Connector for BMW Business CD head unit

**shimmy** · 26-04-2011, 03:35 PM

I have managed to remove Bealos Pioneer head unit easily and take off the facia and head unit sleeve and antenna, all good so far

But on disconnecting the Pioneer it seems to have an adaptor lead that goes from 2 bmw connector blocks (one orange one black) behind he unit to the Pioneer. Have disconnected this but the two blocks that are left don't match the BMW Business CD unit and are not really long enough........

QUESTION - Am I missing a BMw Business CD adaptor lead With connectors and if so where do I get it and what is it called?

Anybody got a picture?

Unless someone has been silly and chopped the original BMW wiring loom, instead of using a BMW - ISo converter, the BMW plug should be tucked up behind the dash some where.

Pull the red ISO plug in your picture out, it may require dropping the glovebox.

Spot on....found it, dropped glove box and found the original connector with still another connector attached and have removed and got the business unit working now,

Superb

4 Rainbow speakers and tweeters come out tomorrow if anybody wants a hot sound system (not 'hot' as in stolen)
