Hi, and thanks to all who’ve posted on here. I’m just discovering how the audio ( yes, and video) work on my recently purchased 2006 Alphard. I’ll likely be back with some questions once I’ve had a look around and discovered what is obvious. It was a couple of weeks until I managed to open the head unit for access to CD player (with another port for an SD card like on my old camera). I’ll now have a scout round for RCA connections.
I, too, have drop down screen in rear and remote control. Nothing happens yet ( but remote turns it on). Will fiddle for a while and…..likely be back to pick your brains!
