I reached Barcelona, my destination. Here I am riding with a pillion without cuts for speakers in her helmet. It seems to me that it is not really possible to add a normal com there.
Is there a way to use the pillions phone (using the phones headset) to connect to my Sena comm.
I have tried to pair the Sena to the pillion phone in "universal mode", but the pairing fails. I have also tried to use the app BTtalk, but as I see it is uses internet, not BT (in spite of the name) and it works far from stable.
Any working suggestions?
