I used to love this app and I always used it over iPhone maps, because it is more user friendly than iphone maps. It gives directions ahead of time, not last minute. And easily allows you to look ahead to the directions coming up. However, lately it more often than not takes me to the wrong location! And I do not just mean that it gets me close but is unsure of exact location. It literally send me the wrong way nowhere near where I am trying to go. For example, most recently It told me to turn left off the freeway to arrive at a business in Stockton when in fact I was 3/4 mile away from the building and needed to take a right off the freeway to get there. It has done that a few times when I have attempted to use the navigation to arrive at well established businesses that should have been easy to find. I am now forced to use iPhone maps, because I would rather have last minute directions and a more confusing screen than drive in circles without finding the location.
