Boss MR752UAB Marine Receiver

Covered CD slot, USB port, and auxiliary inputs

Just because you're out on a boat doesn't mean you have to put up with a weak, old stereo. This marine-rated receiver from Boss gives you the sound and performance you want at a value price you'll really like.

Built for boating

Boss designed the MR752UAB CD receiver for marine use, with a UV-resistant exterior that resists fading and a conformal-coated PC board that resists corrosion. The fold-down faceplate features a single-line alphanumeric-text display that's easy to read. When you leave your boat at the dock, you can slip the detachable face into the included hard plastic carrying case (a soft case is sold separately). This radio will even retain your presets when the battery is disconnected.

Lots of ways to enjoy your music

Bluetooth capability lets you enjoy convenient hands-free calling and music streaming with any compatible phone. Listen to your favorite CDs, play music stored on a USB drive or SD card, or plug your MP3 player into the 3.5mm aux input. All the openings are protected from salt and spray when not in use, of course.  And you can control all receiver functions (except for Bluetooth) with the included remote.

Installation note: This marine radio is water-resistant, but we recommend mounting it in a water-resistant enclosure or using a cover for best performance.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.

    Programmable Turn-On Volume: You can set the head unit to turn-on to a pre-defined volume level (0-45) every time you power up the radio.

    Key Beep: The in-dash head unit provides an audible beep to confirm button operation. This function can be turned On or Off.

    RDS AM/FM Tuner: The Boss MR752UAB features a built-in RDS AM/FM tuner.
