The set is good for the price. The bracket must be pushed almost to the 1st bend, then press both clips outward and pull out. The intermediate adapter I have not needed my Opel radio CDR 2005 and the new JVC radio are polarized correctly. The radio panel is simply clicked into the double-DIN opening and holds up well. Previously, of course remove the radio and the black mounting frame. Then insert the mounting sleeve from the new radio, bend a few noses, connect the radio, check radio reception, and push up the rear. DONE. The adapter fits all Corsa model years 2000-2004. Could be something precisely fitting, the area above the radio is a bit thin. Also, the surface is smoother than the dashboard. But these are only small things. This set really would have the antenna adapter to be there.
