umm, well, for starters your bluetooth headset has to be set to scan mode, normally you gotta hold the button on the headset for about 4 seconds and the light on the headset should alight and stay alight. If this happens then that means its set to scan mode and ready to be detected by another bluetooth device. You seemed to be on the right track with everything else, yes you do have to go to accessory settings and then to 'register bluetooth device'
