Hi, I'm looking to be able to trigger the voice command input using my bluetooth stereo in my car. I have access to phonebook dialling, play/pause/stop/next track/previous track. I think it would be easiest to have a phonebook entry that I can dial, it would put my stereo in the mood for activating the microphone, but this mood is invoked anyway when I manually start a voice command using the home button.

I've tried looking for a cydia app that does something similar to this, but don't really know which keywords to optimise my search. Does anyone know of something existing that can do this? If not is anyone interested in making it?

Thanks in advance for your help.
Mike
