I have discovered that the lifetime guarantee for maps isn't what it seems. One supposed that the lifetime was the lifetimne of the machine, or its owner. However it now seems that the Lifetime is that which TomTom choose to have for providing updates. Which is to say, there is no lifetime guarantee, only a service so long as TomTom choos to provide it. Those with perfectly servicable GPS units and who have purchased a pack of maps as a sepparate purchase now find that their machine has been declared obsolete and that their lifetime guarntee on theoir map package isnt!
