JL AUDIO MMR-40: Full function NMEA2000 Network Controller with LCD Display | 99910

The MMR-40 is a NMEA 2000® network controller engineered to add full-function, auxiliary control to MediaMaster® source units. Once connected, the MMR-40 automatically recognizes the host MediaMaster® source unit and will then mirror all host source unit controls and screen info onto the MMR-40’s full-color, 2.8 in LCD display, resulting in a complete MediaMaster® user experience. The MMR-40 is equipped with independent display theme and lighting controls for maximum mounting location flexibility, regardless of the settings on the host source unit. Engineered for real-world marine (and many outdoor) applications, its weather-proof (IP66-rated) chassis is built to withstand the harshest environments.
