2004 330Ci - CD Changer Comp?

Stupid question...but I am stumped...

I used to own a 2003 330Ci. I new the car was prewired for a CD changer so I bought an OEM unit (USE spec) from Chrutchfield. It came with the unit and adapter. It plugged in and worked flawlessly.

I now how a 2004 330Ci and wanted to reinstall this unit. WRONG! One of the connectors plugs into the adpter...the larger one does not.

Can anyone help me out? What is needed to add this CD changer back into my 2004. I would like to just buy an adapter...not a whole new unit.

What bus is a 2004 330Ci?? M ?? I ??? Just curious..

Many thanks

AFAIK the wiring hasn't changed for 2004. I think you have found the wrong set of wires. Look further on the left side.
