In need of directions? Wired finds its way around the latest in-car electronic maps.
Using a car with inbuilt satellite navigation as one of the test subjects, wired mounted the other four along the dash for comparison. Driving from London to Cornwall, we considered routes, estimated time of arrival, live traffic updates and general ease of use along the way. Driving on minor roads and tracks in an attempt to get lost helped to determine the accuracy of each device and its ability to put us back on course.
By detecting signals from Global Positioning System (GPS) satellites these devices can plot your precise location and show it to you on a map database that includes points of interest and speed camera locations. These satnavs go a step further adding real-time traffic information via RDS or 3G signals.
Check out the gallery to see the satnavs and our verdict.
