I own a 54 plate (2005) combo van and originally had a CDr2005 CD/radio. I decided to upgrade to CD30 MP3 which was taken from an Astra H, 56 plate (2007 I think), but when I received the MP3 player, I realised the connectors on the back weren't the same. I thought I'd just be able to plug in and go, apart from the swapping round of a few cables here and there. They are totally different locks altogether. Can anyone advise me of a name or model number of an ISO or similiar, that I can use to go from my vans original quadlock male to the CD30 MP3 female and and where to find one please? Any help would be much appreciated.

Thanks, Paul

PS, I know I'm going to lose my display in the van, but that isn't important to me.
