    4.0 out of 5 stars Cheaper than stock, similar look to factory Kawasaki stereo.
    Reviewed in the United States on September 11, 2018
    Easy to install, great look for my 2017 Kawasaki Teryx 4. Initially was worried about the length of the mounting bolts being to close to the air intake in the dash. They do rub right on the box itself, but, grind them down about half inch or so and you are good. Installed perfectly in the factory position. Easy to navigate through options, and pretty easy to pair blue tooth to my phone. My only gripe would be that there is moisture behind the face plate. It only shows up after the engine is hot (Teryx runs a little hotter than most), so assuming it is moisture off of the engine. Overall i would definitely buy again and would recommend to anyone. If something changes i will report back, but so far so good.

    5.0 out of 5 stars Powerful and Bluetooth connects easily
    Reviewed in the United States on March 19, 2019
    I installed the MGR350B in the dash of my Ranger bass boat where I removed an inoperable round Lowrance Depth Flasher. It fit perfectly in the hole without any additional cutting. I used 8 gauge Boss amp wire kit and connected it to a small Sony Xplod 250w two channel amp and used 2 Boss three way 6x9's in carpeted boxed resting on the floor under the 2 steering/passenger consoles. This head unit's Bluetooth connects with my Samsung note 8 phone faster than any other device I have ever paired with it. There is plenty of full range sound and way more volume than I need. I feel I could easily connect 2 more speakers to this radio and amp combo and it would sound even better, but there is no need to, the pair of 6x9's are excellent. I have used boss speakers in 3 boats now and they all performed well. I recommend this radio if you need a round one. This is the first vehicle radio I have ever installed myself and the instructions were good, but I also watched a few YT videos to increase my knowledge before hand.
