As Dan, I also used K6BT with 302 and xcsoar running on dell streak, and later upgraded to CNv successfully. It worked flawlessly, more reliably than my car Bluetooth.
Now I am using LX9000 and V80 in my new glider so have no use for it and can be talked into selling it.
And while we at it, I also have a 302 I may consider selling.
