I Have Just Removed My Blauepunkt Head Unit On A 55 Plate Active Sport And Wired My New Sony Head Unit In. Their Is A Problem Tho. There Is Power To The Sont Unit Cuz It Takes The Cd But The Front Panel Doesnt Light Up And Work Like Their Is Not Any Power To It ???????
It Is Not The Head Unit Because Its Happend With Others I Have Tried.

On my Bravo i had to swap the Red and yellow wires round in the adapter which plugs in on my Alpine i had a similar problem (if they are the same!)
