AutoMeter Sport-Comp 5″ GPS Speedometer (0-225 KM/H)
Ultra-precise, plug-and-play 5-inch metric GPS speedometer gauge for performance road and race vehicles.
Product Overview
The AutoMeter Sport-Comp 3983-M GPS Speedometer combines classic race-proven instrumentation aesthetics with advanced high-speed satellite signal processing. Eliminating the need for cable drives, wheel sensors, or tedious pulse calibrations, this 5-inch metric gauge runs off basic power and ground connections. Included with the instrument is an ultra-compact 10Hz omnidirectional micro antenna that samples data 10 times per second for instant velocity feedback. The built-in Rally Nav display presents comprehensive driving metrics including cumulative distance, dual trip odometers, time/date, compass heading, GPS coordinates, and peak speed recall.
