I'm currently using a non Sena half helmet that has a 20S installed on it.  I recently purchased the new Sena Cavalry half helmet for my wife.  The 20S will say music sharing is on, but nothing happens on the Cavalry helmet.  I'm using the latest firmware and I have also tried using the older firmwares.  I have used the fault reset button and the factory reset on both units and it still won't work.  The odd thing is that she can share music from the Cavalry helmet to the 20S every time with no problems. The sharing works perfect with the Cavalry helmet being the source.  The only problem with that......I'm not in control of the music!  Just wondering if anybody has had the same issue or anyone knows how to fix this issue?
