Does anybody know where the wiring from the steering wheel audio control goes?
Does it go straight to the radio or is there an interface in line somewhere?
I have had a look at the module on the steering wheel and it appears as though it just varies the resistance depending on which button is pressed.

I actually want to hook it up to a MFD sat nav (made by Blaupunkt and badged VW/SEAT/FORD), I am also trying to find out what protocol that uses.

i'd look for a converter box
i know there out there for cd player but ive normally used them for sony or pioneer cd players but i'll see if they make one for blapunkt

I don't think it uses a Blaupunkt standard.
I'm guessing that the system is based on the I2C bus with the Clock and Data terminals on the back of the unit.

I think the only way I will find out for definate is by putting a scope on one in a VW or Ford.
