    Nice little radio. Connects easy and automatically each time. Nice sound and simple to install and operate. No complaints.

    Worked great for my portable waterproof Bluetooth speaker box. Made the build so much easier, especially having flexibility with the number of speakers I use and no need for an external amp. Very good sound, nice and loud and looks fantastic in a speaker box. Extremely easy to connect.

    got this for my pontoon where the original quit working. someone at the shop says the screen goes out on a lot of units, so I picked this one as there is not screen to get water into. also, saw no use for the radio feature of the original unit, so like that this is primarily a Bluetooth system. I don't know the technical reasons, but this unit plays louder and sounds better through the same speakers and stays connected to my phone when I switch the engine off moving the key into accessory power mode when we park and play.

    quite working randomly after a few months of being installed in my UTV. It will power on at times, light up and be very glitchy, now it does not turn on at all. I have power, the fuse is new and the only issue is the radio itself. Tons of reviews stating the same thing, my advice is purchase a quality product like Rockford Fosgate. I have had Rockford brand products in my boat for years and never had one issue. DO NOT BUY THIS PRODUCT, unless you like trouble shooting and replacing electronics.

    I've only had it installed for a couple months now, but I'm very happy with it. I am not using an amp, only this head unit, and the sound is crisp and clear all the way up to 100% volume. Of course I got some decent speakers. So far it's great
