Ok, as I believe this is the definitive answer, I thought I'd post this here so people can find it easily:
"The Discover Navigation Pro system includes additional equipment such as natural voice control, media and streaming services direct to the car, gesture control, and dual map display on the infotainment and digital cockpit pro"
Media and streaming is definitely a basic nav function - I've seen it.
Gesture control - yes, like my current Mk7.5 NavPro gesture control - utterly f***ing worthless crap. I turned it off in days of having it because it makes the music skip all over.
Voice control - the basic nav has it for the Stereo and the Nav inputs, Navpro seems to add more so you can control the aircon with it, maybe some more things?? If such a thing is what you want?
Dual Map - ok, so this is the same as with the Mk7.5. That does suggest that like with the Mk7.5 you CAN get the map on the AID...somehow. Although to be fair, I was going to order the HUD, which makes that probably worthless anyway as the main purpose of having the map on the AID is to give the driver some in-view sat nav directions. HUD is 600 quid. NavPro is 1600.
I *suspect* there probably is more to it than this in that the interface has some different options and the whole unit is a little more responsive being a higher powered processor.
And just another thing "Digital Cockpit Pro" is standard on ALL UK Golfs - this refers to the screen behind the steering wheel where the clocks are (known as AID). Also, NavPro does not make the entertainment screen bigger like it did on the Mk7/7.5. Don't order it imagining you are going to get any visible uplift. It also doesn't improve the audio quality - you need the Harmon Kardon option for better audio, not NavPro.
Anyway, wanted this topic to be definitive for others.
