Our GPS speed sender just needs to be placed somewhere on your dashboard, and after a few seconds it sends speed information to the digital speedometer THROUGH OUR TFC DRIVE SWITCH (required).
This unit can also be used as a replacement for mechanical speed senders on other cars, as long as they are 8000ppm (pulses per mile).
Important note: You can switch the speed unit from MPH to KPH (kilometers per hour) for international use!
