Hertz HMR 20 Marine Audio Receiver with Bluetooth, USB and DAB Ready

The Hertz HMR 20 is an all-in-one marine source unit designed to elevate every voyage. Built to withstand salt air, spray, and sun, it combines rugged durability with intuitive controls and studio-grade audio tuning. Whether you’re anchored at the dock or cruising the open water, this receiver delivers seamless access to entertainment without compromising reliability.

Rugged Marine durability you can trust

Designed specifically for vessels, the HMR 20 carries IP66 protection for water and dust resistance, plus ASTM-D4329 UV resistance and ASTM-B117 salt fog operability. In other words, it stays resilient under harsh sun, spray, and long season after season use, so you can rely on it through every boating adventure.

Crystal-clear visibility and effortless control

The heart of the user experience is a 3-inch full-color TFT IPS display that remains clearly legible in bright daytime conditions. Large, tactile buttons and a multicolor button lighting system make it easy to navigate while underway, even in rough seas. The display and controls are arranged for quick access at the helm, so you can keep your attention on the water.

Seamless connectivity for modern boat life

Stay connected with a suite of versatile inputs and wireless options:

• USB 2.0 for quick device playback and charging on the move.
• Bluetooth 5.0 for reliable wireless audio streaming from phones and tablets.
• Digital Audio Broadcasting (DAB+ Ready) to access a wide range of digital radio stations with crisp sound.
• AM/FM with RDS where available, so you can tune into favorite stations and see program information on the go.

All of these options are packaged in a marine-optimized chassis that keeps signal quality high even in reflective environments, ensuring your tunes sound as good as they do on land.

Premium sound, tailored for life on the water

The HMR 20 offers a refined audio experience crafted by Hertz engineers. It includes 4 customizable EQ presets that adapt the sound to your cabin, cockpit, or helm space, helping speech clarity for weather updates or boosting the lows for a weekend soundtrack. Two independent stereo outputs let you create distinct listening zones—perfect for keeping the helm area clear of cabin noise while still delivering immersive audio to the cockpit or lounge.

Two zones, one clean install

With 2 pairs of stereo outputs, you can independently manage two listening areas without a separate amplifier setup. This means you can keep the captain’s cabin focused on navigation audios while passengers enjoy a tailored music experience in the stern or bow seating area. It’s a practical, plug-in-ready approach to marine audio that reduces clutter and wiring complexity.

Real-world value and practical tips

• Day-to-night versatility: use the daytime-optimized display for on-deck visibility and switch to lower brightness at night for reduced glare while docking.
• Cruise-friendly tuning: save a “Cockpit” EQ profile for open-water cruising and a “Cabin” profile for evenings at anchor.
• Maintenance-friendly: built to resist salt fog and UV exposure, reducing service intervals and extending component life.
• Future-ready: DAB+ readiness ensures you’re compatible with evolving digital radio formats without replacing the core unit.

Who benefits most from the HMR 20

Boaters who demand reliable entertainment that won’t fail under sun or spray will appreciate the HMR 20. It’s ideal for sailors, sport fishermen, pontoon operators, and coastal cruisers who want:

• Robust marine-grade electronics that survive repeated exposure to salt and sun.
• Flexible listening layouts across multiple boat zones without extra gear.
• Modern connectivity—Bluetooth for convenient streaming, USB for quick device pairing, and DAB+ readiness for premium radio content.
