Hi. I cannot get voice dialing to work on my new gn3. I have voice control & hands-free mode on. When I press the call button on my blue tooth my screen lights up. If I open the cover a message tells me to 'tap the screen' to call; when I speak, nothing happens. I was using an older Motorola H720 blue tooth so I bought a new Jabra Wave and set it up- the same result. It seems the only way I can make a voice call is to open the cover and tap the screen, which makes no sense. With my old RAZR I just pressed the blue tooth call button and spoke my command. What am I doing wrong?
