Gravity MGR-208BT Single DIN Marine CD Receiver with Bluetooth

The Gravity MGR-208BT is a Single DIN marine receiver designed to bring multiple music sources to a boat or yacht dashboard. It combines AM/FM radio, CD playback, Bluetooth streaming, USB, SD card, and auxiliary-input playback in one in-dash unit. This makes it a practical replacement or upgrade for vessels that need straightforward entertainment options without adding separate source components.

Built-in Bluetooth with A2DP streaming lets compatible smartphones, tablets, and other supported devices send music wirelessly to the receiver. A front auxiliary input, front USB port, SD card slot, and CD mechanism provide wired and media-based alternatives when wireless playback is not preferred. The unit also supports MP3 playback for digital music libraries.

The MGR-208BT is rated for 300 watts maximum output and uses a four-channel audio configuration. Its sound controls include preset equalizer modes for Rock, Classic, and Pop, allowing users to choose a simple tonal starting point for different music styles. Built-in anti-shock technology is included to help maintain playback stability in a moving marine environment.

A detachable faceplate with colorful LED illumination gives the receiver a distinct dashboard appearance while allowing the control panel to be removed when the vessel is unattended. The large volume knob is designed for quick level adjustment, which can be useful when operating in open-air conditions. Six radio presets provide convenient access to frequently used stations.

This receiver fits a standard Single DIN installation and can serve as the central source unit in a basic four-channel marine audio system. It is suited to installations using compatible marine speakers and a 12-volt audio electrical system. An RCA output is provided for adding a compatible external audio component where appropriate.

Design & Installation

The MGR-208BT uses a conventional in-dash Single DIN receiver layout with a detachable colorful LED faceplate and a prominent rotary volume knob. Its front-panel design places the auxiliary input and USB connection within easy reach, while the CD slot and SD card slot expand playback options. The included control format is button-and-knob based rather than touchscreen based.

Install the receiver in a standard Single DIN mounting location using appropriate marine-grade wiring practices and compatible speakers. Connect it to the vessel's 12-volt power, ground, antenna, and speaker wiring, then pair a Bluetooth device or connect media through USB, SD, CD, or the front auxiliary input. Verify speaker compatibility and wiring polarity before powering the system, as detailed impedance and RMS-output specifications are not published for this model.
