- Install with Ease: Cut a precise 85mm (3 3/8") hole in the panel and ensure a clearance of 70mm (2 3/4") behind the panel for proper gauge fitting. Simply place the gauge into the hole and secure it with screws. - Optimal GPS Performance: Position the GPS antenna flat with the black side facing up.
