There are way to many factors to take into account. generally a satnav will be closer to the mark but this depends on how good a signal it picks up and from how many satellites. most will give an accuracy reading if you look in the settings.
I have also found most speedo's will be roughly accurate to about 70mph and get further off the mark the faster you go.

Lord,
Grant me the WD-40 to move those things that are stuck, the Duck tape to fasten those things that are loose, And the wisdom to know the difference.
Amen
