While using the trailer last weekend, for the longest time we were unable to get the Bluetooth stereo to connect to my wife's phone. After resetting and playing with different options we still could not get it to connect. It was only then I realized that the stereo was still connected to my phone and therefore would not show up as a device on my wife's phone. The Furion stereo in your trailer model, the same model as mine, can only connect to one device at a time. I'm guessing it's most likely connected to a second device that you may have gotten about?
