However, ALL car navigation systems are idiotic, because they're all 5 years behind the times by the time they make it to market; smartphone navigation apps are far more advanced, and always will be. It's even more idiotic that the carmakers actually expect people to pay for map updates, instead of just updating the maps continuously for free like Google Maps
My Audi has Google Maps for it's navigation system already, it works great.
