TomTom One

The basics

The Tom Tom One 4th edition is TomTom's entry-level automotive navigating system. It provides the driver with information about the closest and most efficient routes and boasts one of the simplest user interfaces around. It also includes pre-installed safety camera locations, a 3.5-inch touchscreen, measures 92x78x25mm and weighs 148g.

The good

Navigating with TomTom is like having a secret Government permit that opens up roads just for you – maps are cartoony but clear, voice directions calm but accurate and the routing rarely stumbles. The comprehensive database of safety camera locations must be costing local councils millions every year, and the unit is small enough to slip into a pocket when you park somewhere dodgy. If you’re not part of the AA, check out the Regional Assist versions. It costs about £15 more, but they include a year of breakdown assistance. A real bonus for owners of old bangers

The bad

TomTom is pretty ruthless about its pricepoints, so this budget model skips an SD card slot for map upgrades and lumbers you instead with a small 3.5-inch screen and meagre battery life (under two hours) that’s barely enough to pop to the shops without plugging in. There’s no Bluetooth, either.

The bottom line

This is the satnav to buy for your mum or techno-phobe mate. For just over a ton you get an excellent navigation tool, with none of those confusing (but sexy) techy extras.
