Isn't it the other way around? I think it is, since speedometers in cars are legally (obliged by law) showing faster speeds than the real speed

I guess there is something wrong with iGO settings or number of satellite involved for the car position and speed is not enough. actually we need some expert here to identify what is the problem!!!
about the speed yes I'm sure about the difference.
