Hello everybody, I am here as I need an advice regarding the purchase of my first ever GPS navigator. I was looking at TomTom website and I am interested in TomTom Go 520, but please, I have some question : - once bought it, maps download and all other features like traffic updates, will be always for free? - - should I pay a subscription like an annual one? - - - what is the main difference between the 520 and 5200 model ? - - - - what is the main difference between Go520 / Start and Via ? I hope to receive your answer ! Have a nice day all !
