Although the Clarkson voice commands are the main feature, there are a couple more Top Gear additions. You get five custom car icons inspired by some of the memorable "challenges" from the TV show, including the airship James May famously flew across an active airfield "by accident". There's also a special Top Gear points of interest category, which almost exclusively consists of popular tracks such as Bedford Aerodrome's GT circuit and Santa Pod, plus Top Gear's own circuit. These will be useful if you're a fully paid up petrolhead who likes to randomly visit the odd track on the way home.
Beyond the Top Gear topping, this is a 4.3in widescreen device, rather than the 5in format which is becoming increasingly popular. It also sports an integrated mount, rather than the clever magnetic system now used by TomTom's top models, or even the one-gesture system found in previous premium ranges. Instead, the mount is permanently attached to the device, and simply folds in when not in use. This makes the Top Gear Edition easier to use with and transport between multiple cars. But it also makes screen attachement a little more fiddly, although if you don't like leaving your mount in your car for security reasons there's not much difference. The car power cable now also doubles as the USB cable for installing software updates, although this now appears to be standard across TomTom's range.
So the Top Gear Edition's physical attributes are decidly value-oriented. But some of its capabilities are much more high-end. In particular, this is a TomTom LIVE device. So it comes with a selection of mobile data-enabled services, and a year's subscription provided out of the box, after which you will have to pay £47.50 a year to maintain the connection. Although TomTom's LIVE services, despite being the first on the market, have now been surpassed by the competition in terms of broadness of features, they still have arguably the most important key feature of all - HD Traffic.
