Our GPS Speedometer works with any industry standard 4000, 8000 or 16000 pulse per mile or programmable speedometer. It can be wired directly into your existing speedometer and needs no additional sensor from the transmission to operate. The unit comes with a GPS receiver, omni-directional 4 ½ ft. antenna, and microprocessor that continuously converts GPS signals into a pulse stream that then replicate the output from you existing, mechanical speed sensor but with GPS accuracy. This combination of GPS technology and our own innovative engineering and electrical design allows for high-accuracy readouts. You do not have to worry about inaccuracies due to changes like different tire sizes or rear end gear ratios ever again!
