I live in the US but have a German 2013 Forester Activ (diesel) that I keep over there for road trips etc. I am heading over in a few weeks and want to bring some things over - a new audio head unit, maybe some speakers, and the rubber mat for the cargo area. Anybody know if the measurements of these are standard across regions? I kind of expect the head unit would be pretty standard, but how about the cargo bay? In other words if I ordered a cargo bay floor mat from Amazon for a 2013 US forester would it fit in the German one? Same thing with the head unit etc.
