[inscrutable]

Got the new iphone 15 with os 17.0.2 installed.

It pairs fine with my 2015 bmw. But when making calls, the bluetooth connection to the car either drops immediately, or a few minutes into the call.

Spotify (and presumably other audio) works fine.

This has never been a problem with my iphone 13 pro.

I've tried unpairing, deleting the connection on both sides, as well as a "fourth reset" where you hold the volume button down for 30 seconds to force a reset. Nothing has fixed the problem.

I checked on the website, and it says there are no new software updates to the bluetooth.

Does anyone else have this issue? Is this one that a software update will fix? Or was there something wrong with my phone (hardware) or the way I transferred my old phone info to my new?

HELP! This is driving me bananananas....
