steering wheel control for radio not working

Hi ive just changed the steering wheel in my 2003 e46 today fron the 4 spoke one to the msport multifunction wheel.

But the radio controls are not working just wondering what do I need to get this to work ???

Any help be much appreciated

was the 4 spoke wheel you had in before the new a mfsw is well did it have buttons that worked ?

if not you need a loom to wire in the buttons , you can buy the retrofit loom from the dealers

its around 25 euro heres a good guide on what to do http://forum.e46fanatics.com/showthread.php?t=544160
