Hi Ive just bought a pioneer p70bt hu for my 07 gp active all is fitted fine except the steering wheel controls which dont function! I need help, I've asked Halfords and they are beyond useless! :bang:

Go and buy the adapter. £50.

Autoleads PC99-X89 and patch lead for the pioneer will be needed.

this will only work if your new headunit has steering wheel compatability.

im gessing the blue and me wouldnt work even with this adaptor?

Nope.
