Nissan LEAF Wired Carplay -Carlinkit 5 Wireless Dongle iPhone Video interference

I successfully used carlinkit 5 to allow Wireless CarPlay from Leaf Head Unit -which nativley uses Wired CarPlay.

Basically I paired iPhone to Dongle which works very well apart from odd lag.

What I need to know is which of these devices are Stopping or Blanking iPhone 14 Camera when used in 4k/hd Video recording mode.

Is it cause I use AirPods Pro as my Voice Audio Source whilst iPhone records short Video.

Maybe it's Carlinkit which pairs to Leaf EV CarPlay via usb initially then Bluetooth.

Is it AirPods Pro conflicting with Carlinkit/Leaf CarPlay connections.

Why would bluetooth clashes stop iPhone video recording.
