Safety camera information is included, and warnings pop up in good time to ensure you are within the limit. The database includes regular fixed cameras, mobile cameras, average speed areas and cameras associated with traffic lights. You can configure how warnings appear for each of these types individually. However, as with all other sat-navs, the safety camera information comes as a 12-month trial, with a three-year subscription costing £72.78. An even better deal is the 24-month Total Refresh Pack which provides the latest maps and safety camera locations as a bundle.
The main menu also features a Traffic icon, but this is only activated when the optional RDS-TMC receiver is attached. Mio hasn't published specific prices for the M400 yet, but the price of this accessory for similar devices tends to be £63.75.
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.
