I know that you can hack the GPS feature of the OnStar units, but has anyone thought about integrating the OnStar mic into the CarPC for voice control? (Program execution, playlists, etc.)

I just did this on m 2002 Silverado a few weeks ago. I made a cable out of some cat5, soldered on a 3.5mm plug. I soldered the other end at the microphone, disconnecting it's plug from the vehicle. Works great with RRVoiceControl. Don't have a compatible cell phone to test that aspect with.
