Sorry to keep adding information, but since it is going to be new for you, here are some other neat features:
As I said, Siri will now be available to you in the car and can answer questions and help you. For example you can ask for local weather info, location of restaurants, stores, etc. Very helpful if you are traveling or in a different part of your home town.
This is all hands free, Siri responds to your voice. If you like, you can pull over and interact with Siri which feels safer sometimes.
When you get into your car, you press a button on your steering wheel to ask Siri questions. You just press the button and say "Directions to (Fill in the blank.)" Siri pops up the location and you hit a button and the directions are there for you.
A magic thing is that if you go to the same place, same time every day or a couple of times a week, when you get into your car it will automatically set the nav to that location. So it anticipates regular driving activity.
The Nav map and directions are really good. I have had a Garmin and various map apps and I think the Apple nav is the best.
The visual screen view is very concise and helpful. If you tap your screen on the top you will get vocal directions which are excellent. For example, they don't just say "turn right", they will say go through the light then turn right. Or turn left from the middle lane.
They also let you know what the next couple of moves will be. That you will turn right then turn left.
So the directions are very clear and helpful. This is especially important if you are out of town traveling and the area is a complicated interstate situation.
When you bought your new car, you paid for this system so you might as well use it and enjoy it! The technology is amazing.
