Hello, I have fitted to my 2004 vectra a cdr 2005 which is on its way out on the cd player and volume control, I have a nearly new cdr 500 which I removed from my 1996 omega b, can it be fitted to my vectra and are the block connections the same? Has anyone done this conversion? Obviously I will need a double din to single din dashboard adapter but these are available. Regards Richard.
