Mine is really different from yours
I don't see the 'RAD2_bluetooth', 'bluetooth' nor the 'RAD2_usb' in your Man file...
I tried this morning to change settings manually, but it doesn't work either...
I'll post my MAN file tomorrow.
And another question like the one I asked to you on BMW-one, did you swap the wiring on the VW mic to make it compatible ? I have the VW mic too.
