iPhone 15 CarPlay Not Working

every week or so, I post on this thread to remind people that are having difficulties using CarPlay with their new iPhone 15, you must completely reset your cars head unit for it to function properly. You have to find out how to clear out ALL phones that have been paired to your car, and make it as if your car just came off the showroom floor. Since I have done that, my iPhone 15 max connects to CarPlay faster than any iPhone I’ve ever had, it stays connected and all functions work perfectly. My iPhone 11 used to take 20 to 30 seconds to fully connect when I started my car. My iPhone 15 connects in about 10 seconds or less max. Most people that have success, have posted that they have completely cleared their cars head unit of all paired devices and then their iPhone 15 works perfectly.

I totally agree with your response regarding the car's programming. Restoring my 2018 Honda CRV to factory settings and resetting the Carplay settings on my iPhone brought back everything correctly and I haven't had an issue since then.

If I have to reset my head unit to factory that is a hack that’s not a fix. And then when I drive my wife’s car and plug in my iPhone 15 I have to reset it again. That makes no sense. I’ve never had to reset my head unit on any other iPhone.

Hi All,

I’ve followed the tips such as restoring my SYNC 3 back to factory settings, deleted all phones and reconnected just my own iPhone 15, toggled the airplane mode, purchased the adapter that Apple support suggested that I use, reinstated my $200 WiFi subscription for my truck ( just in case) updated to the latest SYNC3 by downloading the Ford update to a flash drive and successfully loaded to SYNC 3 system in my F150, and renamed my iPhone but my phone still keeps getting kicked off of my infotainment center. I tried my wife’s iPhone 14 and it works as it should..no glitches. I’ve reached the point of disappointment and have no more ideas. I’d really, really appreciate any feedback. Apple Support, although very pleasant to speak with, have not been very supportive in helping to resolve this issue. It breaks my heart to say but I’m seriously considering dropping Apple altogether and going to a Samsung should this not get resolved by this weekend. My 15 day satisfaction period is about to expire so I’m a bit desperate. Please help.

I have an update on my iphone 15 pro with the continuous disconnection issue. I deleted the google maps app, reinstalled it and everything now appears to be working as it should. The music plays from my phone, Google Maps is working and all at the same time. Hopefully this is the last of it.

That’s interesting. I was thinking that possibly an app installed on the phone might be the culprit. Maybe the folks that are unable to get it working using the steps outlined by myself and others in this thread have an app installed on their phone that’s contributing to the problem. My only other suggestion would be to make sure all of your apps are up-to-date and your iOS is up-to-date on your iPhone.

I was a bit surprised by this because my apps were supposedly UTD or at least I’ve got my device configured to update automatically at night. Apple support did do a check on my phone to confirm that I was on the latest update too, 17.1.1. It appears that the Google maps was what was causing all my problems. Very strange indeed but hey, I’m not complaining and I am just delighted that it’s working. My only hope now is that this experience can help someone else out there.

I just got a new iPhone 15 pro it won't connect to my car. i got the adaptor it works in my wife's car but not my car. I've tried anything nothing been helping its getting frustrating. any suggestions will help

My iPhone 15 pro max does not work with my Mercedes Benz GLB 250. I have tried several cords including the one that came with the box. It is an absolute inconvenience since I use CarPlay for directions. Apple needs to put out an update ASAP.

Allisacharles,

had the same problem with my iPhone and CarPlay. I ended up just deleting my Google maps app, reinstalled it and magically everything worked as it should. Maybe this will work for you too? Please let us know if it does.

I have the same issue. Tried multiple cables. Even when it does disconnect from car play the phone still shows as charging. Maybe it’s a software issue ? Either way I am very disappointed with the phone and just want to get my money back for this pos.

I am going to see how to return the iPhone 15 pro max to get my money back and switch back to my previous iPhone.

I would have thought your basic connections would have been tested. I guess not! I was hoping with the new update it would have fixed the issue. Again I guess not.

I’ll chime in once again.

I had the same problems with my 2019 BMW and an iPhone 15 Pro Max. It would connect and disconnect over and over. I deleted everything from my BMW. I deleted all of the phones cleared the entire head unit and made it as if it was coming off the showroom floor. I then made sure my iPhone 15 was updated to the latest iOS and I updated ALL of my apps. I was then able to get it to connect using the Anker USB-A to USB-C cable. It didn’t work the first time out of the gate, I had to delete the phone from the car and do the pairing process a couple of times, but after a few tries it began working. I’m just mentioning the brand of cable that I used, although other people have had success with other USB-A to USB-C cables. After using it via the cable for a few days I forgot to plug it in one day and it automatically connected via Bluetooth by itself.

All I can say is my iPhone 15 Pro Max connects way faster than my iPhone 11 Pro ever did, it stays connected and everything works perfectly.

Someone else mentioned that they had to delete and reinstall Google maps. I didn’t have to do that but it’s worth a try. If you read some of the older posts from people that have had success, it seems most folks had to clear their cars system thoroughly, sometimes multiple times before they had success.

I’m just mentioning that my iPhone 15 Pro Max works better than any iPhone I’ve paired with my car system. I see people saying they want to return their iPhone, so I figured I’d tell my story

Ok that’s awesome. A lot of work went into that and if you’ve got the iPhone Pro Max 15 then that phone must have cost about $3K. lol.

Simple truth to all of this is APPLE needs to put a few of their best code writers in a room for two weeks, feed them nothing but bags of chips (their choice of flavor) and cases of Monster or (from the old days) JOLT Cola and get this ridiculous problem Solved!!

My guess is when APPLE was forced to use a USB C input connector they forgot that USB C needs more POWER to run its peripheral gear than The old Lightning Connector.
