The silver facia adapter is a perfect fit for my 2005 corsa C, matching the colour perfectly, and the removal tools work very well too.
However my happiness was soon swung to disappointment as I removed the previous adapter from the standard stereo. It was a completely different connection, which I later found out to be a quad connection. Apparently all vauxhalls post 2004/5 when the vauxhall D shape came out, also had new connections. Why change something that is easy to use and works? I do not know. I am not 100% on every vauxhall > 04 having this type of connection however so I would check first. It is worth noting that my corsa has the steering wheel controls also, and centre dash display. All of which was within this quad connector.
