I am considering replacing the original Philips radio in my E30. Part number PC2-05-04 from
http://www.bluespot.co.uk/install/show_model.asp?id=23 will convert the original wiring to ISO but what is the small 10 pin plug for? What functionality will I lose without it? Sorry about the crappy picture, they still haven't designed a digital camera for idiots.
