thanks for the help. i finally got the phone to sync. i didn't realize that the 770 has to start the bluetooth connection. so i paired the two as usual & then hit the pair button. the sync then asked for the passkey & i was in business!! by the way since i've been using this samsung sync i haven't had to re-pair the two yet. my old sprint samsung blade i had pair them together almost every time i wanted to use them. thanks again those posts were very helpful. derrick
