Well, if you use Android auto or apple something, you get the same benefits as the built in nav. However I like to use the built in nav because it shows in the HUD. Also I like to take care of my phone battery which means I hate it that it always charges when you plug it into the car. That means that it will charge to 100% (and the USB is high powered so it charges fast) and then keeps it at 100%. It's definitely bad for the phone and it heats up a lot as well.
