Hi everybody,

I'm trying to find out if we can calibrate the real speed displayed on my GO 620. I've noticed that there is a difference of 5 km / h (Metric System) below that displayed by my car ?

Thank you

    All car speedos will read high. One reason is to ensure that manufacturing tolerances don't lead to a unit reading low and leaving the driver inadvertently breaking the speed limit.

    tonygr is right.
    You can also check it with a smartphone app

    So should I consider the speed indicated by my GPS as the right and accurate one, because it is calculated via satellite information vs map position, exact ?

    Thanks,

    Yes, the speed calculated by the GPS will be much more accurate than the speedometer in your vehicle.

    I wonder if the police officer who pulls you over for speeding will buy that..when you tell him your GPS showed that you wasn't speeding..?!? Doub't it

    Hi
    @jatco

    As police patrol cars have calibrated speedometers they would see the same speed as your GPS....
