Installed this in my old bowrider speedboat and love the small form factor. The radio produces great sound and has quite reasonable output to my Polk audio speakers. Unfortunately after less than 2 weeks of being installed, the lcd on the radio now periodically flashes random characters.. This only lasts a few seconds, but is disconcerting. The radio also runs warm, which is unavoidable given it’s small size. Just be sure it has room to breathe. One other item of note is that plugging your cell phone into the usb connector forces the radio into usb mode, but does not read from a cell phone. I am now streaming from my tablet via bluetooth and charging it from a separate lighter socket.
