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.
