iPhone 12 Pro and Bluetooth Connectivity.

This morning, 09/21/21, I downloaded the new iOS 15 push. Lo and behold, my iPhone 12mini now works perfectly in my 2009 Chevrolet Silverado pick up. This, after countless hours on the phone with Apple tech support, two letters to Tim Cook asking, no...begging for help, several conversations with Apple administrative staff, with the final recommendation from the genius Apple engineering staff to visit my Chevrolet dealer for a firmware update...as if, somehow, Chevrolet should be responsible for Apple's software/firmware compatibility with older generation vehicles. At one point they (Apple support) were suggesting that I purchase a new truck! Unbelievable. I'm beginning to think that maybe Apple is not a happy home. I use to be a total Apple fanboy, but now...I'm not so sure.

I’ve been having the same issue on my 2009 GMC Sierra: Bluetooth on iPhone 13 (acquired Nov 2021) and/or its software has been failing to connect or disconnecting almost every attempt.. It had worked flawlessly with SE and prior iPhones since the truck was new. I have tried every possible fix I could find suggested on this and other discussions and per call with apple tech support which was well handled by the technician who acknowledged apple engineering is recording the cases and working on the problem but had no determination as to it being hardware or software. One settings combination that has better success is to have speaker routing in accessibility>touch>call routing set to Speaker and in the device type of the paired vehicle to also be set on speaker. Unfortunately this will route all calls even when not connected to your vehicle to come through on the speaker and your voice to text will also be unavailable whenever you are connected to your vehicle. And it does not guarantee that it will automatically send a call to your vehicle forcing you to toggle the speaker button to Bluetooth which essentially notifies hands-free operation. Further at the end of the call, if it connects, the Bluetooth will disconnect so then you have to wait for it to reconnect in order to make a call. I have verified this is consistent when pairing A different iPhone 13. I await an iPhone SE 2020.

Updating existing GM radio software does not work. Only option is to replace with aftermarket radio with bluetooth phone capabilities. Expensive conversion if you want to retain Onstar and steering wheel controls.

I have the same problem with my 2009 Silverado. After the iOS 14.3 update I could receive calls on my Bluetooth but I cannot make calls. It keeps connecting and disconnecting. Prior to this iOS update it would not work at all.

The phone works fine in my wife’s vehicle.

Another annoying thing is when it connects to bluetooth it turns the volume down. So, when I’m disconnected if I forgot to turn the volume back up I’ll miss calls and texts. It’s very irritating because this phone is used for business.

Just called my Gm dealer in Peterborough On. He explained to me that it’s due to the Bluetooth version difference. He suggested connecting the iPhone to the USB port using the cable. This will keep the Bluetooth connection open.

while its not cordless, it’s better than having dropped calls. Why couldn’t apple tell me that ??

Try deleting the entire contents of your iPhone, then set your iPhone up as a new phone. Before adding any third-party apps or files, i.e. MP3 files, photos, etc., pair your phone to your vehicle and see if it works. My experience has been that in this configuration, the phone should work fine, without MP3 files in particular. Good luck. Don’t forget to back up your phone first, just in case.

Apple has no intention of fixing this. Been back and forth with the engineering department on this and they keep telling me my truck isn’t compatible with their phone. They got a tick ***** when I told them that it was their phone that was made incompatible with our vehicles. Every other iPhone I’ve had has worked fine until we got our 12’s last year. After going back and forth with them they said they’d send me some AirPods so I could call while driving. I told them these are more of a distraction than using my phone on speaker. I guess that’s the end of it. Quite possibly my last iPhone I’ll buy. They used to care about the customer but not so much anymore. Thanks Apple.

I accidentally called my son from my truck the other day and it worked fine. Tried again this morning as well as 2 other people. Seams to work fine now.

I recently updated to IOS 15.3.1. I assume that was the fix.

I too participated in the upload, but had not heard anything since.

I thought I posted this earlier today. I have an iPhone 12 just updated to IOS 15.3.1 Appears to have fixed my issue.

I agree that I believe it to be a hardware issue more than software. The recent iOS update, iOS 14.4, did seem help, but did NOT rectify the issue 100%. It now will generally work with phone calls, but as soon as you elect text to speech in iMessage OR Siri, same issues persist - connect, disconnect, connect disconnect.....

I believe that there is a hardware issue and Apple is trying to resolve it through software instead of replacing everyone's iPhone 12 mini (or iPhone 12 with bluetooth issues). If you search the internet you will see articles regarding a delay of deployment for the iPhone 12 due to the bluetooth chipset.

This is not the way of Steve Jobs - "it just has to work." Apple, go back to your grassroots - and remember the user experience and "it just has to work" mentality prior to shipping out hardware/software. I'm begging you, PLEASE don't turn into the Microsoft model.

We just upgraded from iPhone 6S to 12 Pro. My 2016 Kia has no issues with pairing the new phone and calls are clear with no issues. Our 2010 Chevy Silverado, however is a nightmare with call dropping issues. The phone pairs, sort of, but contacts and Siri won’t work. Calls are dropped/cut out after a word or two. We’ve paired/unpaired, turned off/on, multiple times. Judging from the responses here, it may be a firmware problem with the GM electronics. I’m reporting the issue to our Chevy dealer and Apple. Hoping for a solution soon!
