Default [Q] Bluetooth headphones and FM radio


I own a bluetooth headphones that works perfect with music players, but I have problems with the FM radio. When I turn it on, it says I need a normal wired headphones to act as antenna. That is OK; I plug one, and it starts the radio, but when I make a bluetooth connection with the headset, radio says it is incompatible and can not run with bluetooth connectios.

I have also probed Spirit FM radio that says it is compatible with bluetooth, but I have not been able to get it to work.

Does anybody get it to work a bluetooth headphones with FM radio?

(I want to use FM, no stream internet radio. It eats my data plan as I listed to radio a lot).
