I have a CD30 and the lack of MP3 and bluetooth really bugs me so I'm thinking of getting this and would like your thoughts http://www.halfords.com/webapp/wcs/s...Id_265857#tab1 , it says I will need additional wiring so the steering wheel controls work, would I be right in thinking it would be this... http://www.halfords.com/webapp/wcs/s...egoryId_265880 , I presume I will need some kind of surround to go round the unit, that I cannot find... any Ideas?

Cheers
