I also have a pigeon pair and love them. Just to add something further to the previous notes.
I don't have a uhf so I haven't gone the sr10 road as yet.
However, I have an ipod, Garmin Zumo 390 and an iPhone all running simultaneously on Bluetooth and work absolutely great.
I used the PC app to program my local FM stations. Once I ride beyond the Radio range in Sydney, I give the phone button three very quick taps and it automatically searches for the strongest signals and you can then rotate through them one at a time, once you turn it off, it reverts back to your previously programed stations which is perfect for those day trips.
I agree that the sound is phenomenal and it has become an indispensable part of my kit.
