Mio Digiwalker C520t

Flashnav!

Mio's last satnav, the H610, had many virtues, including a handy bra-size converter, but was let down a little by its puny screen. That's a criticism that can't be levelled at the C520t, whose lissome front is dominated by a 4.3-inch touchscreen. Once you get past packaging that would stump Handy Dave, the UK's current Mr Dextrous, you're greeted by a user-friendly interface.

Satellite lock-on is zippy, and route recalculation the quickest we've experienced, taking about a second - we know this very precisely, because we hadn't quite finished saying "one elephant" and it had re-routed.

The Mio's clear Western Europe maps can be viewed full-sized or with an info bar overlaid. Voice directions are impeccably pronounced - no riff-raffish estuary English here.

Text-to-speech is not included, but we can forgive that as you get free traffic alerts and speed camera updates (the latter for a year), Bluetooth for handsfree calling, an MP3 player, picture viewer, thousands of POIs and an SD/MMC card slot for memory expansion. But that bra-size converter? It's gone. Darn.
