We just updated our dual Sena SMH10's to 5.1.1.  Unpaired phones, as recommended, and repaired with no problems.  However, we are experiencing three problems.  (1) Unit 1 is now very choppy when playing music through iPhone.  And (2) Unit 2 cannot initiate intercom by either tapping the jog dial or VOX ("intercom not connected" message).  Unit 1 is the only one able to initiate intercom to Unit 2, in which case it works (so I know they are paired), but neither will shut off intercom automatically, even after moments of silence.  Both units are still under warranty.  Please advise.  Thanks!
