Gravity MGR5 Marine Digital Media Receiver

The Gravity MGR5 is a 12V marine digital media receiver designed to bring music, radio, and compatible media playback to boats and other exposed-vehicle applications. It combines Bluetooth streaming, USB, SD card, AUX, and FM radio sources in one compact receiver. Its 4.1-inch LCD display provides a central interface for source selection and video playback.

This receiver is intended for boat, ATV, motorcycle, RV, and car installations where a weather-resistant entertainment source is needed. The front-panel controls, illuminated buttons, and included remote help make source and volume adjustments more convenient in varied lighting conditions. Bluetooth support allows a compatible phone or media device to stream audio wirelessly.

The MGR5 is rated at 200 watts maximum output, specified as 50 watts across four channels. Dedicated subwoofer level controls allow the bass output to be adjusted from the receiver, while built-in equalizer presets provide quick tonal changes. This makes it suitable for systems using four speaker channels and, where applicable, a compatible amplified subwoofer setup.

For media flexibility, the receiver supports USB storage, SD cards, an auxiliary input, Bluetooth audio streaming, and FM radio. The LCD screen also supports video playback from compatible media. Physical controls include a rotary power, select, and volume control along with dedicated source, tuning, menu, and playback buttons.

Its IPX5 water-resistance rating and multi-color button illumination suit marine and powersports environments where splashes, dust, and low-light operation are considerations. The receiver uses a 12V DC electrical system and includes a wiring harness for installation. It can serve as a replacement media receiver or as the source unit for a new multi-speaker marine or recreational-vehicle audio system.

Design & Installation

The MGR5 combines a compact receiver chassis with a 4.1-inch LCD display, tactile front controls, and multi-color illuminated buttons. Its weather-resistant construction is rated IPX5 for exposure to splashes and light rain, rather than submersion. The design is intended for marine, powersports, RV, and automotive environments using 12V DC electrical systems.

Confirm available mounting space before installation using the listed approximate front-panel width, chassis height, and chassis depth. Connect the supplied harness to constant 12V power, accessory power, ground, speaker leads, and any applicable remote-turn-on connection; disconnect vehicle power before wiring. Use the unit as a standalone four-channel receiver or as the source component in a system that includes compatible external amplification and a subwoofer.
