[QUOTE=Arty;11382922]It's a 17 pin setup. The 40 pin came in with the post 2001 cars with Business CD or professional 16:9 Nav, So I have the 10 pin supplementary connectors.
all business cd players, and the professional cd player use the 17 pin connector.. at least every single one that i have seen does. the 2005 business cd player in my car does aswell
there seems to be some misleading info about this... a lot of aftermarket accessory manufacturers state that its all 40 pin after 2002 or something... that simply isnt the case... as least not with the business cd player anyway.
