Well, my Ford Fiesta had 2 connectors, one with speakers, the other with power... I got a Ford to ISO adaptor without any trouble.

I think the Din and a Half stereos had the same plugs on (Last time I looked was a couple years ago though)
I might speak to my mate at a hire car place, and get him to pull one of the 5000's out of a Fiesta... =)
