Apple CarPlay keeps disconnecting (2021)

Wireless CarPlay on my 2021 Hyundai i30 keeps disconnecting at random intervals. In addition to that, it also disconnects at one specific location during my morning commute to work without fail every morning. To me they seem like two different issues, even though they share the same outcome.

The audio unit issuer for Hyundai, Seednav, has already released an update regarding this concern and I have installed it in my car. Unfortunately the issue still remains the same. Recent communications with Seednav have resulted in the blame being pointed towards apple. Is there a fix in the making for this issue?

The latest update from Apple (14.5) has given me enough proof to say that this is mostly an Apple issue rather than the manufacturers. Ever since my phone was updated to 14.5, the dropouts have reduced significantly. I managed to do a 3 hour journey today with maps and spotify running for the entire jorney without any issues.

Although it hasn't completely cured the problem, it seems like we are one step closer to the solution.

Did you ever find a solution for this problem? I had a 2020 Hyundai Sonata, and Apple Car Play (not wireless) worked like a charm. Then someone t-boned me, and I got a 2021 Hyundai Sonata with wireless Apple Car Play, and it keeps disconnecting. I deliver food for GrubHub, so it's a major problem for me. When i went to the dealership to ask what could be done, they didn't seem to know and claimed that there have been lots of issues with the wireless Car Play. Yesterday, I got a message on my dashboard that said, "Apple Car Play brain damage!" What the ****?


If you know anything I don't, please pass it along. Thanks!

2020 Kia Sportage, this started a few months ago for me.

I thought it was the phone case not allowing the plug to stay.

Switched cases and same thing.

I rely on Waze and Siriusxm for my commuting.

I find this now to be dangerous as I have to either plug and unplug over and over or...it does it alone sometimes but never stay on.

Enough finger pointing, GET THIS FIXED NOW.

I just did the latest ios update and didn't resolve this issue.

I agree, but I have read nearly all of these posts here and elsewhere and the cars include Peugeot, Honda and others.

My beef is my car was fine for two years and what changed ? Apple ios did.

I'm calling my dealership now and it was just in for a recall for something else. If they had a fix for this they should have done it then.


I'm not here to pick fights, I am looking for a solution.

Because the phone staff at any large company does not know about every bulletin issued on every problem, they just know what their database tells them and what they are updated upon in meetings.


Quite frankly, many people have gotten in arguments with their dealerships, who have insisted there are no updates available, until they show their dealer the image above, at which time their dealer looks it up and says "Wow, our system didn't show anything."

I had a 2020 Hyundai Sonata and never had a problem with Apple Car Play disconnecting. Then someone t-boned me, and it was less expensive to get a 2021 Sonata than a used 2020 model. I drive for GrubHub, and it's critical that Apple Car Play work so I can get directions without pushing buttons. But with the constant disconnects, I have to push the button to reconnect at least every 5-10 minutes, and sometimes I have to reinstall Apple Car Play altogether. This feels like (another) accident waiting to happen!

Okay, so I drove 8 hours to southern PA. Thursday and used my iPhone, didn't work plugged in at all. I just turned off the Kia AV unit.

Tried it again the next day for 4 hours and nothing.


Yesterday (Monday) driving back I used the wifes Samsung phone with carplay and it worked flawlessly the whole way back.

7 hours straight and no disconnects.

Those are my results, make of it what you want.

All I know is my Carplay is dead till my phone works with it.
