Auto Meter continues to expand their selection of speedometers equipped with their award-winning integrated GPS technology. After the incredibly successful launch of fully integrated GPS into the legendary Sport Comp, Ultra Lite, Phantom, and Street Rod lines, this exciting tech is now available in Carbon Fiber (4780, 4781), Traditional Chrome (2480), and Z Series (2680). These highly advanced GPS Speedometers require no interface with your vehicle aside from power and ground. An ultrafast, omnidirectional micro antenna is included for true plug-and-play functionality and never requires calibration. Even changes in gear ratio or tire and wheel size have no effect on these units’ pinpoint accuracy. Configurable Rally Nav display shows odometer, trip odometer, time/date, GPS coordinates, heading info, compass, and peak speed recall. Quite simply, these are the easiest, most accurate speedometers available.
