Had a play and made up a cable etc. Hacked the code up a bit just to display the output of the steering wheel controls to the serial port debugger.
Works well reading
Still cant get it to output anything to the Cluster DIC yet though
EDIT: I can get it to display but it seems to only change if im scrolling the wheel while the head unit is sending packets (like moving the radio volume knob and the scroll wheel on the steering wheel at the same time
EDIT2: If i plug it into an old VE with no Infotainment it shows up on the cluster when i move the wheel... intersting. Suppose I could put my old cluster in and test it.
