Trigger Cortana via Bluetooth

[noiprocs]

Hey guys,

I don't have a hands-free kit in my car so I was wondering whether I could use a Bluetooth device to activate Cortana. I have a bracket mounted on my front window and I would like to have a Bluetooth device that has a single button that can trigger Cortana. I could then interact via Lumia microphone and speakers. Do you know any solution to that?

I've been able to trigger Cortana using my BT headset by pressing the call button, in the same way that this triggered the TellMe voice guide on WP8. However, unlike WP8, when I do this it unlocks my phone to bring up the Cortana screen, which is not particularly helpful when the phone is in my pocket! I'm hoping I've missed a setting somewhere which will allow the Cortant voice recognition to accept questions and read answers underneath the lockscreen.
