With your phone closed press and hold the center button on the bluetooth until it starts blinking blue and red the open your phone and go to blue tooth> ad new device> then it will go to pairing then auto pairing and that should do it

I wrote to the company. They told me to charge the unit for 8 hours. take the battery out of my phone, leave it out for a minute or two , put it back in and sync again. it worked.
