Most, if not all, bluetooth headsets can be used this way with a PC.
Can a blue tooth head set designed for a cell phone be used for a PC. I think this would be a great tool for voice control as well as navigation. Many times my wife or I like to listen to just the plain radio but need the navigation as well. The voice prompts on the navigation are very helpfull and currently I use a PC head set (ear mount) but am teathered by the cord. Would be great to have some type of wireless headset.
