How to get national addresses in FIND address function?

I just bought the 66i. To quickly find a spot on the map, I assumed I could use the FIND Address function, but my version, bought in Norway, only shows regions Belgium, Germany, Luxembourg, Poland and The Netherlands. What if I wanted to use this function in Norway, or any other country that isn't on this list? I have downloaded and updated both the device and the topomaps, but nothing changed.

The weird thing is that using any of the POI features shows me an extensive list of everything in my nearby, including of course all street names, cities etc. I just can't search for them…
