I am about to change my stereo and have read all of the thread and have a pretty good idea of what i'm doing. Problem is that I can't find anyone who can tell me the function of the Green wire with white stripe on the car end of the harness. Various diagrams either have it empty or state "unknown/unused" which isn't much help. One site referencing a later model suggested it might be linked to the vario roof being prevented from opening when the car is in motion. Since it plugs into the original Audio 10 then it must serve a function! Caqn anyone enlighten me?
