I have own the garmin c530 for about a year now , and i have to say its quite nice and perform well . I use it nearly everyday as i drive for a living , it never get I lose no matter how many wrong turn i make . it have a vast amount of point of interest store in it allready with the ability to add more . it have a excellent battery life , and be also quite durable . i wil say though on the other hand its be bad when i tcomes to pick the best route . I can be on the interstate and it may want to send I down a small highway that would take 20 minute longer than just stay on the freeway . also drive time be quite accurate also . people complain that they be `` optimistic '' which its suppose to be as the gp beleive or not doesnt know how many redlight u will hit . also u can program red light camera into it so it will alert when ur comee up on one .
