In the RTA S65B(3d), it is specified that "sending or receiving audio or video files as a form of communitive function is an offence, and is liable on conviction to a fine not exceeding $1,000 or to imprisonment for a term not exceeding 6 months or to both".

Watching a video on your dashboard can be interpreted as receiving a video and you may be implicated on contravening the above section, whether the video is meant for the passenger or yourself.

Best to have a dedicated player for your passenger(s).
