- Precise Installation : Cut an 85mm (3 3/8') hole in the panel and ensure a clearance of 55mm (2 3/16') behind it to fit the gauge securely. Simply insert the gauge into the hole and fasten it with screws. - Optimal GPS Antenna Positioning : Securely mount the GPS antenna flat with the black side facing upwards. For best results, place it outside or on the inside front windscreen to ensure a clear view of the sky for satellite signal acquisition. Connect the antenna cable to the gauge without cutting it. - Quick Signal Acquisition : Experience rapid signal detection, with the initial setup taking about 30 seconds and subsequent signals acquired in under 3 seconds, especially with an unobstructed view of the sky. If signals are lost, double-check connections and restart the system. - Comprehensive Monitoring : The gauge displays current speed, an adjustable odometer, trip meter, course over ground (COG), and voltmeter readings, tailored for better performance. Easily adjust the unit of measurement between KM/H, KNOTS, and MPH using the back button. - Versatile Applications : Ideal for marine vessels, off-road vehicles, and motorhomes, this gauge enhances your driving experience. It assists with navigation, distance tracking, and vehicle performance monitoring. - Reliable Performance : The gauge is designed for consistent reliability, helping you stay informed on speed and distance while ensuring accurate readings for better decision-making on the road or water. With streamlined functionality, optimal compatibility, and user-friendly features, this gauge is a must-have for anyone looking to enhance their driving experience with precision and convenience.
