Summary: Okay, so I've only gotten to use it a couple of times when I really didn't know where I was going, but it definitely did a great job those two times! It lets you know far enough in advance if you're going to need to change lanes, make an exit, etc. Very easy to use - my cell phone sometimes confuses me, but this was a breeze. I use the windshield mount, and it's very easy to read while driving. This is one purchase that I'm very glad I made.
