I picked up a LG HBM710 Headset that I cannot get to link with my 680. I have a Logitech that works fine. I can program the Treo to ID on the Add Device screen. It recognizes it and adds it to the list, but never actually links to use it. I bought it refurbished on Woot, but before I Call it in under warranty, I'd like to see if anyone here has any tips. Thanks.
