and, MPH (40) read as KPH converts to (24.8).

The figures and the maths supports this. But why?
Has anybody got a solution/reason for this.

In regional settings i have selected "miles/feet".
The indicated road speed ,with no speed cameras showing, is correct. As soon as a camera is detected it shows the camera speed wrongly. The speed it shows equates to the camera
registering the correct[mph] speed assuming it is in in Kph and then iGO converts this value to its mph equivalent.
