All the information comes from the brain / infotainment . If the brain has Navigation, the maps will work whether APP or NAV. The screen only reproduces information from the brain. It works same as a computer, if you have "windowns" installed in the brain of your computer, you will see windowns in the display... something like thatI just read that the APP function does not work with 2016 models, is this for both with and without Factory NAV? I'm looking at this upgrade for a 2016 Golf R w/NAV, but I would need the app function to work.
thank you for your time
