I have a new Plantronics 975 bluetooth headset, and a new N900, and they will not talk to each other over blue tooth. The headset works fine with my former phone (an LG Shine), and the N900 will also talk to the LG Shine, so I know they are both capable of bluetooth communication. why are they not seeing each other? Is this a known issue? Is this something that can be fixed with a software patch?
