I have e39 2002 530d Touring with standard wiring loom for radio .Currently have a Business Tape Radio 40 pin flat connector.
I thought I'd be clever and upgrade to a Business CD unit but now cannot get it working..
I can connect the 40pin connector to the CD top unit, but the lower mid requires a 10 pin connector I do not have...
with wires I dont have..:-
White with Black stripe and yellow rings
Red with Black stripe
Violet with red stripe
violet with brown stripe
brown with black stripe.
Can I wire these in from somewhere? do I need a CD wiring Loom (please dont say that..it'll cost more than the cd...)
Any help wopuld be appreciated..
