With tiny dimensions and the smallest windscreen mount we've seen, the Tom Tom is perfect for modest navigators' pockets. However, its very dinkiness causes complications; the absence of buttons and a stylus is noticeable when contending with a 3.5in touchscreen. Still, as long as you're not a total klutz, the screen should be sensitive enough. The Tom Tom's interface is intuitive, stemming options from one menu. This system proves far more effective than those satnavs that involve exiting navigation before accessing the settings.
Maps follow a similarly simple ethos. A bundle of useful info is immediately obvious. Signpost information is displayed where available, while postcode navigation, compass directions and left-handed operation are all nice inclusions. Several voices are included and, although they aren't free, further alternatives can be downloaded.
In use the Tom Tom One is competent and accurate, but we found its route recalculation a little over eager. The Tom Tom often became confused if we didn't immediately follow its instructions, trying to recalculate our route unnecessarily. The screen clarity is good and the choice of car, pedestrian and bicycle routes useful. Traffic support, available on subscription via your mobile's Bluetooth connection, is another neat addition.
