exception of the SIRI callout, which mutes the driver's side speaker while leaving the co-driver unmuted. Consequently, if you have any music or radio playing, it will continue to play on the co-driver speakers, albeit at a slightly reduced volume, which is still aggravating. The background noise on SIRI Call it impossible to hear Siri's response. The LC's response is inaudible to you. My other models the speakers are instantly mute. Gotta live with it. The dickheads at Toyota Service don't seem to understand, Maybe Sammy fans not Apple.
 
At least for me the issue is not resolved. iPhone firmware 18.4.1 helped. I just installed 18.5 and hoping it fixes the problem.

Around town it gets frustrating with my apple music resetting randomly. Typically in the morning my daughter wants her "morning mix" (a heavily female rock / girl empowerment playlist). Around town I do not use the GPS that much.

In comparison on road trips we use the XM radio mostly and use the navigation and CarPlay seems to have less issues then.

I am just shocked how this does not impact my Wife's GM / parents Subaru / Mercedes rental with the same phone. And also how vastly different some of the functions are. I love in the GM when I press for Siri, the volume is muted (like everyone else except Toyota) but also the fan is stopped momentarily.

On the plus side, the Toyota app seems to be working better. I have even take a drive without my key without fear of having to walk home.
 
My CarPlay was working fine for the last few months, and now it just cut out after a mile of driving? The HU was fine, but it totally dumped the CarPlay connection, and it was turned off in the LC settings. Turned it back on, connected just fine. Weird..

We just got back from a trip and had a rental Mazda (new car). Had my iPhone plugged into the car and the CarPlay was arguably glitchier than on my LC, and this was a hardwire connection. Made me feel a little bit better about our LC issues.

Also learned a valuable apple maps lesson when doing a ~6 hour drive, and we choose the 'longer route' of three routes. We choose it knowing the 'shortest time' route would be a mess later with traffic. At some point during the drive, it switched to the shortest distance route without asking (or telling us). My wife thankfully noticed after about 20 minutes on the wrong route that it was taking us the wrong way. Sure enough, when we zoomed out... it had switched the route. We backtracked, but it added maybe an hour to the trip that was not awesome. Diving deeper into how to prevent that in the future, you have to 'add-a-stop' along somewhere on your chosen route to prevent from automatically going to the shortest time route. I seem to remember years past, it would ask if you wanted to change the route to save time? Not anymore!

To add to your sound advice............ I travel to Maryland several times a year and the map software refuses to route me through the country road bypasses around Richmond VA, etc.......... even with a waypoint, it still wanted to bring me in on a major highway and not where I wanted to exit the major freeways etc.......I ended up selecting a Wal mart in the little town at the exit I wanted (as I had tried every variant using the route function) And selecting that as my final destination, once I make the exit, I end the navigation and use the voice command to start the 2nd route to my in-laws house. This has been the only way for me to end up on the road that I want, which is the quickest way to the in-laws.
 
I guess this has been an ongoing issue with folks on the apple forums saying to 'provide Apple with feedback' about making a setting to keep the route you selected, and not change it.

It seems weird that the software developers can't imagine a scenario where we choose a route for a particular reason, and want to stay on said route... AI be damned. Maybe in iOS 36...
 
The Apple update didn't fix my frequent disconnects - it remains the same. It's not just my phone as my daughter's Apple phone also disconnects when she uses the Land Cruiser
 
I had many spontaneous disconnects on our month long trip that we just returned from. No rhyme or reason. Just Apple being a little bitchy..
 
I drove 4 hours round trip over the weekend and my phone disconnected 8 times randomly. I did have the hotspot configured on my phone and I to have a fixcam. I have removed the hotspot from my wifi setting, so I will have to see if that affects the connectivity. I has to be something fighting for the wifi. Its so frustrating!!
 
Wirelessly mine has always disconnected continually. I have had to use the data cable. I was just in Europe 4 weeks. My LC was in a garage and never started. When I got home, miraculously the wireless CarPlay has worked perfectly for 3 days. Fingers crossed. I have done two IOS 26 beta updates over the past 2 weeks ???

Had the exact opposite experience.. worked fine last few months, LC parked in garage for ~month and not started, now it has been disconnecting continuously. Guessing I should get on the beta update program, or else start plugging it in..
 
My disconnects were fixed by disabling auto join on the iphone to the vehicles wifi. I am still confused by how Toyota intends for wifi, bluetooth and cellular to interact with the phone. But I think the Toyota app was disconnecting bluetooth when it was trying to join via wifi.

I have no issues with using Carplay in non-Toyota rentals.
