 MapSonic Onboard navigation: have you heard about the PDA solution using MapSonic navigation software? | New technology and mobility Your in-car navigation system: Remember to update your navigation CD-ROM! If your car has an in-car navigation system, then you know it works by using GPS technology. But did you realise that all the digital mapping and practical information is actually contained on a CD-ROM (or a DVD-ROM) which you should update regularly? GPS is an acronym for Global Positioning System, based on a network of satellites transmitting information received by the GPS antenna (the receiver) in your car. As long as the GPS antenna receives the signals transmitted by satellites (at least 4 are needed to register your position), your location is pinpointed and continually updated.
Take advantage of updated and ever more detailed mapping... Yet this marvellous technology would be nothing without the mapping and navigation CD-ROM. It is the CD-ROM which contains the map database and essential information such as hotel and restaurant descriptions and addresses from The MICHELIN® Guide as well as a wide choice of tourist and practical information. The precision of your GPS driving directions and guidance is based on the reliability of your mapping data. However, reliable data implies updated data. Did you realise, for instance, that a street name or one-way street can be changed by a mere municipal order; that, from one year to the next, whole streets can be turned into pedestrian zones and others might be reserved for solely buses and taxis - such as Trafalgar Square in London? ViaMichelin estimates that approximately 20% of mapping information is updated each year. That's why it is essential to stay updated with most recent versions of digital maps. Comparative tests have even shown that a driver can gain up to 15 minutes on a drive made with an updated version of a CD-ROM. Each year, impressive efforts are made to update and list new or revised roads, streets and locations. Geographers drive millions of miles annually in specially equipped vehicles inputting data in real-time. In addition, map coverage is also continuously expanding. From 2001 to 2004, map databases on Germany alone increased by 59,000 miles of roads in a country already considered to be 100% mapped. Map coverage for countries such as France and Italy is constantly increasing, so getting the latest CD-ROM version is a sound investment.
 ...and the added bonus of new tourist information With your in-car navigation CD-ROM, not only does it contain a mapping database but also all the MICHELIN® Guide addresses and descriptions. These are updated by Michelin inspectors every year, and the rate at which new addresses appear and others disappear can be an impressive 15%. As with mapping, reliable and updated tourist data is vital, allowing you, for example, to phone a hotel with the right phone number or go to a museum, knowing the correct opening hours. ...while benefiting from technical improvements In-car navigation is developing fast with many technological innovations. When you buy a navigation CD-ROM these days, you also gain from more user-friendly interfaces and more information saved in a compact format. This also enables you to discover further possibilities and features in your navigation system!
