I didn't use the blue tooth function on mine but I can't say enough good about the Fusion stereo I installed. Very versatile, upgradeable with plug and play components. Sirus -ready, WX, you can tie them into NEMA 2000 electronics, blue-tooth stuff, you name it. They are really made for the marine environment and come with a 4 year warranty. They're not just a car stereo with a water-repellent spray on the chassis. They're a few bucks more than the run-of-the-mill stuff but a quality unit. I recommend you check them out before you buy.
