The Mio Navman M400 is no feature-rich powerhouse. In fact, apart from the free search facilities for addresses and POIs, it's actually a bit behind some of its competitors in this respect. But then there's the price. We were particularly impressed by Navigon's 1210 for providing adequate features alongside full Western European maps for under £100. But the M400 offers the latter with a better interface and a 4.3in widescreen for similar money. So if you're after a functional budget sat-nav for European travel, or even just everyday use, the M400 is a bargain.
