Virb and GSC10

I've just re-paired my Virb with the GSC10 on one of my bikes and I notice the Speed information from the GSC10 displays on the Virb as well as the Cadence but there is no means of calibrating the wheel size. I presume this must be done by cross referencing with the GPS.
Can anyone confirm this?

The sooner we get a separate Virb forum the better!
