Have the bought the Pioneer for my Opel Corsa C, quite honestly if I had known all this before, I would have left it. With the radio alone is not enough, a new Radioblende you need in addition because the supplied does not fit due to the fact that you have to reduce the delivered radio holder, it is too large or you can buy a universal. Furthermore you need a Adabter antennas and a new plug-in connection to the radio anzuschliessen.Das Pioneer fits in Corsa C it's just a matter of money. A power cord must be placed on continuous current ignition is unsuitable because the lighting is not off. The Pioneer itself is great, it looks great and it has enough power, the sound quality is great ... about the Pioneer myself, I can not say anything negative, it is a good device. Who needs to be decided by the Pioneer for the Corsa C to pick up approximately 220 Euro expect anything Accessory cable connection, antenna adapters, radio holder and radio bezel. I hope that I could help.
