If you do, please keep me posted. I've never programmed in my life (unless you count what goes on in this thread. Anyway, I really don't even need the buttons, or so I think. I really just want the music controls while I'm in the GPS window. Mainly, I use the spedo in iG to test how accurate my dash one is. But I've heard something about changing the temp readings to GPS speed readings, but that's something else to look into.
