Accord 6 cd head unit - aux in adapter

I've got a european Honda accord 2005 model. It has the 'premium' sound system and the 6cd in dash head unit. I'm trying to get an aux in
adapter for it, but it's proving difficult to source here in the UK.
Does anyone know if this is the same head unit used in hondas in the US?
What should I look for on the head unit to confirm similarity with the US head units?
