Thanks for all the info, guys. I spent a good bit of time playing with this over the Holiday weekend. I have an old Motorola H500 and MotoROKR S305 hooked up to my E4GT and my wife has a new LG HBS-700 hooked up to her E4GT and after lots of playing with settings, resyncing, etc. I have only ever gotten Voice Talk to work with the phone locked under one scenario:
1) Open Voice Talk manually
2) Hold the call button to do a redial
3) After the call is ended, let the phone lock automatically
4) Pressing the button now will wake the phone and launch Voice Talk. However, after this, I'm back in the "stuck" state where pressing the button does nothing.
Sometimes, on my wife's phone with her LG bluetooth headset, pressing the button with the phone locked sort of launches Voice Talk. The nice lady will tell me how many missed calls I have, but she doesn't continue on to ask me what I'd like to do and attempting to give a command or say "Hi Galaxy" does nothing. If I then unlock the phone, Voice Talk is the open app, but it's just sitting there at the main screen.
I was considering buying a new bluetooth headset since several of you seem to have this working, but after trying with the ones we have, I'm worried it still won't work and I don't want to waste the money.
Could one of you who has this working confirm that pressing your BT button with the phone locked does in fact wake the phone up and launch voice talk, that you can then verbally make a call or send a text and then after that first one, do it again? Also, how exactly do you go about connecting your BT and launching voice talk? Do you have it auto-launch on bluetooth? Do you have your phone locked or unlocked when you connect the headset, etc.?
I just don't understand why I can't get this working. I've spent a ton of time and tried so many settings combinations. You wouldn't think it would be this hard...
Thanks again for all your help.
