Sounds kind of weird setup you have there.

Lets clarify some terminology though.

The large ring that you turn for skip forward/back, is spring loaded or should be, if you "twist" it forward, then release it quickly, it goes 1 track forward, if you twist and hold it, it will skip forward until you release it.

Like Volume does - i.e. if you twist and hold the volume knob it ramps up or down the volume, twist it then release it move the volume up or down by one "click" like the knob does on the front panel.

The other knobs change their function dependiing on whether you configued the stalk on the left or right hand side of the steering wheel [see the stalk option in Emplode for this].

The one that is closest to the dashboard i.e. either the rounded button or the "sunken in button" turns the Empeg off if you press and hold it, if you touch it briefly it pauses playback.

The others: 1 brings up the Menu, one acts like the Cancel buttons does and the other one works like shuffle on/off.

The "button" on the end of the stalk should change source from Player to Aux then to AM Tuner [if fitted], then FM tuner.

Shift track Forward/Back will select next/previous visual [even when visuals are not on screen].
