The infotainment system from GMC features just about every feature on the market and an intuitive user interface. Users won’t have to focus on a tiny icon while the car is moving thanks to the huge, easy-to-read visuals and generous touch zones on the 8.0-inch touchscreen with navigation that we tested. It is just as simple to use as many smartphones, and it responded to our inputs fast. There are enough outlets and USB ports inside to power a large number of smartphones.
