I love mine, would not leave with out it . every one needs to have one.The only thing I do not like is that it comes with only one dash mount , and I need to because I have to cars I use. I also leave it out in the cold and it dose not do ant dameges to it. I love how you can change the voice from a man's to a woman's. Some times I speed not paying  attenion to what I was doing and because it sit's up higher on the dash I can see it better. I love how it show's you that you can take different ways, or if you miss you'r turn it all ways take you to the next place to turn.
