Apologies, might have confused things talking about POI.
In the Mk7/7.5 golf you could add the speed camera database as POI using the SD slot.
What Fred was confirming is that it is not possible (in any way) to add speed cameras to the sat nav systems in the mk8 golfs.
In case you’re not aware, one option is to use a 3rd party map/navigation systems using Apple CarPlay or android auto. One good system is called Waze and is free to install the app on your phone and use. Waze has good live reporting of fixed/mobile cameras and accidents, if you’ve got an iPhone, the inbuilt Apple maps now has fixed speed cameras too and I believe Google maps will follow suit soon.
