Speedometer

I have a question for all of you knowledgeable people, my speedometer shows 5 km/h too little and I find that really annoying. Is there a way to calibrate it in OrBit?

I've change my wheels from 225/50 R17 to 245/35 R20

017 from 17 (225/50 R17) to 1A (245/35 R20)
this does not change the speedometer but as necessary to get rid of error messages
018 from 44 (2040mm) to 58 (2140mm) 
after this setting the speed was off as it was from factory ~+5% more shown than actual

What do you mean by that? If your tire size and tire rolling matches to installed tires, it should show you the exact speed. 
I tested my speedometer with my pro-GPS (not car's and not phone) and it always shows the same speed what car's speedometer shows!

Not mine, not in this car and not in any of my v70 and not in any car i have had. Maybe it's because market. I live in Sweden and here, as far i know, all car not show real speed, it's about 3-5 km/h to little, my is 5 km/h.

It might be state regulation then.  Try with 160 INSTRUMENT CLUSTER CALIBR.
