Does the Z120BT have a 3.5mm wired remote input? If so, has anyone tried using a Sony RM-X4S Rotary Commander / Remote with the Z120BT?

I've used the RM-X4S before with lower end Pioneer units (P8000BT, P7100BT) and all of the basic remote functions worked (track forward, back, fast forward, rewind, volume up/down, mute, source).

Yes, it works.

I know the wired remotes work via resistance, but does that mean many wired remotes will work with our units? All the sony ones should, but as far as I know there isnt any with a voice control button...maybe you could open up one of the remotes and change a resistor to map the feature to a specific button?
