## Description

BOSS Audio Systems MGR350B Marine Boat Stereo Gauge Receiver – Bluetooth, No CD DVD Player, Built-in 4 Channel Amplifier, Weatherproof, USB, USB Charging

Review: جيد
Review: after slightly shortening the U-mounting bracket to prevent interference with a dashboard cable harness the mechanical installation is quite simple and easy. However a bullet proof electrical installation is time consuming and complex if done properly, (common to all radios in this class) I used automotive type , (offroad vehicle!!!!) waterproof connectors for all wiring so dashboard can be removed, added master on off switch to prevent any battery drainage on my UTV and also installed a marine type high gain wip antenna with excellent results. The Radio is powerfull and delivers surprisingly good sound. The push buttons are somewhat small, forget operating radio when wearing gloves. I pipe my music in via my Samsung S7 or my I pad, works flawlessly. The little USB plug is a bonus. If you are in the market for a small 3" diameter radio give it a look, I like it and would buy again

Boss Audio Support Team

**Q: I see it's a 3 year warranty on the stereo?? I got one almost a year ago and the screen blacked out after 6 mounts what and who do I get a hold of to**
A: You should check your order and either the seller or BOSS would be my guess.

**Q: How long are the USB and aux input cords?**
A: 12 inches

**Q: Why is the one without speakers more expensive? We have speakers.**
A: No idea.  I ordered the one with speakers (only a few dollars difference), but only used the head unit.  Saving the speakers in case things change later and I want to install them.

*by F***Z on 9 September 2025*

I got this for my Polaris RZR to run my system that includes four 6 1/2” and one 8” subwoofer along with 2 kicker amps, I replaced using the ride command (stock radio) and it woke up my audio system. The quality is good, brightness display screen. Easy to operate being that the buttons are a good size. Has features like builtin EQ, Bluetooth. It’s a good value for your money. I recommend this 10/10
