...and it never will (at least for iOS):
Keep up-to-date and travel faster with AVICSYNC (Android). Use the new app to further expand your mapping data, access online location-based services and plan your trips, both inside the car and out! AVICSYNC will automatically sync the data from your smartphone to your navigation unit when you're back in the car.
The AVICSYNC smartphone app will be available soon.
