I always found it annoying that every time I turned the boat off and restarted it, the Fusion stereo would shut off and I would have to re-pair my phone to the stereo, ridiculous! A little research and spending $56 on the Fusion BT-200 bluetooth adapter, upgrading over the BT-100 that came with it, and BAM! Whenever I re-start the boat now, it automatically pairs to the previous device and song! The upgrade also provides song info on the head unit and the remote. The other great feature is that is a simple plug and play, done! Boat is winterized, always looking for an excuse to get in my boat (stored in my garage) and have a beer! Maybe I will vacuum it again.....
