Hey Scotts Billy,

i got a mail form support with my answer, but in the meantime i had figured it out by myself ...

Make sure that the radio is shown in your screen (View -> Gadgets -> Radio)
In the same menu you can choose the mode (View -> Gadgets -> Radio Mode (Gadget Only))

I hope it will work for you, because i use G3.5.

Grtz,
Menno
