Ford Focus Multistalk Adapter ?

I have a brand new MultiStalk Adapter and sony patch lead, I bought these from Halfords yesterday. MultiStalk Adapter cost me £29.99 Sony patch lead was £4.99 I threw away box and recipt, and bin men have been, halfords will not refund me or give me credit note. No longer needed, as i have gone back to factory stereo, i got sick of trying to get stereo fitted flush. If you have removed the standard stereo, and put your own in and still want to use the steering wheel radio controls, or the multistalk theb this is what you need. The multiadapter is for any Ford Focus, if you do not have a sony stereo, no problem, just go to halfords and buy a patch lead for make of stereo you do have only £4.99 each.
