Been following this thread for a while now. Initially found this forum after noticing that my 2012 Infinity QX56 and my launch date, iPhone 15 Pro Max was just unusable. Over these many months, I've been able to test this on the following Year/Make/Model vehicle's:
2012 Infinity QX56
2019 Honda Pilot Touring
2015 Honda Accord EX-L
2024 Kia Seltos EX
2018 Honda Civic Touring
From my small sample size of automobiles, this would appear to be related to the year of manufacture?
The only 2 I have problems with, are the 2012 Infinity and the 2015 Accord. Both exhibit Bluetooth connection and playback issues. No problems with later models.
I am and Electrical Engineer and RF is my specialty, but have zero (okay, not zero) knowledge of Bluetooth. That's about to change. There is a reason for what we're all experiencing and I'm going to find it.
Probably going to get pretty technical, so I'll start a new thread. I'll post a link, when I do.
