Review on 🔊 Marine Stereo Receiver: Waterproof Bluetooth MP3 Player, AM FM Radio & USB – Perfect for Streamlining Music on Boats, Golf Carts, ATV, UTV, and Spa Hot Tubs by Philip Berry

Great little compact 'waterproof' not 'waterproof' stereo. Easy to install if you are prone to electricity. The directions don't help much other than letting you know what the wires are for. The trick is to program the setup. You can't store the stations in the order you want like you would with a standard in-dash stereo. All you have to do is scan the stations being played and they will be saved automatically, and then you can use the arrow keys to move from one preset station to the next. A 3.5 inch hole needs to be drilled.
