Gregg, the silver button is the illuminated hazard switch, dim when off, flashes bright when on
Craig, yes the key position is fine. Hidden behind the dash panel is also the steering lock key barrel, which is just for the steering lock.
Guye, the button for track select and volume for the bluetooth streaming audio is also going on there, just waiting for the kit to be delivered. No, I'm not joking. The mic will go wherever makes sense, probably somewhere near the left knee position, but I'm not really fussed about mic, the kit is more for streaming audio from my phone. I am not having a head-unit radio, just the blutooth streaming to a stand-alone amp powering the speakers.
