I have tried that as well as turning the bike off, diconnecting the phone, restarting the music and changing the input on the bike. Sometimes one of these things works and sometimes none of them work! This is why I refer to the problem as a ghost, it is elusive and I can not duplicate the cause or the cure. I have even gotten the error message while it was playing fine. Other times it stops playing the music , but shows no problem messeage.
Of course this is not a big deal around home where I can get several good fm stations, but I would like to get it figured out before our trip next month. Other than this problem the f6b is fantastic!
