At least HD Traffic and other options work properly now thanks to the built-in modem - we found that previous models struggled to maintain Bluetooth connections to some mobile phones, rendering Live services almost useless. The TomTom GO 940 Live is a big step up in this regard.

One thing TomTom still hasn't cracked though is on getting the automatic day / night modes right. Even in the dark we still had to delve into the TomTom GO 940 Live's menus to get it to switch. Voice quality from the rear-mounted speaker is also poor, with noticeable distortion at even reasonable volume levels.

So should you buy one?

If your heart rules your head then yes of course. It terms of usability, features and finish, it's easily the most accomplished TomTom GO yet, but you really have to weigh up how many features you'll think you'll need on a day-to-day basis in order to justify that enormous price tag.

At £449.99 then the TomTom GO 940 Live is probably better suited to motorway-munching road warriors than families heading out for an away day.
