Please see the link below for more information. https://bossaudio.com/product/mgr300b/ **Q: Besides the volume knob, what’s the difference between this and the boss 350b? There are no reviews anywhere** A: Hi Dedmon9 The 350b has an RDS Tuner, where the 300b doesn't. ("RDS" stands for "Radio Data System" and it allows FM broadcasters to send far more than just an analog audio signal out over the air waves. Using a 57 kHz "subcarrier," stations can transmit digital RDS data for reception by RDS-equipped FM tuners). ## Frequently Bought Together - BOSS Audio Systems MGR300B Marine Boat Stereo Gauge Receiver - Bluetooth, No CD DVD Player, AM/FM Radio, IPX5 Weatherproof, USB, MP3 - BOSS Audio Systems MRANT10 Weatherproof Marine Dipole Hideaway Antenna,Black - BOSS Audio Systems MR6B 6.5 inch Marine Stereo Boat Speakers - 180 Watts (pair), 2 Way, Full Range, Tweeters, Coaxial, Weatherproof, Sold in Pairs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/442830234-mgr300b-bluetooth-marine-stereo-gauge-receiver-no-dvd](https://www.desertcart.kg/products/442830234-mgr300b-bluetooth-marine-stereo-gauge-receiver-no-dvd) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-09-29*
