Having had previous Tom Tom's and for someone who travels over 40,000 miles a year this is a must. The reason I went for this is the Live element of the unit. Not only will it advise of traffic hold ups in real time, the main reason I wanted to upgrade was for the speed camera info. Although I had the speed camera info on my old 530 Tom Tom, this unit will alert you to mobile camera's which the old one couldnt. The unit will have paid for itself if it alerts me to one of those hidden mobile camera's on the road side! Plenty of other useful info on this unit, too numerous to mention but definately one to go for if you are on the road most days of the week.
