If I initiate or receive a phone call while listening to the radio, my Sena 10, custom built for Schubert C4, must be turned back on by rider input. I have tried to wait for quite some time, but have failed to experience that the radio comes back on on it's own.
One more peculiar thing is: When I turn the radio on following a BT connection, the Radio comes on at such a low volume that I hear nothing before I touch the volume adjust button. After I blip the volume adjustment, the volume returns to the setting prior to what it was prior to the BT connection.
I never had this issue prior to the latest hardware update.
