The pics will need to wait till early august at best, cuz that's when I get the second exhaust pipe installed...
Now as far as the Nav system, there is no way that if you cut the "move sensor" signal wire, your nav system could black out when moving the car. You MUST have cut the wrong one. Check again. I have upgraded to the latest version (2009) and I can phone and change nav instructions while on the move. Look, it's not an esoteric science ...If the system does not detect the car is moving, it will simply act as if you were parked. So now cut the damn right wire... ;-))
