Tried this, didn't seem to work...

Today I went out and grounded the light green parking brake wire and did the firmware edit, worked like a charm. Thanks alot... Now if I can only change the size and color of clock... And why it seems to say kph on the speed, even when the setting say mph...

^^^ Alright, looks like I have enough info to do it myself if the shop won't do it on Friday! Thanks!

Sweet Jesus No! Ground the parking brake wire to the black ground wire; basically tie the two wires together by solder or automotive splice connectors. Take the other end of the parking brake (the end going to the parking brake switch) and coil it up neatly out of the way, wrap electrical tape on the end so it doesn't ever accidentally make contact with anything. Beating a dead horse here, but... From where do I pull the light green ground wire from?

Well, with everyone ranting and raving about how good this knob is I guess I will have to get one. But I would really like a black one... Any timeline on when that will be possible?

Alright, I read all the posts but I did learn alot. I am capable of pulling off the software side of this, but the hardware I am not sure. Just bought a 09 Malibu for my wife with the F700BT installed. Problem is that I can only access the functions we are all after with the parking brake applied. Does that mean that the parking wire (which I am told is light green) is not grounded? What is it connected to right now then? Do I need to just clip the wire and ground it to the power harness? Or should I just get the shop that installed it to ground the parking wire, with some story about
