Navigation issue

Overall performance is very good . Value for buying turbo engine. Very good pick up. But I am not satisfy with the Navigation system. Need to start the navigation in the Mobile . Then connect to System using Android Auto App via Bluetooth. Can not set the target directly from the System. If we want to change the target , then disconnect the mobile from the system first . Then again set the new target in the mobile and start navigation. Then connect to system by enabling the blue tooth. It is a tedious process. Better to use the system only for music. And carry a Mobile for Map.
