Features & Specifications




MB Quart GMR-3 180 Watt Bluetooth Marine Digital Media Receiver

MB Quart’s GMR-3 marine digital media receiver isn’t big (it fits in a standard gauge opening), but it gives you big-time performance and tons of connectivity options. This rugged multimedia receiver packs a ton of features into a compact design that’s made for the outdoors. Built-in Bluetooth makes music streaming easy and awesome.

Apple control and more

You can tune in to AM/FM radio, of course, but the big deal is built-in Bluetooth® that lets you stream music from your smartphone or other Bluetooth-enabled device. The GMR-3 is Apple-ready too, so you can access the iTunes collection on your iPhone®, iPod®, or iPad®. You can also use the rear aux input for your music player, or plug a thumb drive into the rear USB port to enjoy your favorite music.

Expand your system

The GMR-3 also includes a pair of rear-mounted preamp outputs, making it easier to add on an MB Quart marine amp. The LED display gives you the info you need, while the watertight, UV-resistant face and big, easy-to-use buttons will stand up to the rigors of marine use. The carbon fiber-look face will bring some extra style to your boat, too. You can also add up to two MB Quart wired marine remotes and control your music from anywhere.

GMR-3 Features:

  • Marine Grade Protection / IPX Rating: Meets or exceeds the American Society for Testing and Materials (ASTM) standards. LIFE SHIELD: This product has been designed and tested against the elements. Waterproof, dust proof, snow proof or shock proof. Built to handle the outdoors.
  • Apple Control: Quick control and access of iTunes collection with iPhone, iPod and iPad.
  • Source Type: AM/FM/Bluetooth Enabled Gauge Mount Radio allows all access to radio stations and content from Bluetooth enabled devices.
  • Input Types: Bluetooth, RCA, USB: Nearly nothing the device can not play. Cassettes and 8-tracks not withstanding.
  • Control Buttons: Large & Waterproof Play/Pause, Tracks Forward/Back, Volume Up/Down and Power On/Off are all protected from the elements with the large waterproof button. Their size and space also makes them easy to operate with riding gloves on.
  • Bluetooth Connect: Bluetooth Connect allows your phone or other Bluetooth enabled device to be quickly paired to the controller without a complicated pairing process.
  • Secure Simple Pairing: Quick and secure wireless connection between your Bluetooth enabled device. This reliable connection is impervious to outside interference, providing a lock-tight connection to your audio system.
  • Quick-Pair: No more frustration with trying to pair. When the unit powers up, it immediately connects to the last device connected. For a first time connection, you only have to select “MB Quart” from your Bluetooth menu and you are connected, QUICKLY.
