Hi! Hope that you don't mind if I keep my modification log over here.
In MQB cars (which includes Golf MK7) there's couple options where it comes to rear-view cameras:
RVC-Low: simple camera, triggered by reverse light bulb signal.
RVC-High: camera module connected to CAN-BUS, with 4 view modes.
AreaView: set of 4 cameras with stitched 360 degrees view around the vehicle.
Recently I retrofitted RVC-High but having front camera would be a cool option. AreaView retrofit is complicated and, what's most important, expensive. So I decided to add an aftermarket front camera and force the system to switch to it when needed. Having RVC-High opens up some possibilities. The most important thing is that the video feed from the camera is still available after shifting from reverse gear. Also it's possible to bring up the image on the display by pressing parktronic button. Thanks to that it should be possible to switch from rear camera feed to front camera feed when needed.
Still waiting for the camera to arrive, but this is the one that I chose: CCD Front View Camera. Also considered this option: YIFOUM HD CCD Car Front View Parking Night Vision with an easier installation in front grill.
Anyway, I decided to have this video feed switching both automated and manually triggered with a button. Below there's a quick diagram that I prepared for the control module (don't mind the LED polarization which is wrong here). I want to use something like ATTINY88 micro development board as a control unit for my setup.
Planning to use I/O as below:

Planning to use I/O as below:
- Input 1: reverse gear status (from backup-light or R indicator in DSG trim)
- Input 2: parktronic status (from orange indicator on the parktronic button)
- Input 3: button to manually control video switching if needed
- Output 1: video switching relay control
- Output 2: front view indicator (more about that later)
- Output 3: parktronic button override (also more about that later on)
