Follow-up question from a Jan 24 2012, comment from a Sena Rep about plans/solutions for possible updates being done by Bluetooth. I have an older model dual set (1+ yrs old) that is not capable of firmware updates at all. I have the coaxial connector not the usb type. Not even sure the firmware update would do anything anyway. My units work just fine for me but, if it improves the functionality I'll update it. Any current information would be great on the possibility of updates with bluetooth.
