CarPlay disconnecting

Yesterday I went to the local Apple store. They erased and re-installed the IOS on my IPhone X. Since then, car play is working great. If it fails again, they say the issue will most likely be hardware at which time the phone will need to be replaced.

***Update***

I also have NordVPN on my phone. Last night I turned it off when running to the store and no disconnects. Today I left the VPN off all day and made 8 trips. No disconnects. So it looks like (for me) the disconnecting is related to my VPN. Im going to leave it off for a while and see if I get anymore. If it starts doin it again with the VPN off I'll update the post.

Success.... I removed the profile for the car in CarPlay settings, restarted my iPhone and plugged in using a genuine apple cable. CarPlay has been running for about an hour with no hiccups.

May also be worth mentioning, I previously thought that the CarPlay settings page was only for wireless CarPlay however, if you have made a wired connection to a car, a profile will be created in this page.

Been having exactly the same issue as everyone on this discussion, tried all the suggestion, but nothing worked UNTIL I turned off “Screen time” entirely. Ever since then, no problems regardless of cable manufacturer. My setup: 2018 Porsche 718 Cayman, iPhone 6, iOS. 12.1

It appears that in certain BMW cars where Carplay is wireless the connection is poor and carplay disconnects all the time. In some Evo ID5/ID6 units the WiFi antenna is missing. The Wifi antenna connects to the back of the unit which is very easy to take out (requires removal of 6 screws). It should be connected to the WLAN socket (the light blue connection on the right). Since I've connected it life is great and Carplay connection is excellent! WiFi antenna is cheap and can be easily ordered

I had a vpn on my phone that was causing the frequent disconnects - even when it was turned off. Deleted the vpn app and have had no problems.

I have a 2016 Honda Civic and after reading some other forums, I read a suggestion to delete the HondaLink app from my iPhone. After doing that, I have had zero disconnects. Out of curiosity, I reinstalled it a couple weeks later, and the disconnects returned immediately. So, for all of you driving cars from other manufacturers, do you have a manufacturer specific app also on your phone? It could be the conflict that's causing your disconnects.

*** UPDATE ***

As anticipated, the new iOS update 11.4.1 seem to have resolved the issues I experienced. CarPlay is working normal for me since the update. The response is fast and calls are not dropped or jumping between the phone and the vehicle.

I did not go to Apple to wipe and reinstall the iOS as it is not needed.

CarPlay is not dead to me anymore.. its alive! 😉

I like a lot of others have been troubled by this issue. The problem seems to be caused when your phone auto locks and I found solution by going to settings/Touch id & passcode. Scroll down to allow access when locked and turn the USB devices option to ON. This solved the issue on both my mine and my wife’s phone in both our cars

Had CarPlay on for 2 hours this morning, no issues (Screen Time off). As a test, disconnected it from the car, turned Screen Time back on, rebooted the phone and turned the car back on, CarPlay connected ok, but disconnected itself after about 5 minutes.

Again, turned off Screen Time, rebooted the phone, connected everything back and no issues after 90 minutes.

Definitely looks like something related to Screen Time, or perhaps even some of the background services supporting Screen Time for my particular “environment”. - iOS, IPhone and car.

I wanted to be sure I have a fix before I posted this. I have been following this thread very closely and have had multiple trips to the Audi dealer for my 2018 Q7 experiencing the same problems with my iPhone XS. After months of issues and trying everything posted here, I made some changes two weeks ago and haven't had any issues.

1. Turned off screen time tracking per another post (did not fix issue)
2. Deleted old MMI profiles from previous Audis (this did not fix the issue but I'm putting everything I did)
3. Turned off Activity Tracker for phone and all app under "Health"
4. Made sure Settings - Privacy -Location Services for all apps were either "Never" or "only when using"
5. Turned off Settings - Privacy -Location Services -System services for Location Based Alerts, location based apple adds, location based suggestions, all "product improvement"

I really think it's the activity tracker because if I left Pokemon Go on running in the background I would always have issues and there is a new feature for egg hatching on that app which used Activity tracking. I noticed my phone would have issues if it moved in a certain way or if I was going between service areas. It may have been the combination of 3&4. I haven't had any issues in two weeks where before I disconnected several times per day.

I posed this ...

I think I found the problem with the disconnect in CarPlay.

I have a KIA 2018 Stinger GT2. I have Had this problem for 4 months.

Are you ready .... Apple (iPhone) MAPS has been causing the issue.

I stumbled across it when I turned off the Radio and closed the apps on my iPhone.

Apple Maps popped up on my Radio. (Not the Nav that comes with the Radio) It was running. I didn't open it or use it! it must have been running in the back round using resources. I deleted the App from my iPhone. Thank god (Apple), lol allowed users to uninstall there apps.

Once I did that I rebooted the iPhone connected back using the same Lightning Cable and proceeded to see if every thing was still functioning, it was, then I took a drive. Everything is working perfectly. Even all the information for Waze, SiriusXM and other music providers are working great.

Been working with no issues for about 10 days straight. WOW, what a relief.

Funny thing though, every once and a while a little window comes up and reads "Apple maps needs to be installed. go to the apps store". LOL.

I have the same problem using iPhone X's and BMW 330e. After digging into it it seems that the car's WiFi is the culprit. What seems to to the trick is when reconnecting you should disable and enable Vehicle WiFi (uncheck and check) at the idrive menu at manage mobile devices -> settings. Then quickly to to your iPhone, disable WiFi and turn it on again. You'll see BMWxxxCarplay. Connect to it and then go to idrive in your car choose manage mobile devices check your iPhone and select apple car play. This will last for your journey. The problem with me that I have to repeat this almost every trip. I guess it's either a software defect of the head unit or a faulty WiFi antenna. Theater could be replaced. You can Google it.

ok - spent some time on a chat with apple support before resorting to har reboot. I ahd already done all the steps of software update, different cable, etc and isolated the problem to my phone. Solution was to rename the phone and to forget the car. when i reconnected with the cable to the car, the phone resynced to the car with the new name. drove around for several minutes past the time when the phone would usually disconnect. this time there was no issue and no disconnect. will monitor this. but this may just have done the job. very happy.

Wanted to chime in on this one as another forum member has...

At least for me, iOS 12.2 has appeared to resolve my CarPlay disconnection issues. I updated the day it came out and immediately began testing.. so far have seen zero disconnects.

For those still with disconnection issues, give 12.2 a try, given it's free and all.....
