How do I get my CU920 to download address book info to my Bluetooth Blue Ant ST3? I've tried every way listed in the Blue Ant User Manual, but they don't seem to work. The only option on my phone which seems to cover "sending" contact info at all is the "Send vCard via Bluetooth" option, but when I select this, all I get is a "Bluetooth Busy" message.

You do not have to record voice tags for your contacts. Go to Tools, click on Voice Command then Settings and finally Train. Follow the prompts and once complete, your phone will them be able to recognize your commands. when you hit the call button on your bluetooth headset, the phone will say "Say a command". at that point you can tell it to call any contact in your list or tell the phone to call a number (i.e. call 601 555 0123). The phone will ask for conformation and then make the call. The phone will also respond to request to check missed calls, check voice mail and tell you the time and date. Hope this helps.

1. If the Supertooth 3 is on, turn it off by holding down the green Multi-Function button for about 5 seconds (until you hear a voice announce "BlueAnt ST3 powering down").
2. Hold down "Vol +" and the green Multi-Function button until you hear a loud siren/distinctive tone.
3. The Supertooth 3 will turn on. Hold down the green Multi-Function button for about 5 seconds to turn it off again.
4. The Supertooth 3 has now been reset: all pairing and other information has been deleted. When you turn the Supertooth 3 back on again it will prompt you to select a language and then go into pairing mode.
