My wife's Edge had the same problem. Bluetooth phones that had been working fine for 2 months stopped working, and you couldn't pair new phones. Took it to the dealer and they applied the latest software update. Everything's back to normal now. Phones pair again (and you can pair new phones without trouble). I don't know if there was any specific fix for this in the latest update, but if nothing else it seems to have rectified the problem. The dealer didn't swap out any hardware in this case.
Good luck with yours. I'm hoping this fix is real, and not just a reset that masks the underlying problem for another month or two...
