So I want to hook an audio source (my iphone) through the AV input......I'm looking at the back of the unit and see there are RCA inputs.....so I connect through my iphone's headphone jack (with a headphone to RCA adapter) and I can't seem to get it to work. I go to the AV source screen and it won't let me select AV input as an option. Do I have to turn it on somehow? Any help would be appericated.
Thank you
