Review on Black Pyle Round Waterproof Marine Stereo - 4x28 W Aquatic Boat In Dash Gauge Radio Receiver System with Bluetooth, AM FM, Digital LCD, USB, AUX, RCA - Includes Wiring Harness, Bracket - PLMR91UB by Benjamin Cleveland

I used to buy this radio from stock. I haven't installed it in over a year and it didn't work. I misplaced the cables and the connectors were the same so I ordered a new one. The one I got to replace the first had a different seating depth than the first. The hole cut looks more like 3" than 3.5". I cut a hole for 3.5" based on the list. This would have worked if the depth hadn't increased from the original unit. So I used a piece of PVC adapter to give the radio depth and a bit more diameter Worked well. There is a bit of noise in bluetooth and the range for BT is terrible. 10ft. If you are on a boat this would probably be fine. But mine is on an off-road trailer. Get out of the trailer, to get something out of the truck and it will lose the BT signal. Pyle has other options with a 30ft range. You can look at them if the problem is with the range. But really, it's all really picky for a $55 radio It's definitely worth $55.
