Hi, I have downloaded the bmw Motorrad ap to my iPhone, I have paired the iPhone to the TFT on the GSA , can now see all my contacts etc then paired Schubert’s c3 pro as rider headset nice and can now listen to amazon music and control volume track etc via wizzey wheel again . Then paired my wife’s Schubert’s to tft as pillion headset, no music to listen, only comes through on mine. Anyone know if there is a way for the music to go to both the paired headsets? Otherwise can’t see the point of pairing the second headset?
