CarPlay Disconnecting - iPhone XS Max

Dear all wise and all knowing Apple Community 🙂


I recently switched from my iPhone 7+ running iOS 12.0 to an iPhone XS Max running iOS 12.0.

I have a 2018 Audi S4 with the latest firmware from Audi.


With the switch to the XS Max, seems that my Apple CarPlay will get into a cycle of disconnecting and reconnecting

every 30 seconds or so.


I tried reverting back to my 7+ and works fine.


1. Siri is enabled.

2. The USB Lockout is turned off on the XS Max. The 7+ had the lockout turned on

but made no difference in the XS Max toggling on or off.

3. Swapped the cables to the one in the box of the iPhone XS Max and USB ports

in the car. This had no impact on the XS Max recycling the connection. The 7+ is uneffected

business as usual.


Not sure if this is tied in with the authentication issue with the charger. I go over wired carplay and the 30

second increment is suspect as that is my lockout time on the phone.


Curious if others are facing this.


Thanks!

I thought my issues had been corrected by the 12.1.3 update and my XS Max was running carplay fine even on non Apple cables (however they are MFi certified).

Went on a long drive yesterday and it reset a couple of times.

However, I think reset is a mis-characterization of the issue.

It is related to notifications from Apple Maps.

I correlated the screen dropouts to the exact timing I received a "You are 14 mins from home" type notification from Apple Maps.

Therefore I may disable notifications from Apple Maps to see if that fixes the final issue.

However, this morning I see there is an available update to 12.1.4 so not sure what that now fixes.

An interesting chain of events happened after I updated from 12.1.3 to 12.1.4.

My CarPlay connected in my KIA 2018 Stinger then disconnected then Connected then Disconnected and then Locked.

Had to reboot Iphone. My CarPlay connected then disconnected then stayed connected.

Before the update my Carplay was running perfect after 12.1.3.

What the **** happened iPhone support. Did you just decide to push the update from pressure or lack of ambition.

I guess the one thing that came out of it was SiriusXM did finally fully load the GUI on the CarPlay.

I'm not the only one getting frustrated.

Car Manufactures and Dealers are tired of hearing about problems as well.

I don't totally blame Apply Support. I also Blame the Car and Truck Manufacturers.

I had a n Android Phone one a long tme ago. They have unproved Tremendously. I do not want them to take over the Market place. I work at Lockheed Martin as a IT Sr. systems analyst and Integration specialist's Manager. I was involved in the migration to iPhone from Blackberry and Android.

Please this right.

Thank You.

Finally, after about two days in my Audi workshop the problem with CarPlay constant disconnecting in my A4 Allroad is solved, hopefully...At least it worked constantly all the drive home flawlessly👍.


According to workshop, it was a bad connection between the MMI actuator and stereo module causing the USB ports to switch on and off. It was not related to iOS, iPhone, or type of cables.


Thans for all your support with my troubleshooting!

Hi All, The issue I've discovered on Bentley is this. Bluetooth when its on is what the car looks for so if you have a wired phone to USB and unless you have ticked the box which says don't ask again, the car will always be looking for a bluetooth connection. The answer is to try ticking the dont ask again box which tells the car to stop looking for a bluetooth connection. If that fails to resolve the issue, try disconnecting the car in the iphone under bluetooth and it should now only work if wired in. Doing a reset can also resolve the issue but not always. So I connect with a cable, disconnect all available bluetooth options and tick dont ask again.

After spending 60 minutes troubleshooting with Apple Customer Service, I seemed to have solved the problem after suffering it for 4 months. The solution is as follows, and so far the problem hasn't come back (fingers crossed):

1- Delete or forget all phone devices from your car

2- Go to settings and delete or forget all cars from your phone Bluetooth and CarPlay connections

3- Go to settings, general, about,name and rename your phone. Just change whatever name you phone have on this field.

4- Re-pair your car and phone again

5- Enjoy, and hopefully it works for you as well it does for me.

6- You're welcome!
