Style: MGR350B Receiver
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

Installed on a 2009 rzr. Easy to install and works flawlessly with my phone via bluetooth. I haven't checked to see how the USB works on it nor the radio as I don't have an antennae yet however it is hooked up to an amplifier with an 8" sub and two clarion speakers and it sounds amazing when riding with the loudness of my sxs. There's not much to say other than it's a very good option for probably a boat and certainly a sxs. While I had to modify (cut out a spot) and it's not flush but that's because the rzr is from 09 and wasn't built to have a stereo option. But it works great. I think it's an inexpensive option that will certainly perform to most people's standards provided they have decent speakers. It's loud, louder than most sound bars for 3x the cost.

Installed this radio and speakers into my boat in less than 1 hour. Awesome product with awesome results. It came with easy to follow directions the quality to really good. Bluetooth function works perfect, speakers have great sound quality, and offers a solid fit into my center console.

Things to know that are confusing about the product description, reviews, and QA on this page: 1 - The round one does not come with an antenna. An antenna is not mentioned anywhere on the box or in the manual. I do not know why there are so many QA questions stating that it DOES come with an antenna. 2 - The switched-power-on wiring is pointless; the unit has non-volatile memory, so it doesn't lose clock, bluetooth or radio settings when completely disconnected from power. I'd suggest you wire both power leads together. This is really important if you use a battery switch or breaker panel to disconnect everything when you are away from the boat. Other than these things that I wish I could have confirmed before I bought it: It's fine. It sounds okay, the interface and menus are okay, the installation instructions are okay. It feels pretty cheap in operation, but it does function. I installed it immediately and it has had a week of being in very, very hot and humid conditions inside my boat and there have been no issues. When it dies, I would be 50/50 on replacing it with the same model or spending more for a different design. Power draw seems very low in operation.

The sound from this is so much better than my older Jensen. Extremely easy to install. The bluetooth connectivity was the most important feature for us and works great!

I am somewhat of an audio file in my home and car. So, I wasn't expecting much out of this product I didn't want to put a lot of money into the system. I was presently surprised. The sound quality is pretty good; descent amount of base and clarity isn't bad. Now I haven't had it on the water yet, I've only listened to it in my driveway, but I don't think my opinion will change.
