MGH30BT - Digital Media Receiver with 3" LCD and Bluetooth®

This flagship, gauge hole-size receiver features a large 3” TFT, multi-line, full-color LCD. The built-in Bluetooth supports audio streaming and player control profiles. The receiver is IPX6 waterproof to withstand heavy splashing and rain. Direct control for iPod and iPhone devices is available via the rear USB input. Media playback from select Android devices is also available via USB. One pair of RCA aux inputs and preamp outputs are also located on the back of the receiver. The zero current draw memory back-up saves the boat’s battery when idle.
