after a lot of research I settle on the c530 for the price . I be terrible with direction , and get lose a lot so this be begin to be a necessary purchase . this gp be great ! the screen be easy to see , and the auto-adjust mode be really helpful . this gp have a amazingly long battery life - mine have be go strong for over 5 hour . I have not try update the map , and since I buy a refurbish unit some map be outdate , but in general I have not have any trouble with it . I honestly can not say anything negative about the c530 . for what I pay I have be extremely pleased .
