Thank you Sir.
This worked for me. This morning my Bluetooth, while I was streaming music, randomly just stopped, and then the Bluetooth was literally inoperable. Have been using the system for about 2 years with no problems and randomly the Bluetooth part of it just stopped working. Same symptoms as others, options greyed out, firmware showing '------', etc.
I have already done the application update manually before, so didn't bother with that but the Bluetooth firmware files you posted were perfect. I did the first update initially, and the Bluetooth actually started working at this
