Thanks for all the replies.
I just took the Niro to Mt. Mitchell in western NC for camping and the GPS worked great.
Some GPS quirks I discovered:
- Our leader gave us all GPS coordinates as well as addresses to the destination. The GPS coordinates worked fine, however when I tried to save the GPS coordinates I couldn't pick a title for the shortcut. The title of the shortcut was the GPS coordinates itself which isn't very useful. I couldn't name the shortcut something like "Pisgah Campground". It would be nice to name the GPS coordinates especially since we used like 3+ coordinates for the entire trip.
- Inputting GPS coordinates is fine, but not very fast. The "-" and number keys are on different keyboards.
- I think the biggest advantage the iPhone has over the car GPS is the ability to input a destination while the car is moving. Sometimes decisions are made on the fly and the car GPS is useless if you need to change destinations while on the road.
- I used my iPhone navigation just for testing and sometimes the car's audio would lower the volume of both the music and Siri's voice. So I couldn't rely on audio cues, I had to just look at my screen.
- One thing I love with the car GPS is that directions can be visualized on the center screen behind the steering wheel. I wish Apple Carplay could transmit it's directions there.
- For the car GPS, I switched the color of the icon representing the Niro to red (since that is the car's color). I'm surprised KIA didn't put the color of all their cars in the settings.
