I didnt spec the radio in my 2008 plus4 but I found that all the wiring was in place including the std connectors. In my car you could feel the round cut-out for the speakers under the trim in the footwells. My dealer fitted standard 10cm Pioneer speakers. I didnt want a visible antenna so I put a stick-on (Halfords) under the carpet at the edge of the parcell shelf and got good enough reception for the stronger stations. Hope this helps, Cheers J
