Where can I get a VCDS cable compatible with my polo?

(I'm a real newbie, be gentle!)

I recently bought what I thought would be a good cable for recoding with my Polo, but apparently Polo isn't OBD compatible or something.
This is the one I bought: http://www.amazon.co.uk/OBD2-OBD-II-Cab ... =vag+cable

Can anyone point me in the direction of a compatible cable so I can enable a few VAG codes for my radio? Thanks!
