It's not exactly intuitive. I added my myAudi details to Google maps, and sent a few destinations from there. You can verify they have sent by logging into myAudi on your PC and checking they appear as saved destinations under "Destination entry via myAudi". In the car it shows them under "myAudi contacts" in Navigation, but you can also get to them from Special Destinations in Audi Connect. You might need to "refresh" and choose the online option. As said, not exactly intuitive!
