1. What mapping choose?
You can choose between a France that mapping core team all systems (CD-ROM for the fixed positions, embedded memory for mobile). If you do not travel outside the borders, no need to invest in a more expensive camera will offer Europe on DVD or on a hard drive larger capacity. Two providers TeleAtlas and Navteq mapping, spurred by Viamichelin in France, share the market. There is little difference between the three.
2. And if I travel in Europe?
If the answer is “often”, then choose a system whose mapping is integrated Europe. If the answer is “occasionally” choose a system that offers to download the maps via the Internet or via memory card.
3. Button, remote control, stylus or touch?
Ergonomics is one of the main qualities of a good GPS system. The choice is yours depending on your usage. The touch screen is still preferred.
4. How to read a data sheet?
- The processor speed is specified in MHz. The higher the number the higher the speed of calculation is faster and therefore more quickly you will be on track if you deviate from the route.
- The flash memory is the memory size (in MB), like a digital camera or phone. Then it is important, the mapping will be more extensive.
- See also the associated connector (USB, memory card), important for connecting other devices like cameras or MP3 player.
5. The sound quality is important?
It is essential. Do not judge a GPS quality graphics but with that voice. Indications sound you avoid leaving the eyes of the road to watch a screen size is not always compatible with driving. Some nomads, most expensive, can plug into the speakers of the car.
6. Should we choose a compact system?
It depends on usage. For frequent use, prefer fixed navigation systems, more expensive, but more responsive and better quality for guidance. For occasional use or if you change your car often, nomads are perfect. As for PDAs and other SmartphonesFew ergonomic use of the waterway must be punctual.
7. Should we choose a system scalable?
Sure. New maps, updated radar points or points of interest (POI), changing the GPS have a shelf life much longer.
8. GPS systems-they are all equipped with traffic information?
All GPS fixed offer traffic information. This is absolutely not the case for all nomads, let alone PDAs.
9. The price differences are justified?
Yes. The processor performance, storage capacity, the screen size, the number of connectors, the size of the mapping, all this is paid.
