TomTom are admittedly hot on their licensing, but I've never had a serious problem with them- 1st activation is automatic, 2nd can be done via TTCode on the spot; It's only the 3rd activation and beyond that can cause trouble, but as long as you can supply a copy of a purchase invoice they will accept it. Any more than that and you'd be better buying an updated map anyway!

iGO2006 use yet another licensing model: the maps/software are tied to the supplied MiniSD card, which can then be used in any device at any time (as long as it has a mini or standard SD slot of course!). Can be a bit of a problem if you need to run other programs at the same time, and they are not in main memory, but perfect on the Ameo which can just have the iGO card in the slot, and everything else on the MicroDrive!
