Two & a half years ago I bought a TomTom 5200, which came with lifetime maps, speed cameras, & live traffic. My previous TomTom wanted about £60 a year for map updates, & a further £30 for speed camera updates. Two & a half years on I have been very pleased with the 5200. I am going to America later in the year so started to think about a sat nav. Much to my surprise you can download for free any other map in the world. You just need a micro sd card to increase the memory capacity. I hope this may be of use to any other world travellers.
