I don't have a sure fix, but do have some insight. Some systems just don't pair with some phones. It sux but it's just the way it is. Now, upon pairing, make sure the phone stays "awake" during the whole pairing process. I also know that some (most) blackberry phones are not very compatible to some Bluetooth systems. My iPhone paired to my gs300 but won't load the phone book. I figure that's just the way it is. Good luck!
