Can Nav-only head unit display video via Lockpick?

[flwildcat]

Here's my question - I have an 07 LTZ with the navigation head unit but no rear seat entertainment. I'm looking at installing aftermarket rear seat entertainment (probably headrests) but I want to know if the head unit will be able to display the video from the aftermarket entertainment using the GMLockpick? Also, will the lockpick enable audio to be wired direct through the speakers w/o using an FM modulator?

Can anyone verify one way or the other?

Thanks, David. That slipped right by me. Now just one question left - can the audio be wired through the factory stereo or does it have to be done via an FM modulator. Does anyone know for sure?
