“Panasonic KX-TG7641 Bluebooth to latest generation cell phones failed We have KX-TG7641 which successfully paired with cell phone 2+ years ago. Recently, we got two new cell phones (T-Mobile LG Optimus F3Q and Samsung S5) and neither will pair correctly with the landline Panasonic phone. They detect the Panasonic base during scan routine but the Panasonic base/phone never leaves the Registering cycle. Both phone paired with automobile Nav systems without issue to get and send calls so we know the general routine and the cell phones are not faulty.”
