today i finally recieved my stero adapter from kufatec so i can replace my single dinn with double dinn stero. just fitted adapter to new stero and nothing happen's, it's as if there's no power . when looking at the power plug on the audi loom there is 4 wires going in to the car plug, thick brown, thick red and blue wire, thin green with blue stripe and a thin brown ( possibly with a white line ). on the new adapter only 3 wires are used, the one not being used being used being the thin brown wire with ( white stripe ). i managed to eject a cd that was left in it but get nothing else. any help would be greatly recieved, as it's just been one thing going wrong after another lol.
