I've got one - it sits in a drawer in the office - . TomTom no longer support these old models. Don't bother is my advice. Buy a recent model with free updates for life.

There are plenty of people on the internet who will sell you a map update which will possibly compromise your machine. The upgrade won't be authentic and will have to bypass something to install itself.

It's probably cheaper in the long run to get a modern machine with lifetime updates, which TomTom has had to offer to keep competitive. Either that or use a mobile phone.
