They lie. I bought a tomtom with lifetime maps. and now they send me a email that my gps no longer will be supported with new maps supposedly because my gps is to old for the new maps. So How can they sell you a gps with lifetime maps and then say they don't supporrt new maps after 5 years.
Because they want to sell you another gps! I will never buy another tomtom again because of this lie! Sure they will give you a hell of a deal for a newer model. save ya about 20 bucks. What a Joke!!
