When you go to turn it off it will tell you what all other features it turns off as well. I personally hate it, I don't think its ever recommended correctly. In fact the majority of the time it recommends places that I've never even been to, or even been remotely around. However I liked some of the other options tied to it, so I've left it on.
Another annoyance is the fact it will notify when I have the car in reverse. When the cameras are on it won't show anything else on screen. So I'll hear the alert, then I'll hear a warning about 6 minutes of traffic but have NO idea what address it put in for me.
I like the idea of it, but like a lot of the software, it was implemented very poorly.
