Apple Maps works perfectly fine and looks far better than Google Maps. The comparisons I've done, it gives much better, more clear instructions too.
To give more information on what I mean, here is one example. As I'm pulling up near this intersection, Google will tell me to "Take a right at the light", which is NOT accurate for the route I'm going. However, Apple will say, "Go through the light, and then a slight right", which IS correct.
