I want to on fm without Head phone...i need code.

If you mean Nokia 2310, I don't think it's possible to play radio without headset connected to the handset. I don't believe, nokia has ever developed such a model and moreover it's impossible to play radio on nokia phones via bluetooth. If you mean other model, do let me know. Or is there any other application installed on your phone to run the radio? But in fact the handset needs the headset to run radio, so that i'll act as an antenna. Somebody uses the cut-out jack of the headset to play radio. You can try a trick, play the radio, put on the speaker (loudspeaker), then remove the headset, if it's working you are lucky. But even with Nokia N95, it's not working.
If you are sure that you are asked a code to access the radio without headset, let me know with more details.
Thanks.
Good luck.
