CarPlay disconnecting

Short update. After some discussion with the dealer and local distibutor, the issue seems to be an issue zpwith theinduction charger. It overheats the phone. Firstly it disconnects the charging function, then the phone goes in overheat modus and disconnects from the system. They have created a case on it and hope to get a solution soon.

My BMW dealer says that Apple continually releases s/w with bugs that they have to deal with. One thing he suggested to try is to hold down the power/volume knob and that will reboot your system in the car. That may help. I haven't had the problem since he told me to do that, so I can't say that I've tried it. My 530e did get better with the latest iOS and a BMW update.

That's just a flat out non-truth. Get rid of the bluetooth profile in the car, not the phone. People with Android Auto are having just as hard a time if not harder. So, I suppose all phone makers are against BMW? Coming from a company that charged subscriptions for CarPlay you think they would do better.

If you're having issues connecting with CarPlay, remove the Bluetooth connection between your iPhone and vehicle. Restart your iPhone and try to use CarPlay again. ... Go to Settings > General > CarPlay to see if you have any other CarPlay connections with another vehicle. Try deleting these to see if it fixes the problem.

So in plain speak, after you start car but before you set off, switch off blue tooth on iPhone then reboot your phone then put cable in if CarPlay connects to car display via cable?

in what order is this done I’m asking

No, just turn the bluetooth off before you get in the car. No Phone reboot.

Keep in mind: The cars systems will be active for about 20 minutes AFTER you stop driving and get out of the car. They do this so you don't have to cold boot it if you just do a quick stop.

Let us know how it goes.

The problem is the usb connection!!! When car play disconnects or doesn’t connect start manipulation of the usb end or phone end of connector. For me- this solves problem.

In case you didn’t see my earlier post about this, turn off Bluetooth and the USB should stop ‘disconnecting’.

I have a 2017 BMW M240i. CarPlay worked well with iOS 10 on my iPhone 7, but with the iPhone X and iOS 11 I’ve had the same problems with frequent disconnects.

I’ve noticed it happens far more frequently now that it’s summer. When it does, I get my wife to reboot the phone - she always tells me it’s nearly too hot to touch, and it almost unresponsive.

Seems to be even more frequent when I use the cars wireless charger, again making the phone hot.

Maybe CarPlay is just so intensive it’s overheating the phone?

Has anyone else noticed the same?

switching cables did not help me at all. I've had the most success waiting until after starting the car (2017 Honda ridgeline) iPhone 7 ios 12.1.3. Then if carplay disconnects, which it often does, I unplug from the USB side of the cable and then plug it in again.

While I agree but not fully agree, my point here is that I’ve had my new vehicle for almost a year and the manufacturer cannot figure out what is wrong, as others have stated they’ve gone as far as replacing the whole unit with no improvement. Others have resolved the issue by uninstalling certain apps on their phones. (Essentially not being allowed to use your device as advertised) ... CarPlay is Apple, the iPhone is Apple, without CarPlay, if my phone didn’t work in my car I wouldn’t expect my car manufacturer to fix the issue but instead my phone manufacturer. Apple has known about this issue since at least 2015 and it’s still not fixed ... the only things having issues are the Apple products ...

Same story as many of you, constant CarPlay disconnects. Set it to standard Bluetooth (BMW iDrive in the menu) and the connection stays solid.

Reached out to my BMW dealer and sure enough, others have reported the same thing.

Has Apple ever acknowledged that this is an actual issue? Seems this is far from an isolated problem given the significant number of forum threads that can be found out there about this......

I've been following this thread for awhile, and since my constantly disconnecting Car play Subaru is only 3 months old I took it to the dealer and asked them to fix it. They did a software update and I'll be ******, it seems to be fixed. Just FYI, maybe something that's worth a try.

I've reported my frequent disconnect issues previously on this thread. Last night, CarPlay disconnected during a phone call, and I just finished the call on the handset and hung up. Then my 2018 Audi Q5 MMI would not play any audio. Anytime I adjusted the volume, it popped up the graphic for adjusting the volume of the "phone call." In other words, the head unit continued to think a phone was attached to it and actively making a call, even though the phone was disconnected (no cord, no bluetooth), I had restarted the phone, and obviously CarPlay was not active on the MMI (head unit). I had to reattach my iPhone XS and make a call and then hang up to "reset" the MMI to release the phone call.

The reason I mention this is that events occurring with CarPlay during the disconnect persisted on the MMI, whether the iPhone was attached or not. Clearly, with all the reports of issues coming and going in association with iOS updates, the iPhone software is playing a role. But now I increasingly wonder if the CarPlay app (installed on Audi, BMW, Subaru, etc head units) has its own stability issues. As such, version "X" of CarPlay on vehicle "Y" may be a bad combination with an iPhone with iOS "Z."

Hopefully that made sense. And it may explain why some solutions work for some folks and not for others... because there's 2 versions of software and 2 kinds of hardware in play. As I've tried everything on my phone that others have suggested, I'll see if my dealer is willing to update the software.

Thanks all...

I have been a frequent complainer here because I have two recent model Subarus that have serious CarPlay stability problems - crash after crash after crash with 3 different iPhones. Based on that, it is easy to describe the problem as a "CarPlay" problem. However, over the past several months, I've driven several rental cars extensively that had CarPlay - that had no problems. Most recently, a Chrysler 300 and before that, a Jeep Sahara. Based on this experience, it becomes more difficult to isolate the crashes to "it's an Apple problem" since my iPhone works well with several different cars but not with my two Subarus.

I speculate the problem is an interoperability problem between certain versions of the navigation heads in various vehicles and CarPlay. I believe both of my Subaru models (2018 Outback, 2019 Impreza) have a Harman Kardon nav head. This same OEM nav head is used in a lot of other cars - likely the cars that many of you reading this have.

I am trying to find out who the OEM is for the Jeep and Chrysler - the cars that CarPlay worked fine in.

I did a hard re-boot ios 12.1.4, iPhone 7, Honda Ridgeline 2017 that had previously hundreds of disconnects; since the hard reboot of the phone I have had zero disconnects, going on 4 days now. fingers crossed....

Funny you mentioned it getting worse. Yesterday, CarPlay just dropped and I tried disconnecting-reconnecting ~10 times with no luck. Then I ran an errand for 30 mins, returned to the car, plugged it in and, voila, it worked. All previous instances of CarPlay dropping were resolved within a minute or so, though the number of disconnect-reconnect attempts varied between one to five.

I also experienced CarPlay dropping in the middle of a call. For ~10 seconds I could barely hear the caller on my phone (regular sound, not iPhone speaker mode) and the caller could hear me (unclear if via iPhone mic or receiver's external mic). Then my receiver magically switched to using Bluetooth and the call resumed to broadcasting on the car speakers and using the receiver's external mic.

All of my equipment (hardware) is new: receiver 2 wks, Apple cable 2 wks, iPhone X 1 month. This matters, IMO, because it likely eliminates poor physical connections as the root cause of the problem, by which I'm referring to worn USB port on receiver, worn Lightning-USB cable endpoints or dirty/worn Lightning cable port on iPhone.

Further isolating the problem to (possibly) iOS is that my receiver is a new model, but it uses the same "guts" as older models that have been around for several years. The primary difference between models is the built-in internal amp wattage. The receiver is running the latest firmware version.

To recap:

• CarPlay randomly drops
• "Fixing" it requires disconnecting-reconnecting Lightning cable, and even that sometimes doesn't work
• New iPhone X running iOS 13.1.3 (Lightning cable port isn't dirty or worn)
• New Apple Lightning-USB cable (endpoints aren't worn)
• New receiver (USB ports aren't worn, firmware up-to-date, system "guts" based on well-tested platform)
• The large number of complaints, coming from a wide variety of CarPlay-supported receivers, and frequent reports that CarPlay issues increased after iOS updates, strongly suggests the root cause is iOS stability/reliability.
