I hope someone else is able to answer your question, but personally (and I've read and experienced quite a bit on all things Audi) I am not aware of the possibility of any of the things you asked for. Not saving scale, not opening directly to map.I like the NAV map set to a certain scale, but every time I start the car the map has reset to a larger scale than I like. How do I get it to remember the way it was? Can it be set as an option somewhere? Can I set the NAV to open directly to the map?
