Product Description:
ALWAYS have an accurate speed reading with this unit. Changing your gear size or tire size on your vehicle can alter your speedometer’s speed reading, sometimes up to 10-15 MPH. Not anymore! This module gets your speed reading from bouncing a signal off of satellites that mark your global positioning instead of getting readings from your transmission. This means that you will always be accurate and always be calibrated, no matter what changes you make to your vehicle (tire size, gear size, aftermarket transmission, etc.). Works with any electric speedometer.
