I have the 2, not the 2 XL, but they should be similar. I have no problem with Bluetooth anything - car, speakers, earbuds ...
Sometimes, it takes reading the instructions line by line and following them line by line (and I've been designing communications equipment for half a century, both hardware and, when it became available for the public, software - and I still sometimes have to just play dumb and follow the instructions - they don't make any sense, it shouldn't work the way the instructions say, but when I follow the instructions, it does work - come on - hold the volume down button until the light flashes?)
