Free Tom Tom Go

When we heard that TomTom was updating its range with yet more enhanced navigation technology, we couldn't wait to get our hands on one of its new satnavs to test it all out. The 930T we have here is the top-end model, featuring both the new IQRoutes functionality and Advanced Lane Guidance.

Both features are designed to increase the efficiency and clarity of navigation, and of course you'll find all the usual features and extras that have made the satnav giant such a household name.

The 930T is nicely designed, with a sleek black finish and pocket-sized build. There are few controls on the exterior save for a power button, but the interface is so well designed that this isn't really a problem. On-screen buttons are large and easily accessible, and the massive range of features on offer has been effectively condensed into an intuitive menu structure.

Tapping the map view opens the main menu, from which you can plan a route in a number of ways, pair a mobile phone via Bluetooth, manage favourites, itineraries and maps and access music and media. The ‘Help Me' feature offers guides, advice and instant directions and contact details for emergency services, and a range of preferences offers full control over customising the interface and information provided en-route.

The massive range of features, adaptability and usability of the 930T makes it the most desirable in-car GPS device on the market.
