You have a phone that can do GPS and navigation, and probably do it better than the software in your car. The phone is much more easily replaced than the built-in navigation unit, should it stop working for any reason. The phone works the same way in all cars. The phone gets software updates easily and seamlessly.
Quit putting unecessary technology in cars. It will only cause expensive problems in 5 or 10 years, because it will be utterly obsolete by then and unfixable.
The car should not care what the date is. It should not care what time it is. The clock in my car says 12:00. Why? Because I have never bothered to set it. I don't care, and I have the correct time, accurate to the millisecond, on my phone.
The technology in the car should only be about running the engine and transmission and other essential systems in the car.
