I just got a good deal on a low mileage 16 A3 Quattro premium. Coming from a 16 gti. Just thought of it as an AWD version. Anyway, I assumed that when I hit the Nav button it would come up on screen. Little did I know, it’s not an installed option. I called the dealer and they said it’s not something that they can just add. What hard parts do I need or is it a complete waste of $$$. Also not having CarPlay is a pain. I’d be fine with just that, as it was great in the GTI. I’ve seen kits to add it, but does it work properly not having a touch screen? Any help would be greatly appreciated. Thx
