HI!
 
I am a one happy owner of V220 from Finland. I don't understand much of deutch but I'm reading this forum by using google translator. I hope you don't mind if I use english in here. I have found many interested topics which have helped me and I hope I can help you too.
 
Here is few pics from my V:
