If you're looking for a simple navigation device but can live without unnecessary bells and whistles, Mio's Digiwalker C250 is a decent bet. A quick tap on the Mio maps icon, followed by the address icon, then 'other city' and you're ready to specify your destination. Aside from turning it on and off, everything is done via the touchscreen on the 3.5in display.
Most of the icons are big enough to ensure even those with larger fingers are unlikely to have trouble negotiating menus. The onscreen qwerty keyboard, with its slightly smaller buttons, makes a good effort at picking up your attempts to type in addresses and postcodes.
The Digiwalker is very responsive and won't keep you waiting unless you've asked it to calculate an extremely complicated, cross-border route. It worked out a sensible route for a journey from central London to Aberdeen in 15 seconds.
The cockpit interface is uncluttered, roads are clearly marked and you can switch to a high-contrast mode when driving at night.
We were reasonably impressed with the accuracy of the maps – except when the Mio encouraged us to make an illegal u-turn at a set of traffic lights. Other than that, the instructions were clear and gave us plenty of warning before a manoeuvre was needed. If anything, the Mio was a little bit too eager to repeat an instruction, but those with a short attention span will appreciate the effort.
