I'm looking for the menu display where it shows all the devices connected to the system (I have a n3). Right now all I can find is a menu which will have three buttons displayed in the middle: Audio, Function (and whatever source I currently have playing) and Setup. I want the screen that shows all of them, how do I access it?

And am I actually making any sense?

If I understand you correctly, then you can just go to the source menu. It'll show what devices are currently hooked up by having some buttons available and others greyed out. It you can push the button, then the device is hooked up.

I believe you press the upper left corner, where it says "radio" or whatever. thatll bring you to the source menu.

Yeah I found it, thanks.
