The 7310 also includes Navigon's voice activation system. This is a little more limited than the implementations of some other manufacturers, but still effective. A button on the initial screen calls up the system, giving you the opportunity to enter an address verbally by city, street and number. Since the range of possibilities is limited to existing addresses, this is quite an effective process, picking up every address we tried accurately, even with background car engine noise. In fact, the process is a little quicker than using the alphanumeric keyboard, particularly as it isn't QWERTY. The only annoyance is that you have to wait for a beep after being verbally prompted for each stage of the address, which is counterintuitive.
The 7310 includes the latest Navigon features, which we first encountered in the 3310 max. Most significant amongst these is MyRoutes, which is similar to TomTom's IQ Routes. Instead of merely basing its navigation on road speed limits or distances, MyRoutes takes historic traffic information into account, as well as day of week and time of day. So routes will be different during weekday rush hour than on Sunday morning. Unlike TomTom's IQ Routes, however, you are given three choices of routing, allowing you to select the one which suits you best.
Another new Navigon innovation is Clever Parking. This is really just a development of parking Points of Interest, but nonetheless useful. As you approach your destination, a P sign appears onscreen. Clicking on this calls up a list of nearby car parks, so you can quickly find somewhere to leave your car at your destination. Similar is POI Click, which allows you to touch the points of interest you see onscreen to reveal more details about them. When POIs are tightly packed, clicking on one calls up a list of all nearby POIs, so you can choose the one you were actually interested in.
The final new addition is MyReport, which again apes a feature TomTom introduced a couple of years ago (Map Share). Instead of having to grin and bear it when the roads don't match your map, you can use MyReport to make a note of the differences on the sat-nav itself. You can add map or safety camera changes. The map options cover new house numbers, streets, and roundabouts, plus changes in driving direction, speed limit and street name. The safety camera option actually includes changes in speed limits (again) and control direction as well as just adding or removing safety cameras. Your changes are uploaded to Navteq when you sync the device with a desktop computer.
