Most cell phones have to be set for always visible for the computer to find it. Also, some phones are only set up to search. If yours will allow itself to be found, make sure it is. Always start your phone first, then the computer. If you still cant get it to connect, remember that the nextel phone are different operating system because of the direct connect software. And last but not lease, uninstall the bluetooth addapter from vista and reinstall. restart the computer and try again.
