- Easy Installation: Cut an 85mm (3 3/8") hole in your panel and ensure a 55mm (2 3/16") clearance behind it. Simply mount the gauge by placing it in the hole and securing it with screws. - Optimal GPS Performance: Securely mount the GPS antenna with the black side facing upwards in a flat position. For best results, position it outside or on the inside front windscreen to ensure an unobstructed view of the sky. Connect the antenna cable to the designated socket on the gauge without cutting the cable. - Quick Signal Acquisition: Experience fast signal reception with an initial acquisition time of approximately 30 seconds, reducing to under 3 seconds thereafter. Signal strength improves with a clear sky view. If you encounter issues, check all connections and restart the device. - Comprehensive Display Functions: The gauge provides real-time information including current speed, adjustable odometer, trip meter, Course Over Ground (COG), and voltmeter readings. Easily switch between KM/H, KNOTS, and MPH using the back button. Use Scenarios: 1. Marine Applications: Monitor your speed and distance traveled on a boat, ensuring accurate navigation with the COG feature. 2. Automotive Use: Enhance your vehicle’s dashboard with precise speed and odometer readings for improved driving efficiency. 3. Recreational Vehicles: Track performance metrics on off-road vehicles to optimize usage and fuel efficiency. This durable and reliable gauge is compatible with a variety of vehicles and ensures you stay informed on crucial travel metrics, making it an essential addition for any driver or navigator.
