I do so much research before buy this product and see a couple of negative review , but I think they must have just have a defective product because mine be wonderful . it be the first navigation system I have ever own and would definitely buy from Mio again . the feature be great , the wide selection of map color option be great , and the volume be appropriate . my only disappointed moment be when I realize that I would have to buy a separate memory card to save MY POI and stuff . but since I get such a great deal on it -lrb- $ 175 -rrb- , I can still afford to buy a memory card !
