Anyone familiar with the Tomtom one GPS?

I intend to buy one of these for my boyfriend for Christmas, but I know nothing about it. I am considering bidding on a factory sealed one off of eBay. If I buy a factory sealed one, would I need to purchase any other accessories to go with it?

There are three versions of the TomTom One. The latest contains some map, software, and processor improvements not available on the first two iterations. The only disadvantage of the newest version is that it lacks a removable SD memory card. I recommend the Version 3 unit: http://www.a2dvoices.com/realitycheck/gps/TomTomGPS.html
