JBL PRV170 Gauge Style Stereo Receiver AM/FM/BT/USB - 4 x 45W
Installed on my boat 3 months ago.  Have been on the water twice.  USB, Aux ports quit working.  Bluetooth quit working.  Only sound that comes out of it now is the radio.  Sound is great, easy install, but terrible quality.  Would not waste my money. But now I have a gauge size hole in my dash that I cannot replace with a different unit.
