CarPlay - Increasing amount of “Connection Error” issues

Short Story:
I feel like I’ve been getting more and more frequent “Connection Error” issues with CarPlay. Anyone else having this experience? Trying to figure out if it’s the car or my phone (which is an iPhone 13 Pro running on the newest iOS, v15.5).


Long Story:
As a bit more background, I got the car ~2.5 months ago and pretty much immediately bought a Carlinkit 3.0 for wireless CarPlay. It seemed to work pretty flawlessly for a week, then occasional issues started (once every 30 or 40 trips). And now it seems like it’s having issues nearly every other day.

If I haven’t left in a haste and am already driving, I’ll turn the car off and back on and it seems to fix it. If I’m already driving, I’ll try doing wired CarPlay (which basically never works at that point). Sometimes it will boot, and Google Maps will run, but as soon as I try to play audio it will crash into a Connection Error.

I tried doing only wired CarPlay for a week and still had the Connection Error issue once or twice, so now I’m just really annoyed/confused.

Anyone happen to figure out what the culprit is here? Car? Phone? iOS bugs in v15.5?

Thanks!

Thanks! Yeah, it’s definitely not a cable issue.

I just did a more broad Google search and found some potential culprits. People were saying the Music app was causing it because of an EQ setting (which I didn’t have on, but I did have Dolby Atmos turned on) and the Overcast app (for podcasts) might be trying to download new episodes (which I read was the culprit for causing Spotify to crash CarPlay).

Hopefully turning those both off will fix it! I’ll test for a few days and report back.

I do the "wired" CarPlay, and I was having occasional Connection Error issues as well. I started tracking when these Connection Errors would take place, I realized every single instance occurred when I would immediately connect my phone to the car right after turning the ignition on, as the system was still booting up. I now wait a few moments longer after start-up and wait for the screen to say "connect compatible device." I have not had any Connections Errors since paying attention to my timing of connecting CarPlay. I'm wondering if because you were trying the wireless, that it would interfere with the boot up process and cause the connection errors?

I have NO CLUE if my theory holds any weight , or if I have just been lucky lol but i will continue to do what I am doing and hopefully no more errors!!

I actually thought I noticed this as well. The settings for the Carlinkit let you delay when it tries to connect, so I counted out how long it seems to take my car to boot up (~15 seconds) and set the Carlinkit to delay connection for 20 seconds. I feel like that helped fix most all of the connection issues (since before doing that, even switching to wired still wouldn’t connect at all once the initial wireless connection had failed).

So now I think I’m just struggling with what on my phone is causing CarPlay to crash after it connects (wired or wireless).

Can chime in, I’ve since reset my sensus to factory and as someone else said I now just wait for the system to fully turn on before connecting and it hasn’t had an issue since. Issue definitely has occurred when connecting the first second I get in or when the car hasn’t fully intilaized the CarPlay app/interface, it seems to get confused if the phone is plugged in as its first loading itself after a start.

That would be bad in my case, if one would have to wait for the carplay inface to boot up, before plugging in the iPhone.
I have an older iPhone in the center compartment, which is always plugged in. It's sole purpose is audio entertainment via Carplay.
What might have helped in my case was:
  • MY2022 car - replacing MY2021 car
  • removal of all podcast apps from the iPhone

With the "old" car I had the lost connection problem about once or twice a week. Now maybe once every 2 month.

I've not had any wired CarPlay connection issues yet in my two months old Volvo, but in wife's e-Golf approximately every fifth connection fails. Same phone, a flawless Apple original cable.

I tried to narrow the issue down and it seemed like the Google Podcast app was the culprit but I can't completely rule other options out. I switched to Apple Podcast app a week ago and haven't had any issues so far but it's way too early to make any conclusions yet.

Wow, I've had the exact same issue - but it's not limited to CarPlay. In my 2015 S60 I used iPod mode (over USB) and I had the same issue, in both my S60 and now in my V60 the fix has been to switch to Bluetooth, wait for music to start playing and then replug USB.

I am also a Overcast user so I wouldn't be surprised if that's it
 
#13 ·
In my last car (2014 S60) I abandoned the iPod mode because it kept trying to play my entire library alphabetically. Switched completely over to Bluetooth and basically never had that issue again!

Happened to me yesterday was weird my Apple Maps nav worked fine but if I tried to play music it wouldn’t start playing and would cause it all to lockup and then ” connection error”
Yeah, I was having that issue. Google Maps going fine, but then playing audio causes the “Connection Error”. Are you using either Overcast or Spotify? Also, apparently if you have an EQ on for the Music app (which you’ll find in the Setting app under Music) people were reporting that causing the Connection Error.

I’m still testing out using Wireless CarPlay again, but I had an issue today where it’s all going great (Google Maps and Overcast) and then suddenly the audio gets all choppy and touch inputs take ~5 seconds to respond. Switched to wired and got a “Connection Error”, but unplugging and replugging got it going (which was not the case for when it would crash when I connected too quickly after opening the driver’s door, it just wouldn’t ever connect until I restarted the car.)

Coincidentally, the freezing issue today happened in the exact same place that it happened a week ago (which is a place that I go through infrequently), so I’m wondering if there’s some strange signal interference being broadcast there? (Or if it was purely a timing thing that it happened to take me the same amount of time to get there?) I will drive through there again today and see if Wireless CarPlay bugs out again!

For me, the issue isn't plugging in too early, my culprit seems to have been having the standalone Spotify app installed in Sensus, and it somehow conflicting with CarPlay. I've since un-installed it from Sensus and haven't had any issues (fingers crossed). I'm also on the iOS 15 beta so its possible something was updated that helped as well
 
#19 ·
You mean iOS 16 beta? I’m really hoping it fixes some of the more annoying bugs!

And I’m pretty sure disabling cellular downloads for the Overcast app has fixed my freezing issues. I had an issue for the first time today in a week now where it wouldn’t play, and I just killed the app on my phone and reopened it and it worked fine. Didn’t freeze and then lock me out of CarPlay, so that’s awesome.

(Of course I’m still getting the occasional interference with Wireless CarPlay, but I’m not sure there’s anything more I can do there.)

I have had this happen multiple times and it was always Spotify that was crashing it. For some reason, certain songs, sometimes just crash Spotify and in turn, it takes CarPlay down with itself. I have a suspicion it happens usually when there is a brief interruption of service (internet) and Spotify just cant figure it out. When it does happen its absolutely infuriating because for the rest of the drive i simply cannot listen to music, doesnt matter if I turn off and on the car, restart my phone, reconnect my phone with another cable. It just refuses spotify for the rest of the day.

I’m sure there’s some way. I’m fairly certain Overcast (podcast app) was causing similar issues for me before I disabled cellular data. Killing the app and turning off my car seems to have always fixed it.

I think the most frustrating thing is the car computer only completely powers down if you turn off the car, lock the doors (including by just using the buttons on the fob while sitting in the driver’s seat), and then wait ~5 seconds. If you lock and unlock too quickly, the car computer won’t fully restart and the CarPlay “connection error” will persist.

Hi all! Reviving this thread to see if anyone has had any success fixing the issue where CarPlay will crash any time an audio app is started.

I can use Apple Maps just fine. But when I start Spotify, Apple Music, Apple Podcasts, NPR One, all start counting as if a track is playing. But no audio comes out and a few seconds later CarPlay crashes and the Connection Error comes up.

Any solutions? Thanks!

Yes! I thought I shared an update here. (At least I thought about doing so…)

What I’ve found will fix it is switching to a different audio input. Typically I’ll switch on the FM radio. Then, the next time CarPlay tries to play audio, it has always worked for me. (Seems to be a weird audio issue with the car?)

I’ve noticed this as well. Works fine until it tries to play audio and then drops connection.

Seems to happen intermittently. I’ll have to try the audio source trick. I thought it was a problem with my wireless CarPlay adapter and was blaming it.

I’ve had this problem for I don’t know how long. The two things that worked for me are 1) switch to Bluetooth and then it will eventually switch over to CarPlay or 2) I wait a few seconds after starting the car to connect my phone. So I’ll start the car, pull the car out of the garage, then connect. Not sure but I suspect it has something to do with the Sensus booting up and connecting the phone too quickly. I have had fewer issues going the second route. However, it doesn’t explain why I can reconnect with no issues if the car is turned off and back on while the phone is still plugged in (like at the gas station).

Hi
On my 2020 XC60 with Sensus I have to wait until both the Phone has connected to the vehicle message appears and the connect compatible phone message appears.
If I wait until both these messages appear on the screen I get 100% working connection to CarPlay.
If I don't wait I get intermittent sometimes working / sometimes not working connection.
Hope this helps.
Cheers Andy

Have this issue on and off.

The answer is pretty easy: Remove extra apps trying to play audio (audiobooks) and quit them. Then, ensure your Sensus shows Carplay under audio while it's connected. If you see both audio and phone set to Carplay on Sensus - you should be good to go. If not, quickly tap Sensus audio > "FM" > You should hear tunes right away. Now, in Carplay, play your audio again and it should work.

The issue is that Sensus is getting mixed input signals from the device (first bluetooth when car boots up, then Carplay when you connect iPhone, then iPhone is swapping apps within Carplay. Ive found this can cause a issue where Carplay and Sensus don't understand what's playing, which causes Carplay to crash if you play audio via Carplay (and note: you also won't be able to hear your carplay navigation). You may also see on your dash media view that your song is "paused" and isn't playing.

TLDR; click FM and then once you hear FM playing, try carplay audio again. You'll both get audio and it won't crash. You want to see "Carplay" listed under Sensus Audio and Phone.
