I wanted to add Bluetooth streaming to my Sharp GF555 and My Hitachi 3d80 Boomboxes but i didn't want to start soldering onto the board of the box. I managed to find this little dongle that is battery powered and connects to the line input. Its small enough to stow away in the battery compartment or stick to the back of the boombox with double sided tape. Very good sound and works great. Cost me £9 on Ebay
