Question about UE Wonderboom

I also had this problem. You have to buy an adapter that outputs BT... BT put from radio. Personally, after several weeks of searching, I came across the following and installed it like this... wonderboom always connected to a usb source for charging. The radio (internetradio ((many more stations and connected via lan)) and dab+) connected to wonderboom with chinch cable.
. Sound perfect... stationary... wonderboom in the bathroom because it is waterproof... otherwise... any dab+radio with bt out adapter... costs a lot... since i had internetradio maö i don't have a radio in my house anymore... hope the answer is enough... enjoy or keep searching...r
