The installation instructions say:
However, the RNS-E does have a TV tuner input. So it MAY be possible to connect the RGB outputs of this unit into there. But I cannot find any mention of audio ... this unit appears to NOT provide an audio path - which kind of limits it's applications (maybe that's why they talk mostly about backup cameras?)
Since the RNS-E is an "all-in-one" unit there is NO externally accessible RGB signals for this unit to connect to in the manner they describe.
