Hi everyone - my first post from sunny Brisbane, Australia. I have recently imported a 2021 Hybrid Alphard SRC with JBL headunit. Slowly working my way through figuring out how everything works! I have seen that some Alphards can use IR headphones in the rear seats and I was hoping someone may know if this is possible with my car please? The remote control for the rear screen does not have any buttons that are audio source or headphones etc and I cannot seem to find anything in the menus so I am reaching the conclusion that it may not be possible but thought I would check if anyone knows for sure. Thanks everyone.
