Interesting bit:
if you are using carplay, with lets say google maps or A better route planner thats not sending the directions to the dash, you can use the VW navigation to show it. while having live route guidance through ABRP on screen. This is not possible with AA because every routeplanner works on AA with giving direction info.
interesting bit #2: you can run multiple navigation on AA and carplay through the different apps. With Carplay only Apple Maps will show the directions on the dash so Apple maps can be in the background while also navigating with lets say Gmaps on the carplay screen.
This doesnt work with AA, because the navi directions is being send by the active navigation on screen. Only when you switch from application it switches too
