Hi
I have had a DSE for 3 days so far but i think it goes something like this:
Top Row: Low Range, Cruise Control, up-down rocker for suspension, back fog, front fog (if present).
Steering wheel the bottom two buttons when orientated normally, are the set for cruise control and reset for cruise control.
the top buttons on the wheel correspond to play/pause, ffwd, rwind, skip etc.
Not sure which as I don't have those on mine.
