The CMM-20 is a high-performance, dual-zone source unit with built-in power and versatile audio features designed for marine applications.

Equipped with a variety of audio source options, the CMM-20 features a global, digital AM/FM tuner with built-in NOAA weather radio (US only), Bluetooth audio streaming, a USB 2.0 input for playback from your USB storage device (with 1A charging) and an analog auxiliary input, all designed to deliver non-stop sound, no matter how choppy the seas may get.

A rugged, weatherproof (IP66 rated) chassis houses a 2.37-inch (60 mm) LCD display with dimmable control for nighttime viewing. When in motion, you'll appreciate the large controls and uncluttered user interface with big text and backlit buttons.
