Thanks. I'm glad someone appreciate my efforts to spread the word on these DIYs.

The mere fact that the ECU has the "capacity" to recognize that there is an MK4 Navigation in the car sort of suggests that coding is pertinent to the function of the entire navigation retrofit as a whole.

Since I coded my Nav I have had no issues. In fact the Navigation is perfect and better than all the Tom Tom Go devices I've had in the car in terms of start up and location recognition time. It is a fact that the MK4 uses the car's ABS and/or wheel speed sensors to determine precise location of where the car is relative to the map.
