Got my bluetooth add on module yesterday and tried it out. Connect it, pair up a device (very simple) and adjust settings as needed and off you go. I connected it to my phone first since that was the quickest thing to pair up and it worked well. It shows up as an input on the UMC-200 so you can have it set to manual selection or have it automatically switch to that device when bluetooth is active. The one funny thing was that the display isn't long enough, so it shows as "Bluetoot" LOL
