Review on Fusion MS BT100 Bluetooth Dongle Marine by David Weis

Good product, easy to install and use. It needs a separate power supply to work. Purchase it separately or plug directly into the 12DC power supply on the hardware board or into the power supply area of the board. I gave four stars because the performance is poor. It's more of a pre-out type, and on my Bose radio at least, it takes a small power supply that I crank all the way up so the auxiliary input sound level through the RCA jacks matches volume when I switch between radio and auxiliary/ Bluetooth with a Fusion paired with my iPhone 7. The iPhone 7 volume needs to be turned up to about 90% in order for my Fusion and Buster combo to match my radio's audio output level.
