I have a 2016 Subaru with a 2022 Kenwood radio, and a 2021 Subaru with a factory radio.
Carplay works perfect in our 2021 Subaru.
In the 2016 with the Kenwood radio, it does not work with any of our iPhone 15 Pro's (4).
I have tried 2 different Anker A-C cables, an Apple MBP C-C cable w/adapter, the Belkin A-C cable that is certified for iPhone 15, AND the stupid C-Lightning adapter Apple sells.
Nothing works.
I believe its the phones, as the radio worked perfectly with my 12 Pro. Whereas with the 15's, when I plug in to the radio, Carplay starts up and will stay connected for 5 seconds then crash, but the phone continues charging.....
Very rarely will the connection stay up for 10+ minutes before crashing. I have tried 17.0.2, 17.0.3, 17.1 B1, B2....everything!
