I downloaded a program called Voice Dialer HF. I put a shortcut to the voice dial on my home screen. I put a short cut to enable BT on the home screen.Does this mean I have to buy a BlueAnt? I just bought a Jawbone2. That is a Blueant Q1? I wonder where you can get that?
When I don my headset, I turn on the BT with ONE stroke (Beautiful Widget BT).
I mount the droid on my dash and plug in the charger (so my screen stays lit).
When I need to make a call, I press the Microphone button (already set default to Voice Dialer HF) and then it speaks to me just like on my old phone did and just like you mentioned before. It even asks me Home, Mobile, Work etc. The moment I say YES, it places the call and switches to my Headset. The microphone on the Droid is sensitive enough that it can pick up what I'm saying without trouble. The only trouble I DO HAVE is when the kids are arguing or the radio is on. Then it can not discern me from the background noise.
So I can't tap the headset button to activate the microphone (on the phone or head set), but its still a single keystroke to Activate & End the call.
I wish it was like my old phone, but it's a small adjustment for having a droid.
