iPhone 12 Pro and Bluetooth Connectivity.

Exactly the same. I end up turning Bluetooth off. Strangely sometimes it will work perfect and then the next call it won’t. I don’t understand why Apple can’t fix this. It’s not like there are updates fir our vehicles that we get where gm could fix it and it’s clearly an Apple problem in the new phones.

I have the same problem with a 2009 Silverado. It will not allow me to make calls. It says "Unable to make call with bluetooth device." or something like that. I have unpaired it. Deleted all the connections. Nothing works. I'm going to be forced to return the phone if they can't get this fixed.

That doesn’t work deleting all your files my phone was brand new out of the box and it wouldn’t connect to the blue tooth in Gm Truck 2009 Chevrolet Avalanche… so Apple needs to fix the issue tooo many people are complain about it

I’m currently having the same issue with my 2009 Cadillac Escalade. iPhone 8 worked perfectly with it but not with the 12 Max. Connected my wife’s IPhone 12 Max to it as well - same results. Apple totally failed on this issue. Total headache. I would have kept my IPhone 8 for this calling feature alone. Dissatisfied Customer!!!

Walk me through the steps you took. I have done everything from hard reset, forget GM, remove all contacts, removed phone from GM, reset networks. Nothing has worked. Can receive some calls but cannot call out. Message (cannot call from your bluetooth device.)

So, after loading iOS 15 and reporting that my iPhone 12 mini worked perfectly, two days later and we are back to the same old thing...on-off-on-off-on-mostly off. I am done. The new iPhone is a complete POS. And for Apple management, read Tim Cook, FUAY.

Well as reported by other people after downloading IOS 15 Blue tooth worked and two days later the same issue raises its ugly head and the same problem all over again starts…. Apple needs to fix the issue 🤬

Facts: In 2009, GM sold 6.5 million vehicles in the USA. In 2010, GM sold 8.39 million vehicles in the USA. That's a total of 14.89 million vehicles. Today, the average person owns their vehicle for 12.1 years (2009-2010 vehicles are still in that age range). 80% of ALL cars built in the last 20 years are still on the road. 47% of all smart phone users in the USA own Apple iPhones. Most iPhone users upgrade their phones every 2 years. 51% of iPhone owners upgrade their phones as soon as their cell phone plan allows an upgrade.

Conclusion: This is HUGE! Potentially, millions of iPhone 12 owners or soon to be iPhone 12 owners are, or will be, affected by this issue. I wonder what it will take to get Apple's attention on this issue?

Has anyone tried updating GM radio & updating IPhone 12? I am about at the end of my 50/50 warrantee from the used car lot. Owner said he would pay half the cost to have GM update radio. Is it worth it???

PS I have back up camera, not even sure I can replace radio with out loosing back up camera.

I’m curious if the iPhone 13 will work? If Apple fixed the issue with the 13 then it could be a good argument to repair/replace our phones. If anyone on here gets a 13 chime in and let us know if it works.

I have a 2009 Chevy Tahoe and I’m having major Bluetooth connectivity problems with my new iPhone 13. Apple could not help me when I called today. My phone has the latest software version ,15.1, and I’ve done everything that was recommended. Now I wish I kept my iPhone 8 Plus!

I just tried mine again (2009 Chevy Silverado) and it still didn't work. If I place the call via bluetooth, it connects for about 2-3 seconds then the call drops and continues to try to reconnect back and forth. I then have to pull over and turn the vehicle off and call just using the phone. Sometimes incoming calls work. I do have the update 15.1.1.

As mentioned before, this can be a safety issue that Apple needs to fix.

Sucks that Apple doesn’t does NOT see this as an issue or problem they need to deal with. I’m still traveling but don’t have much hope that IOS 15.1.1 has solved the issue with my 2009 Avalanche. Thanks for the info.

To everyone who has been posting similar problems. I have to give Apple some credit. They contacted me today and set up a phone call to try to diagnose the problems we are all having with the IPhone 12s. (again, I have the 12 and have a 2009 Chevy Silverado).

The technician (Rich) took the time trying several calls to me to replicate the situation and was able to have the same problems. We spent over half an hour trying several things and creating a log showing what was taking place. With 3 incoming calls one came through without a problem, but the next two only lasted a couple of seconds before failing. My outgoing calls still have the same issues with dropping off after initially connecting via Bluetooth.

He is passing along the info and data that he gathered and downloaded from my phone to a higher level of support to look at. Hopefully they will be able to figure out what is causing the problem.

I should have mentioned that Rich (the Apple technician) was genuinely concerned, worked with me in an understandable way and explained things (to a non-tech person) which was appreciated. Much better than dealing with someone that is hard to understand half way across the world.
