I finally decided to try and connect my iPhone to the PCM via the y split cable using a 30 pin female to lightning Apple certified adapter.
1) PCM recognizes the phone when I switch to iPod source.
2) PCM display is not active but iPhone Audio plays thru SUV
speakers.
3) iPhone controls are active BUT
4) the volume controls on the PCM, the steering wheel and the iPhone Do Not work but the mute function does work !
This is pretty weird to me.
Maybe I’m missing something or a setting on phone perhaps??
Any thoughts on this is appreciated !

Decided to connect an older iPhone 6 and the volume controls on PCM and steering work ! Reconnected newer 13 mini and it also worked. Shut down vehicle, restarted and 13 mini no volume control again. Grrr. Reconnected the 6 again and it worked and then mini worked. I think lightning cable has to connected in alignment so signal path is a straight shot . I also think PCM 3.0 is somewhat flakey. I don’t think Bluetooth 30 pin converter route will be much better based on what I’ve read. I’ll keep playing with it.
