iPhone 13 keeps disconnecting from car bluetooth

My BMW is a 2012 - no CarPlay. Am I stuck with no bluetooth calling option? I'm amazed that Apple isn't trying to fix this issue.

Apple only notes yet more security fixes for 15.3.1.

What I don’t understand is that the iPhone XR worked perfectly and the iPhone 13 pro max doesn’t. What is missing in the 13 pro max?

My watch was/is up to date and I STILL have the car Bluetooth issues.

…and still not a word from Apple on this problem that seems to be pervasive.

How do you change the audio routing from automatic to Bluetooth headset as my 13 pro won’t connect or keeps disconnecting as well?

Also, would be interested to know what kind of case you are using on your iPhone. I just spoke with Apple Support and they suggested that my rugged case could potentially be causing the issue. I have an Otterbox Defender. What kind of case do you use?

Ok, for now - the reset all settings didn't fix it. It did give me options on other things that must not have been on my previous phone so at least it wasn't for nothing. Now, as for the 2nd part support wanted me to try was the Apple watch being turned off. I have recreated the problem twice with the watch on and I have a bluetooth connection issue to my airpods or car after around 6-10 minutes on a call. With the watch turned off, i've been unable to recreate the problem. I have no idea what the watch could have to do with it but might be some bluetooth interference coming from the watch. This didn't happen with my iphone xr

This new iOS, 15.2 update brought serious Bluetooth connectivity issues Mate, this not only happens in my car but even on AirPods Pro while I’m just listening to music. I can’t even make a call in my car. There’s serious issues with Bluetooth on My iPhone 13 Pro Max…Apple needs to fix this ASAP.

My solution was as follows: Shut Down iPhone 12 Pro MAX. Remove SIM. Put SIM into Pixel 3. Launch Pixel 3. Phone conects to bluetooth perfectly. I will use my old crusty google phone until apple decides to fix its OS. Honestly, this is shameful, Apple. I have even worked for you. Your quality standards have seriously dropped over time. It's sad that your ecosystem is not sharable with other phones. I use my iPhone for work, and it seriously hinders what I can do when it's failing to connect to peripherals that it once did in the last iOS. Please remember this Apple: Not everyone has the luxury of waiting for you to fix your problems, nor have we the patience to endure your "features." Sometimes our clients and bosses need solutions and we must deliver without an excuse of, "oH, srY my iPhOn3 is wOnKy Today." fugghedaboudit.

Yep. Now the connection works on my 2010 VW Touran. The 15.1 update did the job for me! Thanks 😀

I tried this with the dealer, we updated the firmware on entune, still drops calls. 2017 tundra.

on 15.2. Best of luck.

I just did update for my Prius 2016, let see if it change anything.

The exact same issue I’m having with my 2017 tundra. Exact!!!

No. Just iPhone 13. Nothing else

15.2 did not work. Problem still exists. Very disappointed in Apple’s failure to correct this major flaw.
