For an original Blaupunkt car radio on a vintage Fiat Grande Punto 2008, keyed does not position the plugs on good limestone plateaus of the car radio. We must carefully remove the sheets of plastic end, finding the right plateaux on the unit, and resize the alignment key in order to connect the plugs on the necessary limestone plateaus. Once completed craft, it works correctly, the sound is pretty good. For the price, it is not very serious, but a neutral card without keying might do just as well.
