Slimmer and smaller than previous TomTom devices, the One Europe’s 3.5in screen reaches almost to the edge of the unit.

TomTom’s own software is intuitive, with logical touch-screen navigation and clear, easy-to-understand spoken directions. Should you miss a turn, the system usually re-routes to compensate, rather than just telling you to turn around.

The TomTom One Europe package represents good value for money, with maps for 21 countries included on SD Card and features such as Bluetooth.

One criticism of the TomTom One is its reliance on additional pay-for services. While some manufacturers are beginning to include free traffic alerts as standard, for example, TomTom only allows you to enjoy a month’s worth of its traffic service before you have to start coughing up.

The TomTom PLUS service offers lots of extras but, again, you need to pay for these separately.
