My inexpensive BT handsfree headset allows me to use the Razr's V3c voice recognition in the phone. I just press a button and the Razr's voice system is activated. How can I get my 2007 Prius is act the same way? I do not want to transfer my numbers to the car and add voice tags when the phone already has an excellent voice dialing which needs no training. Does anyone know if this is possible? Strange that a $25 BT headset can do it, but a hi tech car system can't.
