The system works exactly as it did when I installed it. About the same time I installed a similar system in my S, but changed out the stereo to get a bigger display (the S radio has a much smaller display than the SV). I also seemed to have more static on my S installation than my wife's SV, so I took out the transmitter on my S and hardwired the camera to the radio. I've also done more work on my S (added backup ultrasonic distance system and ultrasonic blind spot monitoring) so am more comfortable with running wires from the back to the front of the car. I have found that in rainy weather that the camera lens sometimes gets a water drop on it, distorting the image a lot. I still wouldn't do it differently than the writeup, but if you live where it rains a lot, and you don't mind all the hatch trim work, you might install the camera higher up, perhaps under the hatch handle. The image is a little cleaner with the hard wiring on my S than the transmitter images on my wife's SV. I might run wires rather than use the transmitter solution if I had it to do over again.
Could you please confirm the pin positions on the back of the radio? As mine is missing some, I'll need to get some new pins and install new wires into the connector. I've attached the connector diagram (Large top right connector).
From what I understand from your photos:
Pin 21 (shield) (Top left of connector)
Pin 41 (video) (Bottom left of connector)
Pin 45 (reverse sense that should be grounded) (5th pin from the left on the bottom row).
