I have a Nolan N104 and a Scalarider G9 and where I live they both pick up FM radio perfectly fine The Noland is a little better than the G9 but they both work on at least 4 stations. The 20S however gives me nothing. Even getting much closer to the transmitter I get very little and have to turn my head just to get a very slight signal. The speaker cable goes up over the top of my helmet and I even tried with the little side aerial up but no dice.
The FM radio on the 20S is not only extremely poor but is in fact useless to me and is one of the reasons I purchased it. Not the main reason but an important one.
