"Since I first got the car, the Apple play connects sometimes and doesnt connect other times. I have to reboot the system as if it is the first time I am pairing the CarPlay to the Hyundai. Then it may work for a week or two, and then I have to pair it again. Dealer said that Hyundai is more favorable to android systems! Other than that problem, the car is great"
