CarPlay problems after iOS 10 Update

My experience has completely deteriorated suddenly to basically "unreliable". Yesterday, I received the "no device" box literally 10 seconds after music started playing. I had just started my car, everything synced up and I barely even made it out of my driveway.

Today, first experience was the head unit display going totally black for CarPlay. Everything (including my phone) indicated everything was still connected and playing music. After switching the head unit display to something else and then coming back to CarPlay music, it displayed and I could pause/play music but no sound. I had to unplug/replug my phone in before it would work again.

I took the time to backup, wipe and restore my phone. Wiped all settings between the head unit/phone. First ride, "no device" 10 seconds after music started playing.

Although I've tried switching cables, I'm going to try an Apple cable now. There's a post elsewhere that some are convinced that the root cause is using non-Apple USB/Lightning cable. I'm skeptical as I do not buy cheap knock off cables (those can be dangerous), but at this point I want to completely rule everything out that I can.

It isn't the cable (or should not be.). I have tried a bazillion Apple and 3rd party cables and they have made no difference.

I am 24 hours into an experiment of having "iCloud Music Library" disabled on my iPhone 6+ and have not had a single CarPlay mishap. Not happy I had to do this but I am going to run with it for a bit and see how using Apple Music without it pans out. Also playing around with Spotify and Amazon Music to see if either might be a "crutch" to use until all this CarPlay mess is worked out.

I’m having an issue with Apple Music and CarPlay in my 2016 Honda Civic. Over a period of several months. I have been troubleshooting this issue in respect to different apple devices, cables, car settings, and the potential of other factors causing the issue. I have been able to identify the steps needed to reproduce the issue. The issue is not limited to a specific Apple device, and affects other car infotainment systems with CarPlay.

The issue is this, I can connect my iPhone to my vehicle and the CarPlay interface will come up fine. After approximately 2 min the screen will say device not connected. Sometimes it will continue to play music but the only way to get CarPlay to come back up and work properly is to unplug the phone and plug it back in.

My research and troubleshooting has led me to discover that the issue is in some way related to having a large music library and having iCloud music library turned on. It is as if the cars system is trying to build an index of all the song titles in the library and around the two min mark it hits some sort of limit and crashes the entire system. I have tried to resolve this issue through several means with no success other than simply turning off the iCloud music library. I would really like to be able to have access to my music library and use CarPlay but am unable to do so until this issue is resolved.

As I have been able to reproduce the issue with other vehicles and CarPlay systems I’m not sure if the issue is more of an Apple issue or a car system issue. I am inclined to believe that Apple could resolve the issue as there was a previous version of iOS where my vehicle did not have this problem.

​

However the problem seems to be related to a memory issue in the car infotainment system itself. It could easily be resolved with a setting where you could turn off indexing of the music library. I had a similar issue in an older Ford vehicle and this was the solution. I tried to do this by turning off the song by voice setting thinking that setting is what causes the system to try and index my music library, but that didn't resolve the problem.

Chevrolet's service contacted me today.

They said that the main problem is the onstar technology. It's causing some kind of conflit with carplay and android auto in theirs newest versions.

A firmware update will be released in may. I really hope so.

Since my last response I've had almost zero problems after having switched to a brand new Apple lightning cable. (My prior cable was brand new but not made by Apple.) The only weirdness I've seen is when I was using Apple Maps (not the built-in to the head unit) and stopped for gas. When I restarted my trip the head unit display only showed a black screen - hitting the head unit's "home" button then going back into CarPlay fixed that. I've seen that happen a few times since when just playing music but the fix is the same. Yesterday I experienced the "No device connected", unplugged/plugged my phone back in and it happened again a minute later but hasn't since. I'm interested in seeing if I can go for another few weeks without any issues before it happens again.

I recently purchased a 2017 Hyundai Santa Fe, and I was having the same problem with Siri not reading my text from the notifications. Recently, by accident, I noticed that if I set the ringer switch to silent, Siri will read my messages without issue. I would like to have an audible notification, but at least I can get my messages! Hope this helps

I have a 2017 Hyundai Elantra and also recently noticed that if my phones mute switch is on it will read back messages correctly every time. Soon as I turn it off it doesn't work again.

Also have an issue where maps doesn't always open in night mode when it should.

Seen plenty of people say these things started with iOS 10 (I didn't have CarPlay before iOS 10 myself).

I sent feedback to Apple about it and encourage everyone else do the same.

I was able to get CarPlay to connect consistently with my iPhone 6+ running 10.3.1 and my 2017 Honda CR-V Touring by deleting both profiles from the CarPlay section on iOS and then re-adding the phone via USB *only*. Here's what I did:

* in General --> Settings --> CarPlay, I deleted both profiles (there was one for wired USB and one for wireless

* in Honda --> Smartphone --> Apple (CarPlay), I deleted the entry for my phone

* turned car off completely and then started again

* wait for Honda system to turn on fully (i.e. wait until home screen appears)

* connect iPhone via Apple USB-Lightning cable

* in Honda --> Smartphone --> Apple (CarPlay), I re-added my phone

* in General --> Settings --> CarPlay, confirm only one profile with option 'Allow CarPlay while locked'

The key was to only have that one profile in iOS CarPlay with that option (which indicates it's the profile for wired USB.) If you see another profile with the option to use CarPlay when phone is near car, that's the option for wireless (I deleted this profile... not clear that my car supports wireless CarPlay.)

Another indicator: if phone is unlocked, the menubar will turn blue if using wired USB connection for CarPlay, purple if using wireless CarPlay (or what it thinks is wireless CarPlay.)

Hope this can help some.

I've finally had my 2017 Civic in for its first service, provided them with the long list of things I've done on my end and a request to either a) upgrade the head unit software or b) perform a factory reset. They said I'm already running the latest version, and I *think* they did a factory reset but since they didn't explicitly say they did so (my wife picked up the car) I did it myself. A week+ later of stability, I saw the dreaded "No device connected" screen.

The *only* "advice" Honda provided was from a tech note that claimed after a "phone upgrade" (no definition if that's in reference to phone os or physical phone) to "...perform a factory wipe". My experience - it doesn't solve the problem. I have an iPhone 7+ and have zero issues with it - rock solid at all times, even when physically connected to a computer for a full wipe/restore like I've tried before.

It's been a few weeks since I last posted. Since then (05/08) I've had 12 instances of the CarPlay connection suddenly dropping, to include the head unit acting strange while music was playing. Some of these, including 2 that occurred within 10 minutes of each other after forcing a complete reboot of the head unit, occurred **after** I did a "factory reset" of the head unit after my phone was updated to iOS 10.3.2.

I'm now tracking all of this in a spreadsheet to include the date/time, what happened, what I did (typically forced a reboot of the head unit because I'm in the middle of going someplace). Quite frankly this is thoroughly ruining the enjoyment of my new Civic. I was so excited jumping from my no-bluetooth, old Civic to this one so I'd have this capability and not have to deal with a bluetooth headset or fumbling with both a power and audio cable all the time.

Based on the sometimes funky behavior of the head unit, and when this occurs my phone still has the CarPlay graphic showing onscreen for a bit after the head unit displays the dreaded "No device connected" and the phone still indicating it's charging, I'm pretty convinced the problem is with the head unit/software and not my phone. I've had zero issues with my phone for any other purpose, I've tried different cables (including an Apple) and the behavior is always the same.

The problem doesn't just occur with the music app running. For the last few days I've been listening to a podcast using the podcast app. Since I just started it there were ~44 episodes to listen to - not a very many when compared to the contents of my music collection (which is still very small compared to what others have posted).

The dreaded "No device connected" appeared. Turned the car off, drove it later and on the return home it did it again. Rebooting the head unit it "jammed" on displaying the basic main screen (no buttons, just the background visible) with audio playing. The center display below the speedometer showed "No device connected" and no button on the head unit worked - you touch them and they'd simply beep.

Happened to stop by the local Apple Store due to our daughter having an issue with her phone. While I was there I talked to someone - he wasn't aware of any major issues and offered two suggestions: a) use Apple's phone support where they can provide troubleshooting assistance while I'm actually in the car b) wipe the phone, but don't do a restore from backup (or use a different phone).

I'm a bit hesitant to just wipe my phone and not do a restore (other than tie it back into iCloud for stuff there), so I'm going to try dropping the amount of music on the phone to < 9000 songs to see if that fixes it.

Reducing the number of songs on my phone didn't resolve anything, it stayed the same. This past weekend the head unit *completely* locked up and black screened. Even turning the car off, letting it sit, turning it back on wouldn't bring it back to life. Drove it over to the dealership where the tech there saw it and could confirm there's some issue. I have an appointment for later today where they're going to take a look at it. They've never seen one do what mine has done this time and suspect it'll have to be replaced. After leaving the dealership it finally started working again - but <24 hours later it did it again ("No device connected"). Usually it takes 2-3 days and hours of driving - this was the next day and less than 20 minutes of driving. I'll update as things progress....

Apparently they were able to recreate the problem at the dealership. I provided them with my log of failures/getting it working plus everything I've tried plus screen shots of the various weird states it would get into. They called the Honda hotline and will be replacing the head unit in my car, it'll be a few days until the part is in after which I can get it scheduled and hopefully have resolution to my particular situation. I'll update after the replacement and a bit of time has past to see if it resolves it.

The head unit was replaced on Tuesday, the car really wasn't used Wednesday. Today driving home from work the "No Device Connected" message came up again. I'm now going to completely wipe my phone and *not* do a restore to see if there's some corruption in something on my phone. Short of this, it's a software problem either with CarPlay or the head unit.
