Opel Corsa E and Canbox GMF6

[FunnyBug]

@Ivo
You said the steering wheel buttons Vol+ and Vol- are swapped. What about the other buttons (Call/Speak, Hangup/Mute, Src+, Src-, Src (push)) ?
There shouldn't be many further buttons in the Corsa E. Lighting, seat heating and maybe climate controls (if you don't have the simple/manual A/C).
What about door opening detection, parking distance detection and warning signals (key, light, etc.).
Do they all work as expected ?

The issue of the volume up and down buttons on the control panel being reversed can be resolved by reversing the volume up and down button settings on the main unit.

HIWOORD SONG, that's the simplest fix IMO, mate. Ivo, dont bother wiht the steering wheel learning app becuase it only reads analogue buttons, so look in teh car or CAN settings for a volume swap or reverse option instead. Had summat similar wiht an aftermarket stereo years back and it was just one tick box buried in a menu...
