AutoMeter GPS speedometers are capable of working with most aftermarket GPS antenna/receivers or with AutoMeter's 5283 GPS antenna. AutoMeter's ultra fast, omnidirectional micro antenna is available separately for true plug and play functionality and never requires calibration. Configurable Rally Nav display shows odometer, trip odometer, time/date, GPS coordinates, heading info, compass, and peak speed recall. Quite simply, the easiest, most accurate speedometer available.
