Fitted both cameras this morning, a little fiddly but once you do one the other was easy, hid all wires behind headlining and down the door seal's then under dash trim, setting up the E-prance was easy enough and so far both working as they should..this is a shot of the E-Prance in my Jazz.
You could hide the camera higher up behind the mirror if you wished to be more stealthy. The only part of the power wire you can see is that behind the rear view mirror.
