When I bought my TomTom, I had a guarantee of lifetime map subscriptions. About a year ago, I had to contact the company because I hadn't received an updated map for over a year. They answered my email and assured me I would receive one, and that I needed to use an upgraded memory card. I purchased this card, installed it, and downloaded my map. Since that 1st map was sent, I have received no more updates. I have now contacted the company three times, and they are evidently ignoring me, as I have received no replies. User's recommendation: I liked the format that TomTom uses, but if they can't keep their promises, I'd advise against purchasing their devises!
