The MB Quart GMR-MIC is a waterproof microphone built to drop into a standard Carling-style switch knockout, so it fits the dash cutout you already have instead of demanding a new one. Its IP67 sealing keeps the connections protected from spray and rain, which makes it a natural fit for boats, side-by-sides, and other open-cockpit vehicles.

The 3.5mm audio mini jack plugs into MB Quart and universal source units, letting you take calls or give voice commands without reaching for a handheld mic. The compact black housing measures 1.625 inches high, 0.25 inch deep, and 1 inch wide, and the cutout needs 0.8 inch of width by 1.3 inches of height.
