Can you stream from your headset to your wife? We have a Sena SMH10 system that BT to the bike and I stream the music through my headset to my wife. Equally my wife can pair into Device on the bike but chooses not to.
BTW when I initially purchased my TTSE way back in Apr 2013 the dealer included a Scala Team Pro system. We quickly found that it couldn't effectively pair to the bike as it didn't have A2DP connectivity (e.g. multi media).
