Yeah well I have an older Sena SMH-5-FM which is BT 3.0 or 3.1 and before I go and spend $300 on a new headset I'll get all of the free updates I can. BT is supposed to be 100% backwards compatible between versions... Something is not communicating correctly. First start of the day everything syncs up fine but when I stop for fuel or lunch when I restart the bike the headset tells me the "Phone is connected" and "Device is connected" (Nav6) but the TFT does not connect to the Sena. Sometimes I will turn the Sena of and on and it will connect, other times after repeated power cycles of the Sena suddenly 5-15 miles down the road the helmet icon on the TFT turns on and music starts. Meantime before this happens the BT icon on the TFT is flashing as if it is looking for the lost connection but if I pull over to see what is going on and go to "Connections" menu on the TFT it shows no riders helmet device available.
