    Why is the speed display incorrect on my APEXi Automobile Accessories unit?
    • C
      Cynthia HerreraAug 1, 2025
      If the speed display on your APEXi Automobile Accessories unit is incorrect, you should first re-check the Speed Pulse Setting and Speed Pulse Adjust Setting. Keep in mind that factory speedometers can have some display error; a difference of over 10km/h at 100km/h is not unusual. Also, if the speed does not display above a certain point, there may be another speed limiter device installed on the vehicle already. If so, remove that device for proper readings.
